When data mining techniques are applied to discover useful knowledge behind a large data collection, they are required to be able to preserve some confidential information, such as sensitive frequent itemsets, rules and the like. A feasible way to ensure the confidentiality is to sanitize the database and conceal sensitive information. However, the sanitization process often produces side effects, thus minimizing these side effects is an important task.

Batch incremental SNN-DBSCAN clustering algorithm
Incremental data mining algorithms process frequent up- dates to dynamic datasets efficiently by avoiding redundant computa- tion. Existing incremental extension to shared nearest neighbor density based clustering (SNND) algorithm cannot handle deletions to dataset and handles insertions only one point at a time. We present an incremen- tal algorithm to overcome both these bottlenecks by efficiently identify- ing affected parts of clusters while processing updates to dataset in batch mode. -

aprioriProcess
Apriori is designed to operate on databases containing transactions.
The Apriori Algorithm is an influential algorithm for mining frequent itemsets for boolean association rules. Key Concepts : • Frequent Itemsets: The sets of item which has minimum support (denoted by Li for i th -Itemset). • Apriori Property: Any subset of frequent itemset must be frequent. • Join Operation: To find Lk , a set of candidate k-itemsets is generated by joining Lk-1 with itself. -

graph mapping distance matrix generator
parallel REAFUM code
We propose a parallel algorithm to do representative approximate frequent subgraph mining based on the REAFUM algorithm in this project. We successfully apply Fork-Join Model to our algorithm and parallelize the calculations on the generation of graph mapping distance matrix. Our algorithm guarantees identical results with REAFUM given same input while achieving significant improvements in runtime when running with multi-threads. -

LTS: Learning to Search
Discriminative subgraph mining by learning from search history
LTS (Learning to Search) is an implementation of an algorithm described in "LTS: Discriminative Subgraph Mining by Learning from Search History" in Data Engineering (ICDE), IEEE 27th International Conference, pages 207-218, 2011. The purpose of LTS is to find discriminative subgraphs, which are smaller graphs that are embedded in larger graphs that all share a certain trait. A discriminative subgraph can help to characterize a complex graph and can be used to classify new graphs with unknown traits. ... -
