With this data set we address the classification problem of distinguishing patients with breast cancer according to there response to neoadjuvant docetaxel treatment (patients can be resistant or sensitive to the treatment). The samples were obtained before treatment and the tumor response to neoadjuvant treatment was later assessed.
Platform: Affymetrix GeneChip Human Genome U95 Version [1 or 2] Set HG-U95A
Diagnostic classes:
- resistant to docetaxel treatment (resistant): 14 examples (58.3%)
- sensitive to docetaxel treatment (sensitive): 10 examples (41.7%)
Number of genes: 12625 Number of samples: 24
Predictive accuracy with 10-fold cross validation (classifying using the best projection with eight attributes):
Following are the three best-ranked visualization with eight, six and four attributes in respect to the visualization score, that is, visualizations where examples from different diagnostic classes are best separated:
