Normal tissue and cancer type classification based on chromosome arm-wide gene expression levels. a K-Nearest-Neighbors (KNN) multi-class analysis: predictions made in a leave one out fashion (i.e., the accuracy). Height of bars indicates the fraction of correctly predicted cases. The numbers on top of each bar indicate the number of samples available for each class. b, c t-Distributed Stochastic Neighbor Embedding (t-SNE) dimensionality reduction analysis of chromosome arm-wide mean gene expression levels in normal tissues (b) and in cancers (c)
