This document analyzes and compares several algorithms for frequent itemset mining on different datasets, including Apriori, FP-Growth, H-mine, and P-Hmine. It describes applying these algorithms to the mushroom dataset, which contains descriptions of mushroom species, and the chess dataset. It finds that FP-Growth performs best on dense datasets due to its compact FP-tree structure, while H-mine is better for sparse datasets. P-Hmine and H-mine outperform Apriori by requiring fewer scans of the database.
Weighted frequent pattern mining is suggested to find out more important frequent pattern by considering different weights of each item. Weighted Frequent Patterns are generated in weight ascending and frequency descending order by using prefix tree structure. These generated weighted frequent patterns are applied to maximal frequent item set mining algorithm. Maximal frequent pattern mining can reduces the number of frequent patterns and keep sufficient result information. In this paper, we proposed an efficient algorithm to mine maximal weighted frequent pattern mining over data streams. A new efficient data structure i.e. prefix tree and conditional tree structure is used to dynamically maintain the information of transactions. Here, three information mining strategies (i.e. Incremental, Interactive and Maximal) are presented. The detail of the algorithms is also discussed. Our study has submitted an application to the Electronic shop Market Basket Analysis. Experimental studies are performed to evaluate the good effectiveness of our algorithm..

Literature Survey of modern frequent item set mining methodsijsrd.com
In this paper, we present an overview of existing frequent item set mining algorithms. All these algorithms are described more or less on their own. Frequent item set mining is a very popular and computationally expensive task. We also explain the fundamentals of frequent item set mining. We describe today's approaches for frequent item set mining. From the broad variety of efficient algorithms that have been developed we will compare the most important ones. We will systematize the algorithms and analyse their performance based on both their run time performance and theoretical considerations. Their strengths and weaknesses are also investigated. It turns out that the behaviour of the algorithms is much more similar as to be expected.

Parallel Key Value Pattern Matching Modelijsrd.com
Mining frequent itemsets from the huge transactional database is an important task in data mining. To find frequent itemsets in databases involves big decision in data mining for the purpose of extracting association rules. Association rule mining is used to find relationships among large datasets. Many algorithms were developed to find those frequent itemsets. This work presents a summarization and new model of parallel key value pattern matching model which shards a large-scale mining task into independent, parallel tasks. It produces a frequent pattern showing their capabilities and efficiency in terms of time consumption. It also avoids the high computational cost. It discovers the frequent item set from the database.
Basically, I don't give any description but I want to tell you that I made this PPT with my crush. That's why it is my first PPT which I can upload on slide share.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

2. Contents
• Introduction
• Association rule mining
• Frequent itemset mining and Algorithms for data model
• Algorithms:
• Apriori
• FP-Growth
• H-mine
• P-Hmine
• Conclusion
3. Introduction
• In this paper a complete description of the dataset mushroom is
described on hypothetical samples corresponding to different
species of mushrooms.
• The dataset consists of 8124 instances of 119 attributes which are
derived from 24 species.
• So this is checked by different algorithms which discussed the
datasets of mushroom.
4. Association rule mining
• Process of discovering
relationship among the data
items in large data base.
• It is one of the most important
problem in the data mining.
• Finding frequent itemset is one
of the most computationally
expensive tasks in association
rule mining.
5. Frequent itemset mining representations
Follows are the methods of
representation of databases:
1. Horizontal representation
2. Vertical representation
3. Bit-vector representation
8. Apiori
• In preprocessing of apriori algorithm the scane of database is
performed to find out support count of each item then all these
whose minimum is less are removed from the database.
• Aprori follows two step method to find out frequent itemset that
is :
• Join step
• Prune step
10. FP-Growth
• FP-Growth is known as one of the fastest algorithm of frequent set
mining.
• it uses a compact Data Structure called a FP-tree.
• FP-growth approach first represent the frequent itemset in the
form of frequent pattern tree fp-tree which is compressed
structure
12. H-mine
• H-mine is another pattern growth method for frequent pattern
mining in Sparse data H-mine is better than it FP-growth.
• H-mine uses divide and conquer strategy to mine all the frequent
pattern
13. P-Hmine
• The general idea of P-Hmine is that is a represent the database in
the form of a new structure called P-Hstruct. which is similar to
H-struct.
• In P-Hmine struct we represent the database as a set of queues.
Experimental Analysis and Result
• We analyze the running time of algorithm running on both
synthetic and actual data, synthetic data sets generator is taken
from IDM Almanden website.
14. Datasets
• The data set mushroom is a description of hypothetical sample
was corresponding to different species of Mushrooms.
• The dataset consists of 8124 instances of 119 attributes which are
derived from 24 species.
• The chess data set is also a dense datasets that is consist of 3196
instances and 74 itemset.
15. Conclusion
• Conclusion in this paper h-mine for uncertain data. Finally we
have analyzed the performance of frequent pattern mining
algorithm on few benchmark metrics.
• In case of binary dense data model FB-growth performs better
than other algorithms because the dense dataset result in a very
compact FP-tree which requires less amount of data.
16. Continue…
• In case of sparse data sets H-mine performs better than FP-
growth. The reason is that the FP-tree is bigger and spend a lot of
time in building and transversing the conditional FP-trees.
• The Hmine and P-Hmine saved a lot of scans of the database and
achieve better performance than Apriori on all tested datasets.
• The P-Hmine is also scalable for both large number of data items
and large number of transactions.
