Abstract
Extraction of valuable data from extensive datasets is a standout amongst the most vital exploration issues. Association rule mining is one of the highly used methods for this purpose. Finding possible associations between items in large transaction based datasets (finding frequent itemsets) is most crucial part of the association rule mining task. Many singlemachine based association rule mining algorithms exist but the massive amount of data available these days is above the capacity of a single machine based algorithm. Therefore, to meet the demands of this evergrowing enormous data, there is a need for distributed association rule mining algorithm which can run on multiple machines. For these types of parallel/distributed applications, MapReduce is one of the best faulttolerant frameworks. Hadoop is one of the most popular opensource software frameworks with MapReduce based approach for distributed storage and processing of large datasets using standalone clusters built from commodity hardware. But heavy disk I/O operation at each iteration of a highly iterative algorithm like Apriori makes Hadoop inefficient. A number of MapReduce based platforms are being developed for parallel computing in recent years. Among them, a platform, namely, Spark have attracted a lot of attention because of its inbuilt support to distributed computations. Therefore, we implemented a distributed association rule mining algorithm on Spark named as AdaptiveMiner which uses adaptive approach for finding frequent patterns with higher accuracy and efficiency. AdaptiveMiner uses an adaptive strategy based on the partial processing of datasets. AdaptiveMiner makes execution plans before every iteration and goes with the best suitable plan to minimize time and space complexity. AdpativeMiner is a dynamic association rule mining algorithm which change its approach based on the nature of dataset. Therefore, it is different and better than stateoftheart static association rule mining algorithms. We conduct indepth experiments to gain insight into the effectiveness, efficiency, and scalability of the AdaptiveMiner algorithm on Spark.

Introduction
Data mining techniques like classification, recommendation systems, clustering, and association rule mining are highly used to extract the useful or relevant information from large datasets. Association rule mining is one of the best techniques to mine relevant information from large datasets. It produces relevant or interesting relations between different variables in the dataset in the form of association rules. For example, an association rule bread \(=>\) butter (90%) states that nine out of ten customers that bought bread also bought butter. To generate such association rules, frequent patterns must be identified first. Therefore, frequent pattern mining forms the crux of any association rule mining process. To find frequent patterns, we need to get support for every itemset in the database. Itemsets with support more than minimum support are considered as frequent itemsets. In association rule example, 90% shows confidence or accuracy of the rule.
For example, I is a set of products (items). A set X = {\(i_1, i_2,....,i_k\)} \(\in\) I is called as kitemset. A transaction over I is a pair \(T= (tid, I)\) where tid is transaction ID and I is an itemset. A transaction database is a set of transactions having itemsets \(\subseteq\) I.

Crime prevention/detection Frequent pattern analysis of huge criminal databases that contain criminal events/activities can help to predict the most crimeprone areas in the city or predict the criminals/thieves that are most likely to be repeat offenders [1, 2].

Cyber security Frequent pattern analysis of large network log files can help identify different IP addresses and ports that are highly susceptible to attacks [3]. This information can be used to block requests from these vulnerable ports or addresses.

Crowd mining Extracting useful patterns from large databases of social sites allows a better comprehension of crowd (large group of people) behavior which in turn can improve possibilities of increasing sale and monetary gains [4, 5].

Bioinformatics Analyzing sequence alignment results to find interesting information related to the human genome and motif discovery [6].
The paper is organized as follows. After introducing the motivation in “Introduction” section, earlier work about frequent itemset mining, mainly MapReduce based Apriori algorithm is reported in “Related work” section. “AdaptiveMiner algorithm” section has detailed description of the AdaptiveMiner algorithm proposed in this paper. “Evaluation” section shows performance analysis of conventional Apriori, RApriori, and AdaptiveMiner on Spark. “Conclusion” section concludes the paper.
Mapreduce and Spark
With the availability of cloud computing technologies like Amazon EC2 cloud and Microsoft Azure, as evolutions to accommodate computing and storage service as a utility at very affordable prices, users can use these cloud services via internet from home or workplace by paying for resources consumed without worrying about availability, maintenance and flexibility issues. Cost is based on the type of service and time of service. Therefore, cloud computing has emerged as a very promising solution for demands of storage and computation in research eliminating the need for powerful and high computing capacity server. But to achieve efficiency, performance, and scalability for processing huge data, a highly parallel distributed computing model is required. Therefore, a parallel computing framework called MapReduce [21] was designed by Google which allows using thousands of commodity machines in parallel. MapReduce framework works on a basic idea of the flow of \(\langle key, value \rangle\) pairs through the map and reduce phases. Input is split into fixed size chunks and distributed over available mappers. Every mapper processes its chunk of data and generates \(\langle key, value \rangle\) pairs. These \(\langle key, value \rangle\) pairs are shuffled or sorted to group values based on keys to generate intermediate \(\langle key, value \rangle\) pairs where all values with the same key are grouped together. Reducers take the intermediate \(\langle key, value \rangle\) pairs and combine all values for a key to generate final results. MapReduce framework can handle huge datasets because all map and reduce operations are executed concurrently on many machines. All map tasks need to finish to start reduce tasks. Many MapReduce framework based tools like Hadoop, Spark, and Flink are available to analyze huge datasets with ease. Hadoop is widely used MapReduce based model in bioinformatics in recent few years. Sequence alignment tools like IMRApriori [22], MRApriori [16] and BigFIM [23] used Hadoop for heavy analysis. Though Hadoop provides a highly parallel computing environment but has a limitation of high I/O time during various iterations. Apache Spark [18] overcomes this limitation of Hadoop by using its inmemory computing technique with the help of RDD storage. I/O operations on Spark RDD [18] are very efficient and fast due to which sometimes it outperforms Hadoop by 100 times. These advantages of Apache Spark ignited an interest in us to use Apache Spark for our association rule mining algorithm AdaptiveMiner.
Related work
During last three decades, a lot of association rule mining algorithms are proposed by researchers. These algorithms were fast and efficient until the evolution of Big Data in last decade. In an era of Big Data, data is produced at such high speed that these algorithms are unable to keep track with that. Therefore, association rule mining algorithms based on parallel and distributed computing has evolved as a solution. Most of these algorithms were based on MapReduce paradigm. Apriori is one of the simplest and easily parallelizable algorithms. Therefore most researchers use Apriori approach for implementing MapReducebased association rule mining algorithms.
In 2008, Li [24] proposed an association rule mining algorithm called as PFP (Parallel Frequent Pattern). This algorithm is a parallel implementation of FPGrowth (Frequent PatternGrowth) algorithm based on MapReduce paradigm. It eliminates the requirements of data distribution and load balancing by using MapReduce paradigm. It was highly scalable and quite suitable for web data mining. PFP search for topk patterns instead of patterns fulfilling user specified minimum support criteria which make it effective for web data mining. Author apply it on query log for search recommendations. PFP load balancing technique was not so efficient, therefore Zhou [25] proposed a new algorithm called as BPFP (Balance Parallel FPGrowth). BPFP algorithm has better load balancing technique to make PFP faster and efficient.
In 2010, Yang [26] proposed a very simple MapReducebased association rule mining algorithm. This algorithm was the very straightforward implementation of Apriori algorithm on Hadoop. It uses a single map and reduce phases to get frequent patterns. In 2011, Li [27] proposed a new cloud computing based association rule mining algorithm which uses one phase MapReduce implementation of Apriori. They used better data distribution techniques to improve efficiency and speed. An entirely different approach is used by Yu [28] for mining association rules. They replaced the original transactional database with the boolean matrix. Now many AND operations along with other logical operators are used on matrix to find frequent patterns. It uses Hadoop for parallel computation of matrix by dividing it into parts. They claim for better space and time efficiency.
Some researchers focused on using cloud computing platforms like EC2 and S3 for fast and efficient association rule mining.
In 2012, Li [13] proposed a MapReducebased association rule mining algorithm and ran it on Amazon EC2 cluster. This algorithm uses basic apriori approach. It provides faster results due to high computation power available on EC2. It uses Amazon S3 for data storage. Later, lin [14] proposed three MapReducebased association rule mining algorithms called as SPC (Single Pass Counting), FPC (Fixed Passes Combinedcounting), and DPC (Dynamic Pass Counting). SPC algorithm is simple MapReduce implementation of Apriori. FPC algorithm works same as SPC for finding up to 2itemsets. It combines candidate sets for remaining passes to get results in a single phase. It was useful in some cases where the size of candidate set is small after two iterations and many machines in Hadoop cluster remain idle during afterward steps. By default, FPC combines candidate set of 3 iterations like candidate set of 3itemsets, 4itemset and 5itemset. FPC also has a drawback that it combines fix number of passes and have the possibility of crashing if candidate set for higher iterations is large. DPC algorithm resolve this issue quite efficiently by combining phases depending on candidate size and machines computation power. It provides better load balancing for increasing efficiency. In the same year, Li [15] and Yahya (MRApriori) [16] proposed another MapReduce paradigm based association rule mining algorithms which are a straightforward parallel implementation of Apriori algorithm.
Some researchers use random samples of the database to find approximate association rules. PARMA (Parallel Randomized Algorithm for Approximate association rule mining) [29] algorithm gives input of random samples of the database to various machines in the cluster. Every machine finds frequent patterns for its sample and reducer combines the results. This algorithm does not provide accurate results, but allow the user to define his choices for allowed error percentage. A random sample is fixed in size and depend on userdefined allowed error rate. It has a drawback of less accuracy as compared to existing MapReducebased algorithms. In 2013, Kovacs [30] used a different approach that they calculate singleton and pair frequent itemsets in the first iteration of MapReduce using triangular matrix. Candidate set is generated in reduce phase instead of map phase in all existing MapReducebased algorithms. Later, Oruganti [31] used parallel Apriori implementation using MapReduce paradigm to explore Hadoop capabilities. In the same year, Yong [32] proposed an association rule mining algorithm based on MapReduce paradigm which uses cloud computing to run parallel implementation of FPGrowth. It has two major benefits over conventional parallel FPGrowth algorithm. Firstly, it reduces database scans, and secondly, it reduces the cost of interprocessor communication in conventional parallel FPGrowth algorithm. Later, Moens [23] proposed two association rule mining algorithms called as DistEclat (DistributedEclat) and BigFIM. DistEclat works on the concept of Eclat algorithm. It is MapReduce paradigm based implementation of Eclat algorithm. It concentrated more on speed and suitable for faster results. BigFIM works on a hybrid approach. It uses both Apriori and Eclat algorithm mixed approach. It is more appropriate for handling large databases in an optimized way. In the same year, Farzanayar [22] came with IMRApriori (Improved MapReduce based Apriori) algorithm to analyze massive social network data.
In 2014, Lin [33] came with one more MapReduce paradigm based parallel implementation of Apriori. Lin uses most outdated cluster hardware (P4) for computations. Later, Barkhordari [34] proposed a MapReducebased association rule mining algorithm called as ScaDiBino (scalable and distributable binominal association rule mining algorithm) which converts every row of input transactions to a binomial format. Binomial data can be processed more efficiently on MapReduce. This algorithm directly generates association rule without finding frequent patterns. They used this algorithm for recommending value added services to customers by analyzing network traffic of a mobile operator.
Some researchers use various data structures to improve the efficiency of association rule mining algorithms. Singh [35] tries to use a hash table, hash trie and hash table trie for candidate storage in Apriori MapReducebased implementation. They find that hash table trie is most efficient than others in MapReduce context while it is not much efficient in a sequential approach.
On Hadoop platform, results are stored in HDFS (hadoop distributed file system) after every iteration, and these results are again sourced from HDFS as input for the next iteration, which decreases the performance due to the high I/O time. But Spark [18], a new inmemory, distributed dataflow platform, resolves this issue by using its RDD architecture. RDDs stores the results in main memory at the end of an iteration and make them available for the next iteration. Traditional Apriori implementation on Spark platform gives many times faster results on standard datasets which make Spark one of the best tool for implementation of Apriori. In 2014, Qiu [19] had reported speedups of more than 18 times on average for various benchmarks for YAFIM (yet another frequent itemset mining) algorithm based on Spark RDD framework. Their results on realworld medical data are observed to be many times faster than on the MapReduce framework. Later, Zhang [36] proposed an association rule mining algorithm called as DFIMA (Distributed Frequent Itemset Mining Algorithm) which is implemented on Spark. DFIMA algorithm uses matrixbased pruning technique to reduce candidate size. The author claims that it outperforms PFP algorithm when both are implemented on Spark. Recently, our new association rule mining algorithm called as RApriori [20] used a reduced approach for 2nd iteration to reduce computations. RApriori outperformed nearly all stateoftheart association rule mining algorithms for 2nd iteration in terms of accuracy and performance. These results motivated us to come with innovative approaches for distributed association rule mining algorithms.
AdaptiveMiner algorithm
AdaptiveMiner is a MapReduce based parallel algorithm implemented on Apache Spark. It has two phases.
Phase I In the first Phase, all frequent singletons are mined from the dataset. This phase uses a single iteration of Map and Reduce to discover all frequent singletons. All frequent singletons are stored in Bloom filter. Apriori uses Hash tree to store and search candidate itemsets which have the limitation of false negatives. Therefore, Hash tree is replaced with Bloom filter to improve accuracy for association rule mining.
Phase II In the second Phase, algorithm finds all frequent itemsets of length 2, 3, 4 and so on. This phase uses many iterations of Map and Reduce until there is no frequent itemset for an iteration or maximum iteration limit is reached. In phase II, it makes execution plans for every iteration, compute the cost of execution for every plan and then select the best plan for that iteration. This algorithm uses a dynamic approach which makes it faster and gives efficient results for every iteration. There is some overhead of calculating the cost for every execution plan, but this overhead is negligible when we are working on large datasets.
Phase I—frequent singletone generation
AdaptiveMiner finds all frequent singletons from large transactional datasets during the first phase. The transaction dataset from HDFS is loaded into Spark RDD to make good use of cluster memory and also provide resilience to failures in the cluster. The detailed process of generating a frequent singleton itemset from the dataset is outlined in Algorithm 1.
Example
Figure 2 shows an example of singleton frequent itemset generation step. A transactional database stored on HDFS is treated as the input. The mappers in the first round receive a set of transactions (e.g. mapper MAP1 receives transaction T1–T2) and they split each transaction into items and generate corresponding \(\langle key, value \rangle\) pairs. For example, transaction T1 (S, R, M) is mapped to \(\langle S, 1 \rangle\), \(\langle R, 1 \rangle\), and \(\langle M, 1 \rangle\). Subsequently, a reduce task combines all pairs according to the key (reduceByKey function) and filter out pairs having value less than minsupport. At last, results are stored in Bloom filter.
Phase II—frequent itemsets generation
AdaptiveMiner uses an adaptive approach and select conventional or reduced approach for every iteration based on the nature of the dataset. It iterates until all frequent itemsets of various length are discovered. The detailed process of finding frequent itemsets of I length for the transactional dataset is outlined in Algorithm 2.
For Ith iteration, a basic condition (a large number of frequent itemsets in recent iteration) is checked which depends on the number of items frequent in (I1) iteration. If the condition is satisfied, then Reduced approach is used. Singleton frequent items are stored in a Bloom filter. The input file is broadcasted to every worker node to make it available locally to each worker. Subsequently, a flatMap function is applied on every transaction in dataset (line 2). Mapper takes each transaction and prunes it so that it contains only items which exist in the Bloom filter. Mapper yields all possible pairs for the pruned transaction as \(\langle key, value \rangle\) pairs where key denotes every pair in the pruned transaction and value is an integer 1 (lines 4–6). Subsequently, a reduce task combines all pairs according to the key (reduceByKey function) and filter out the results having value less than minimum support (lines 8–9). At last, results are stored in a SparkRDD.
Example
Figure 4 shows an example of frequent pair itemsets generation step. For 2nd iteration, the approximate cost of reduced and conventional approach is calculated using the size of the frequent set in the first phase and dataset size. The reduced approach is used if the condition is satisfied. A transactional database stored on HDFS and singleton frequent itemsets stored in Bloom filter are treated as the input. The mappers in the first round receive a set of transactions (e.g. mapper MAP1 receives transaction T1–T2) and they prune each transaction so that it contains only items which exist in the Bloom filter. For example, transaction T1 (S, R, M) is mapped to pruned transaction T1 (S, R).Now, mappers yield all possible \(\langle key, value \rangle\) pairs for the pruned transaction. For example, pruned transaction T1 (S, R) is mapped to \(\langle SR, 1 \rangle\). Subsequently, a reduce task combines all pairs according to the key (reduceByKey function) and filter out pairs having value less than two. At last, results are stored on SparkRDD.
If the cost of conventional approach is less than reduced, then conventional approach is used for pair generation. A transactional database stored on HDFS and a hash tree having candidate set (\(\langle SR \rangle\), \(\langle SG \rangle\), \(\langle SP \rangle\), \(\langle RG \rangle\), \(\langle PG \rangle\), \(\langle RP \rangle\)) are treated as the input. The mappers in the first round receive a set of transactions (e.g. mapper MAP1 receives transaction T1–T2) and they find each kitemset for each transaction and generate corresponding \(\langle key, value \rangle\) pairs. For example, transaction T1 (S, R, M) is mapped to \(\langle SR, 1 \rangle\). Subsequently, a reduce task combines all pairs according to the key (reduceByKey function) and filter out pairs having value less than two. At last, results are stored in SparkRDD.
Adaptiveness of the algorithm comes from the test for the condition as follows. Let us assume that there are X transactions, M mappers, g average number of elements in every transaction and f number of items frequent after the last iteration. Further, t is time to search an element in HashTree, and b is time taken to search an element in bloom filter.

Time complexity to generate candidate set = \((I+1)C^{f}_{I}\)

Time complexity to store candidate set in HashTree = \(I*C^{f}_{I}\)

Time complexity to search and yield pairs = \(\frac{X}{M}*tg\)

Total time complexity for conventional approach = \((2I+1)(C^{f}_{I}) + \frac{X}{M}*tg.\)

Time complexity to store singleton frequent items in Bloom filter = f

Time complexity to make pruned transaction = \(\frac{X}{M}*g\)

Time complexity to generate pairs in worst case = \(\frac{X}{M} * C^{g}_{I}\)

Total time complexity for reduced approach = \(f + \frac{X}{M} * (C^{g}_{I} + g).\)
I, t and b are constant values mainly less than 10 and number of transactions are in millions for large datasets. Therefore, they are nearly negligible in term of complexity. After removing these final term will be \((C^{f}_{I} + \frac{Xg}{M}) >= (\frac{X}{M} * C^{g}_{I})\)
Number of frequent itemsets in last iteration (f) or candidate set size (candidate set size = \(\frac{f(f1)}{2}\)) and average number of items (g) in a transaction are main attributes in above condition. Reduced approach will be more useful if either f is high or g is small.
For an iteration I, to use reduced approach the condition \((C^{f}_{I} + \frac{Xg}{M}) >= (\frac{X}{M} * C^{g}_{I})\) must be satisfied. If the given condition is satisfied then complexity of conventional approach will be greater than reduced approach. Therefore, AdaptiveMiner will make decision to choose the reduced approach instead of conventional approach.
Evaluation
In this section, AdaptiveMiner’s performance is evaluated in comparison to YAFIM and RApriori on spark. 1st iteration of all algorithms is same so computation time depends on the platform used. Remaining iterations are the main concern in perspective of performance. All experiments were executed four times, and average results were taken as a final result.
Cluster and dataset
The performance of AdaptiveMiner is evaluated on a cluster having 5 nodes where each node has 24 cores and 64 GB RAM. All computing nodes are running on Ubuntu 14.04 LTS operating system. Oracle Java 8 is used to build the project. Spark 1.5.2 and Hadoop 2.6 are used to run AdaptiveMiner.

Performance evaluation

For T10I4D100K dataset, AdaptiveMiner performs better than Apriori and same as RApriori for 2nd iteration, but it performs same as both Apriori and RApriori for 3rd and 4th iterations (Fig. 6a).

For T25I10D10K dataset, AdaptiveMiner performs better than Apriori and same as RApriori for 2nd iteration, but it outperforms RApriori also for 3rd iteration. For 4th iteration again all use same candidate set approach due to less number of frequent items in 3rd iteration (Fig. 6b).

For Retail, AdaptiveMiner is better than Apriori but same as RApriori for all iterations because number of items after 2nd iteration is less and it uses candidate set approach when the number of frequent items in the last iteration is small (Fig. 7a).

For Musroom dataset, AdaptiveMiner performs better than RApriori and same as conventional Apriori for 2nd iteration because number of singleton frequent itemsets are very less so AdaptiveMiner uses candidate set approach for 2nd iteration. Hence AdaptiveMiner is always performing better or same as Apriori and RApriori (Fig. 7b).

For Kosarak dataset, AdaptiveMiner performs better than Apriori and same as RApriori for 2nd iteration, but it outperforms RApriori also for 3rd and 4th iteration (Fig. 8a).

For BMSWebView2 dataset, AdaptiveMiner performs better than Apriori and same as RApriori for 2nd iteration, but it performs same as both Apriori and RApriori for 3rd and 4th iterations (Fig. 8b).
Conclusions
A Spark based distributed algorithm AdaptiveMiner is implemented to mine frequent patterns from large datasets. It uses a new modified approach (Adaptive) as well as basic Apriori theorem that an itemset is frequent only if all its nonempty subsets are frequent. The reduced approach will be used when number of frequent itemsets in last iterations are large, otherwise basic Apriori approach will be used. AdaptiveMiner makes execution plans before every iteration and computes the cost for every execution plan. Execution plan with minimum cost is used to get results for that iteration. This dynamic approach of taking decision for every iteration during runtime makes AdaptiveMiner very fast and efficient. It is implemented on Apache Spark platform which provides it highly parallel and distributed computing environment. Spark is best suited for AdaptiveMiner because it has support for inmemory distributed computation. Results on various standard datasets show that AdaptiveMiner outperforms existing MapReduce based distributed algorithms. AdaptiveMiner performs better or same as conventional Apriori and RApriori for every iteration for every large dataset. AdaptiveMiner is available on GitHub for download and use.
Future work
Apache Flink has shown great performance for iterative computations in recent few years. It provides native support for iterative computations. AdaptiveMiner is an iterative algorithm. Therefore, we will implement AdaptiveMiner on Flink to check performance in comparison to Spark implementation in future.
