Data set name: GSE2685

Brief description:

In the second model of the gastric cancer data set (GSE2685) we combined the diffuse and intestinal advanced gastric tumor samples into one class in order to distinguish cancer from noncancerous samples based on gene expression measurements.

Platform: Affymetrix GeneChip Human Full Length Array HuGeneFL

Diagnostic classes:

- Normal gastric tissue (Normal): 8 examples (26.7%)

- Advanced gastric cancer tissue (Tumor): 22 examples (73.3%)

Predictive accuracy with 10-fold cross validation (classifying using the best projection with eight attributes):

Classification accuracy: 93.33%

Area under curve (AUC): 0.915
