Description

Preprocessing: Instance-wise normalization to mean zero and variance one. Then feature-wise normalization to mean zero and variance one. The original dataset consists of 49 instances. Five are removed since the classification results using immunohistochemistry and protein immunoblotting assay confilcted. Of the remaining, two instances were rejected due to failed array hybridization. The rest data are further splited into training (38), and validation (4).
