GenMiner

Genomic Data Miner

Description

Java implementation of the GenMiner algorithm for mining equivalence classes and minimal non-redundant association rule from gene expression data.

The software, distributed as an executable JAR file with graphic user interface, integrates the R implementation of the Normalized Discretization method (Nordi) to preprocess gene expression data and a Java implementation of the frequent closed itemsets based algorithm to extract equivalence classes and minimal non-redundant association rules from these data.

Experimental Results

These results were obtained from the annotations enriched Eisen et al. dataset containing integrated gene expression measures for 2465 Yeast genes and 737 columns (79 discretized gene expression levels and 658 gene annotations). 

The gene expression measures were discretized by the Nordi algorithm with a 95% confidence level. The minimal confidence threshold was set to 50% and the minimal support threshold was set to 0.3% (association rules extracted correspond to at least 7 genes).
