DescriptionExample of Targeted Projection Pursuit.gif |
English: In this example targeted projection pursuit is being used to explore projections of a gene expression data set. Each of the 122 points corresponds to a sample taken from a cancer tumor of four diagnostic classes (represented by color). For each sample, the expression level of 100 genes was recorded (represented by the axes). The animation shows that TPP is able to separate two of the classes clearly (red and purple), but two others could not be distinguished (blue and green). The position of the axes then indicates teh activation of which genes are most associated with each class. |
