The outcome of this systematic review work is explained in the following forms:
Design an optimization-based data cleaning model for dirty data detection and removal: The data cleaning model will detect and remove it from the system. This review paper identifies data cleaning as one of the major challenges in large application systems through studies based on [7, 19, 23, 27, 31,32,33,34,35]. Dirty data detection and removal can be performed through the optimization concept or nature-inspired algorithm (NIA). The detecting and corr Detecting and correcting include applications’ inaccurate, corrupt, and irrelevant ratification and removal: The second most promising challenge found in terms of identifying missing value from work based on [7, 24, 27, 36, 37]. Data analysis encompasses preprocessing of data, feature extraction, reduction of features, clustering, filtering, and classifications.
Design an outlier removal model: outliers differ from the existing standard data, deviating from the available dataset. However, several definitions of outliers exist, but no adequate explanation for removing the outliers in an extensive database system through clustering (An unsupervised model) could be the best outcome of this review. Outliers are an observation that appears different from a cluster’s standard data. It affects the results and calculations.
Big data: preliminary
Big data is a collection and combination of very large data in different formats that are difficult to store, understand, and process for an application. Big data falls under the categories of data analysis and streaming. Big data defines with the help of V’s, such as volume, variety, velocity, variety, veracity, vagueness, vocabulary, variability, venue, value, etc.
Big data generated through various sources, including healthcare, transportation, power grid, intelligent education energy, etc., must be classified as structured, semi-structured, and unstructured . It represents the scale of data that originated from various sources. The data’s size, amount, and volume are heterogeneous, and data volume is increasing exponentially. There is a 40% growth in total data generated every year versus a 5% only growth in IT expenditure. Around 90% of the world’s digitized data was captured in the last few years, and it keeps going on . Some challenges include the curse of modularity and dimensionality with a large volume of data in industrial applications where machine learning (ML) techniques are used to optimize and predict the outcome . Healthcare data increase dramatically as per . Machine learning is used to evaluate data modeling for large-scale data generation access points of an application to minimize computational cost and less memory and make a valuable model for predicting accuracy . The authors have explained big data for healthcare in parallel computing for volume, learning incrementally for velocity, and information fusion for a variety . Its emphasizes various applications’ input, analysis, and output .
It represents the different data types generated from various sources such as relational database systems, web text data, structured and semi-structured data, unstructured data, online data, social media data, healthcare sectors, etc. Processing and filtering data when required during processing in any application is complex. Data features, such as completeness and timeliness, are essential during accessibility in any system or application. For instance, knowing the weather condition of a particular city, the complete data set required, and timeliness reflects data availability for a specific duration. Variety is an attribute of big data associated with some challenges for industrial applications. Industrial applications are enabled with machine learning (ML) as a tool enclosed with some challenges: data locality, data heterogeneity (statistical, syntactic, or semantic), and dirty and noisy data. These data include different errors, different outliers, and missing values as well. However, data cleaning and outliers removal are critical challenges under big data analysis . Various data also includes textual, images, audio, video, XML, JSON, and sensors data.
It represents the speed at which data is generated, processed, analyzed, and stored at a distinct location in a big data system. Data are generated fast and need to be processed quickly as well. In an e-commerce business, promotions should be offered immediately to attract customers based on users’ transaction details. Velocity also represents the rate at which it is generated and analyzed. Some essential factors affect industrial processing tasks through machine learning, including data availability, real-time processing or streaming, and random variable generation . It is also defined as an “increasing data rate” within an organization. The velocity of data is essential for batch processing within industrial processing and other applications. Data streaming helps in machine learning-based processing in telecommunications and information technology-based industries. Many industrial applications require real-time data and processing task/unit update machine learning-based software that receives data stream as in moreover, many V’s, such as visualization, veracity, value, virality, viscosity, and so on, concern thconcernsvalues contribution to big data analytics being changed from descriptive analysis to predictive analysis. Various data analytics categories define through text, visual, voice, network, and geospatial . Textual case studies include social media, academic papers, website reviews, company documents, etc., whereas visual analytics includes surveillance systems, CCTV, drone trajectory heterogeneous cameras, etc. . Big data provides designing analysis and execution management, one of the services under SaaS on the cloud . The importance of many v’s can be understood as:
Table 1 gives an approach of different V’s and its existing format. Value is the essential characteristic of big data, which provides meaningful and heterogeneous advantages to industries. Any amount is highly dependent on the execution of processes and data access. For example, a weather forecast requires any random data that would be enough to predict a forecast for a particular region. In contrast, continuous data is required for disease treatment, such as temperature measurement, etc. Similarly, customers’ data are essential in banking services before proceeding with a loan . Veracity refers to the quality of data used in the applications and systems. Since data used under any applications and system must be checked and analyzed. Veracity in big data (context, cross-validations) discussed in . The authors stated data science and big data are equally important for healthcare . Veracity tends to data processing strategies. Veracity reflects the trustworthiness of data, estimated in terms of accuracy.
Since noise is considered data, but no information can be extracted from it. Viscosity is another V that measures resistance to the volume of data; it improves the data streaming. Similarly, variability is defined as data differentiation in nature where different data sources exist, differentiated between important and noisy and faulty data. Visualization is an approach by which data relationships are shown in some form. Data visualization is a mechanism that suits presenting a few data sets (in the form of tabular, graphical, and circular) to deliver required and meaningful results with the support of tools and techniques.
Visualization supports through different stages (data identifications, acquisition, analysis, validation, and visualization). Data acquisition sources take place from multiple sensors . Data visualization can be more effective in different ways. For instance, data is compelling and more credible, correct information is not overcomplicated, has graphical representations and style, is colorable e, has a visual hierarchy, and focuses on the point during presentations. Data visualization makes data more valuable. Virality defines the speed which iinteractionactionss among the network. It amounts to the dataset’s many availabilities for data processing before its implementation in the applications. It also defines applying data sources from among different applications. The authors describe the importance and significance of data generations and utilizations of data in other dimensions, including service sectors, as mentioned in . It also reflects how big data is suitable for the applications like banking and securities, communications, media and services, education, government, healthcare providers, insurance, manufacturing, natural resources, retail, transpordutiesn, ties wholesale trades, etc. . Besides definitions of big data, many technologies, like machine learning algorithms, are useful for data analysis. It can be used to find a feasible solution for optimized and complex problems where data analysis problems can also be converted into optimization solutions . From the data mining perspective, noisy, outliers, and incomplete datasets are essential in big data analytics in an application. In diabetes, the machine learning algorithm (MLA) is used along with data mining technologies . However, in section IV, various applications of big data are described.
Few sectors, such as Banking (25%), Services (15%), and Manufacturing (15%,) are the three most active industries in making inquiries about big data to Gartner over the last twelve months. The adoption of big data in different sectors reached up to 53% . IoT and big data projects have increased as industries focus on data for decision-making systems for positive impact and business improvements . Crop yield improvement is another big data application area where production prediction enhances the agricultural field . Big data applications, features, and challenges of different industries are mentioned in . Big data is used effectively to improve smart farming and reduce wastage . Big data analysis is also helpful in improving the food supply network within agricultural-based industries. Similarly, the authors mention the importance of data mining, data analytics, cloud computing, machine learning, etc., in the big data paper .
Systematic big data analysis review

What is the need and importance of big data applications?
How is big data analytics suitable for industrial processing and the healthcare sector?
The application domain’s data life cycle identifies a verified problem like data filtering, outlier removal, and missing value.
The big data applications have been explained in Sect. 4. A comprehensive literature review was performed, keeping these above points in mind. In 2010, Apache HADOOP defined big data as “datasets which could not be captured, managed, and processed by general computers within an acceptable scope.” Based on this, in May 2011, McKinsey & Company announced big data as the next frontier for innovation and productivity . Big data is suitable for designing models, tools, and methods for different functions, including operational and clinical activities for the healthcare sector . This big data analysis review comprises other research papers, including business processing and health. The territory of big data is a vast and diverse one. Since big data has high scope in different sectors, big data analysis and technology reviews concerning a particular domain become important. It has been observed that automation generates data duplication and data entry errors in the system. There is a need to identify common challenges among sectors or applications that can be further researched and improve accessibility in different applications. Moreover, it is essential to know how big data support various sectors in today’s scenario, irrespective of challenges and issues in the usability of tools and techniques.
Since industrial processing task (including the manufacturing sector) encompasses through massive data set for quality evaluation of product and also used for future prediction of outcome for identifying the nature of the customer, prediction of selling product to end-user, price of the product, the end-user habit of purchase, etc. Since data sizes are growing fast; thus, the manufacturing process becomes complicated and complex to execute practically . Big data is suitable for process optimization and helps empower the decision process. Before giving the importance of any mechanism, we need to review the work done in this area with methodologies, features, and challenges. The research methodologies of selected research papers are based on the search mechanism “Big Data,” Big Data in Healthcare,” “Big Data in Industries,” and so on. Thus, Table 2 shows the details of the work done by the various authors.
So, the above articles show various methodologies and features used in different domains and applications. From the above research papers [7, 19, 23, 27, 31,32,33,34,35], the challenges found in different terms. It includes data cleaning, missing value, and outlier detection under various applications. It affects in the following ways: interaction among users, sharing of data through a common platform, high accessibility among users, social support, health-related clinical information, and health policy. Big data research projects need a search engine for healthcare, financial transactions, weather data., index structure, and search mechanism . In , the authors expressed data staging errors generated during integration, transformation, and migration. Since data generated for analytics must go through the data cleaning process, several errors such as whitespace removal and no. of zero’s for identified numbers are addressed.
Different simulations environment were used, including parallel computing, modeling, metaheuristic approaches, artificial intelligence environment, knowledge handling, data analysis, reporting, machine learning, deep learning, principle component analysis, outlier removal, cleaning model, and random forest machine learning algorithm, etc. in the articles mentioned above. Data cleaning models and outlier analysis are the most important simulation methods of various applications. Different experimental parameter used such as accuracy, sensitivity, specificity, FPR, FNR, negative NPV, and FDR were used to compare with the existing models [7, 19, 23, 27, 31,32,33,34,35].
More in-depth machine learning-based experimental analysis was executed to resolve processing performance, where dependency reduces. Deep learning improves classification performance, design pattern formulation, and evaluation models . It includes several steps, including preprocessing, feature selection, and text classification, and is evaluated and compared with global feature selection methods . Data analytics simulation is used for healthcare data. Automation is required for data storage, processing, and handling . Data analysis of manufacturing sector-based applications such as agricultural harvest and sorting plants have been discussed through data acquisition, distance-based, and regression-based approaches . Data acquisition tools are used for experimental analysis for different sectors. Data preprocessing is essential to execute data mining tasks to provide meaningful information. Data preprocessing tasks include cleaning, normalization, transformation, missing value imputation, data integration, noise identification, etc. . Because of the large volume of data and different data aggregators, it becomes difficult to maintain the data stream. Therefore, big data reduction methods are explained through network theory, compression, redundancy elimination, data preprocessing, dimension reduction, data mining, and machine learning as experimental approaches and methodologies to reduce and filter use valid . While dealing with large and voluminous data, data quality is enhanced by removing and identifying missing values, duplicate values, data heterogeneity, and data integration.
These are essential for big data and machine learning technologies . Similarly, when dealing with data quality and cleaning, outlier removal becomes important in sensor-based data. For outlier detection, support high-order tensor data description proposed in highly dimension sensor data . Since machine learning experimental analysis is imporessentialarious application incl, including healthcare, it is being applied to different test cases such as diabetics, heart diseases, and breast cancer. The experimental result compared with K-NN, support vector machine, decision tree, etc. . So, the data cleaning and outlier removal concept from big data was identified as the baseline for the subjective technological comparison mentioned above 2. In , the authors designed a deep learning framework structure, discussed the importance of IoT big data, and found that IoT generates a different type of massive data.

It shows how big data relates to different areas of knowledge. Hence, the authors believe in providing high-quality and complete solutions to such issues. Experts from other regions of multidisciplinary teams will also be necessary to identify data learning as important for evaluating high quality.
Big data infrastructure supports data collection, data storage and transfer, and computational technologies (Parallel computing, Hadoop distributed file system (HDFS), MapReduce, etc.) . The Hadoop tools are also required as a primary platform for cycle time forecasting under production planning and data preprocessing. So cycle time forecasting goes through essential platform establishment (HADOOP) and data processing (including data extracting, formatting, and data cleaning) . It is compared with the traditional database system under the enormous and increasing size of big data. According to Gartner’s report (October 2012), total IT spending is driven by big data given below.

Big data are valuable and helpful for various schemes. It helps the government understand the clusters of objects that provide end-users facilities. Collecting data sets helps the government identify areas and methods to profit the nation’s citizens. It includes data received from every transaction and other access to IT resources such as e-Mitra. Big data provides a platform for government officials to share and exchange information about the public’s direct beneficiaries of schemes. However, there are still challenges in filtering and accessing the correct data and information, a massive problem in a survey of below poverty line (BPL) and other schemes. The primary beneficiaries are still away from getting benefits from the government. So, the big data cleaning and clustering approach to data filtration help citizens access government resources on time. Data cleaning is also applicable in crop selection analysis in agricultural applications, where big data is used effectively .
Smart cities are the recent concern of big data applications where intelligent cities such as “smart health, smart logistics, smart education, smart transport, smart energy, etc.“ exist.

Challenges and opportunities in big data
Although many authors give various challenges, few are important such as big data imbalance, big data management, big data cleaning, big data analytics, big data aggregation, big data accessibility, and so on . These challenges are also described in big data management, imbalanced big data and system capacities, big data machine learning, and so on . There is a dissimilar hindrance to industrial big data analysis where innovative manufacturing-based systems must be implemented. It consists of long-term investment in IT infrastructure, and it’s difficult to move on automation for industries, industries regulations and constraints, protocol systems, low vision and commitment, risk association with the new technologies, etc. . Diversified challenges are found in the forms of a futuristic healthcare system that includes data format standardization, unified data schema, data quality parameter, aggregation scale, analytics tool, etc. , There are various other challenges such as data representation, data compression, redundancy reduction, data life cycle management, data confidentiality, data analytical mechanism, scalability and expendability, cooperation in case of interdisciplinary, and so on . Big data challenges also exist in data complexity, computational complexity, system complexity, and so on . However, there are several challenges in finding meaningful data, and big data is data mining, data storing, data sharing, data privacy, data technologies, and talent. Data sharing supports limited data standardization, information barriers, and insufficient data integrations in big data applications . In , the authors described a few challenges for big data as a compounding factor: dealing with missing data, duplicate data, data heterogeneity, semantic data generations, etc.
Some important and common challenges are available with big data in industrial processing and healthcare, including data storage, data quality, security and privacy, reliability and availability, big data filtering, big data processing tool, and big data analytics. Big data analytics and processing are challenging due to storage, networking, and limited computational access . In addition, more challenges with big data create hurdles for industries such as scalability, lack of professionals (data scientists), lack of appropriate data source with business objectives, security, and big data project cost evaluation and management. Various other challenges are also found in terms of data aggregation, data maintenance, data integration and interoperability, data analysis, and so on . Some implementation level challenges in the healthcare sector are data management (20%) and technological issues (10.2%). Here, lack of technologies would not be in a position to produce effective results, evaluation process(7.1%), financial issue (3.1%), regulation(5-0.6%), awareness(0.5%) and support, political issue (0.4%), etc. . So, the challenges and techniques through various research articles/papers/works in a consolidated form are mentioned below in Table 5. It represents the result analysis report of different healthcare and industrial processing works, including methodologies, features, and challenges mentioned in Table 2. This result analysis people 4) shows that data cleaning and outliers are important and have more weightage than other challenges.
From the literature review, the techniques below apply to the mostly application-based project, which is commercialized. In various literature review articles, it was found the performance measure in terms of accuracy, sensitivity, and precision [34, 125, 147,148,149]. Most of the article has worked with healthcare and industrial data taken from various SCI, SCIE, SSCI, ESCI, Web of Science, Scopus, etc., from 96 different journals and industrial processing-related articles, including 24 other journals. These technologies (as mentioned in Table 5), can also work together to improve the result for accuracy, sensitivity, precision, and specificity.
The proposed method for the data cleaning model and outlier removal has been given in subsections 6.2 and 6.3. Metaheuristics approaches have been preferred with machine learning to provide better healthcare and industrial data results. It has been observed; that metaheuristics are suitably applied in classification, clustering, feature selection, and association rules during experimental analysis. Table 5, shows that enhanced data cleaning and outlier detection models are required to meet noise/dirty free data for the growth of industrial performance analysis. Noisy and insufficient data will not be sufficient to conclude any applications.
Big data filtering
Data filtering encompasses several steps in many applications and provides better results, leading to the success of the application system in industries . Big data is a critical approach for the industrial database system . Since many sectors, such as telecom, e-commerce, banking, insurance, health, etc., rely on data generated by other authentic se such as banks, data filtration becomes essential in all respect . It helps to ctorremove noise, incorrect, inappropriate, incomplete, and duplicated . Data quality is affected by many factors, such as accessibility, completeness, accuracy, ease of understanding, value-added, etc. . So these factors affect data quality in diverse ways .
However, the system’s dissimilar error must be resolved before processing and analytical applicability evaluation in any system . Data filtering includes measurement of error, inconsistent data(e.g., duplicate data, values out of band, error code, contradictive error, etc.), outlier, missing data, etc. .The challenge is how to perform and provide the complexity of big data nature (volume, variety, velocity) in a better way. It leads to an evaluation of the reliability analysis approach, which identifies the relationship and complexity of the nature of big data . At the same time, it is also essential to manage data collection, integration, and storage with few hardware support and software requirements .
Proposed data cleaning algorithm
From the literature review [60, 62, 63, 68, 75, 84], it was identified the problem of data cleaning in the form of text classification, sentiment analysis, text clustering, etc., along with cleaning behavior and algorithm usability. Moreover, the Kalman filter mechanism fails to support extensive sensor data, which is a part of data generation sources in industries and the healthcare sector. The recent research of the year 2018 also identified the big data processing problem and data cleaning problem in big data processing. So far, different conventional data cleaning processes and methodologies exist suc,h as interest constant conditional functional dependency (ICCFD)_miner techniques, systematic sampling method, wavelet-based multiresolution analysis technique (WMAT), algebraic method, fuzzy Kohonen clustering network (FKCN) algorithm, Rete algorithm, distributed principal component pursuit (D-PCP), stacked denoising autoencoder (SDAE), etc. These methods include several challenges: data repairing, high processing time, cleaning integration, high computational cost, distributed real-time cleansing, etc.
So, to solve the data cleaning problem, a new and novel mechanism is proposed to identify and detect abnormal data. This data cleaning approach would be in two phases: dirty data detection (DDD) and dirty data cleaning (DDC). Dirty data detection goes through data normalization, hashing, clustering, and finding the inappropriate data, and the messy data cleaning phase passes through leveling, Huffman coding, and removal of erroneous data. However, centroid selection is an issue in the clustering process and the removal of suspected data. So, these two issues can be solved through the optimization concept. In this case, a metaheuristics algorithm would be beneficial. For finding the suspected data under dirty data cleaning (DDC), a combined approach of rider optimization algorithm (ROA) and firefly algorithm (FF) can be considered. The performance of the proposed mechanism will be compared with the grey wolf optimization (GWO) and particle swarm optimization (PSO) on certainspecificters comprising false-positive rate (FPR), false-negative rate (FNR), precision, accuracy, sensitivity, specificity, etc. The healthcare dataset such as diabetics, heart, and breast cancer is required from UCI Machine Learning Repository .
Proposed outlier removal mechanism
From the review [7, 19, 23, 27, 31,32,33,34,35], it’s stated that outliers removal should be one of the critical challenges and opportunities in big data-based applications. Outlier removal is next under the data cleaning process. Outlier detections are parametric and non-parametric. Statistical methods fall under parametric, whereas non-parametric consist of density-based, clustering-based, and distance-based. The k-means clustering approach can be considered out of several outlier removal techniques because it does not require preliminary data information or knowledge. So far, different methods exist like k nearest neighbor (kNN), k-means with outlier removal (KMOR), generalized linear model (GLM), maximum correntropy estimator (MCE), maximum likelihood estimation (MLE), two-stages, and standard operating procedure (SOP). All outliers will be placed into a single cluster in the proposed outlier detection model so that it would be based on a k-means clustering process called enhanced k means outlier detection model (E-KMOR). However, k-means with optimal centroid would be an approach where centroid selection is carried out through an optimization mechanism.
So, to solve the optimization problem, a coma hybridoach of lion algorithm (LO) and particle swarm optimization (PSO) was proposed. The proposed enhanced k means outlier detection model (E-KMOR) would be compared with the existing generalized linear model (GLM) and K-means outlier removal model (KMOR) based on parameters such as accuracy, sensitivity, specificity, and so on. The weakness of this outlier detection model may fall under data volume. It needs large dataset values of any application. The proposed E-KMOR is an extension of the K-mean algorithm and does not apply to data compressing. The future work may be towards implementations of EKMOR towards data sampling.
The big data processing tool
Many tools support big data compatible with cost efficiency, timing, accuracy, etc., to perform data analysis tasks under massive datasets . Developing large-scale, accurate, adaptive, error-free, and fault-tolerant systems is complex . Some essential big data processing tools are HADOOP, MapReduce, HPCC, Storm, Qubole, Cassandra, Statwing, CouchDB, Pentaho, Flink, Cloudera, etc. An experimental big data framework for machine learning and graph processing is mentioned in .

HADOOP can execute voluminous data in a few seconds with the support of parallel clusters and distributed file systems . It has been designed to reduce timing complexity and space as well. It performs fast because of the Hadoop distributed file system (HDFS) and MapReduce. HDFS can store different types of data formats of large volumes.
The beauty of HDFS exists in heterogeneous hardware and software platform-independent . MapReduce is used for data processing through job scheduling and resource management. One of the programming models under HADOP effectively reduces massive data processing complexity . MapReduce performs execution in four stages: map function, key-value pair with the mapper, reduce function, and store key-value pair in the output file . These tools help in multiple ways: framework design, a data computation system, a data management platform, an architectural structure for data processing, and statistical tests automatically for the massive volume of data . Big data tools are used to develop and design healthcare frameworks through data integration tools, scalable searching, processing tool, machine learning tools, real-time and data stream processing tools, visual data analysis tools, etc. ,
Big data analytics
For various application areas, big data execute transformative potential to harness such vast volumes of data. Advanced data analysis tools are required to measure the relationship among features and explore data at a lower level of access . Big data applications need real-time analysis for practical evaluation through data processing models such as predictive analysis, NoSQL database, Search & knowledge discovery, stream analytics, distributed file sore, data virtualization, data integration, etc. Data analytic tools such as (Tableau public, OpenRefine, KNIME, RapidMiner, Google Fusion Table, NodeXL, Wolfram Alpha, etc.)are used under big data to meet the required services of industries . Big data analytics enhances operational efficiency, decision- making, market demand prediction, etc.
Healthcare-based industries use artificial intelligence mechanisms such as machine learning (ML), agent-based (AB), heuristic-based (HB), cloud-based (CB), and hybrid-based (HB). These techniques are implemented through big data on various factors to enhance reliability, efficiency, accuracy, performance, availability, QoS, etc. . The parameters (accuracy, sensitivity, specificity, FPR, FNR, NPV, etc.) would be used in the proposed work to compare the existing algorithm such as PSO, FF, GWO, etc. These parameters are used in test cases of experimental work. Since various iterations are performed, so it becomes essential to use. The advantages and disadvantages of machine learning are given in .
Future research outline
Various challenges exist in big data that need to address. However, challenges may include new technologies, scaling data processing techniques in big data, big data learning paradigms, data sources, attributes, smart cities, etc.
It is clear from Sect. 6.4) that big data processing tools offer various services that need to be verified effectively for any system before using it. In the case of Spark, which performs better than HADOOP in processing . Spark is the latest technology, and it will take time to develop concepts . Similarly, Flink is another emerging technology platform that reduces the gap between stream data processing and batch processing.
Flink’s core supports data allocation, message, and fault tolerance for dispersed computations over data streams. Whereas in the case of scaling data processing technology, the majority of tasks (such instance, reduction, missing values imputation, and noise treatment) need to resolve sincerely . Apart from these, the optimization of big data techniques is equally important . However, the big data learning paradigm includes unsupervised, semi-supervised, data stream, and non-standard, apart from classification and regression methodologies . Different analyzing tools can be considered in classification, clustering, regression analysis, and association rules applicable after generations of large and voluminous data in healthcare sectors . Different clustering techniques exist, such as hierarchical-based, partitioning-based, density-based, grid-based, and model-based. These clustering methods can also be used in healthcare and industries . Data sources and attributes are essential in the case of data sources and features, and their variants in different forms are also challenging to manage . Modern industries require a novel method and process improvement for big data analysis.
In industrial processing, cloud computing-based solutions are needed for ample data storage and analysis. For controlling and monitoring, generous data tools support must be focused on. Big data analysis is required for many industries’ multiple and customized ERP solutions.

These methods worked on healthcare, other applications, and industrial data, where results improved for better services. However, effects can be enhanced regarding existing and studied measured parameters, including accuracy, sensitivity, specificity, and precision. In the proposed work, a few other significant measurement parameters can be added, such as false-positive rate (FPR), false-negative rate (FNR), negative predictive value (NPV), and false discovery rate (FDR), and F1_Score, for higher and more effective results. These results would improve the timing complexity of the system to perform. Timing complexity improves once accuracy, sensitivity, and specificity enhance.
Big data analytics (BDA) in manufacturing identifies some crucial challenges which can be further taken up for improvement in terms of quality and process control system (QPCs), proactive diagnosis (PD), etc., before the implementation of BDA. Big data values such as performance improvement (PI), transparency, and decision support system (DSS) would be the objective for further improvement. Sustainable smart manufacturing, where data and services integrate to provide business outcomes, requires the effective integration of data sources. The significant outcome state requires a data cleaning model to detect and rectify anomalous data. Dirty data identification, removal, and outliers are essential issues in big data-based healthcare and industrial applications.
