Given the joint feature-label distribution, increasing number of features always results in decreased classification error; however, this is not case when a classifier designed via rule from sample data. Typically (but always), for fixed size, error decreases and then increases as grows. The potential downside using too many most critical small samples, which are commonplace gene-expression-based classifiers phenotype discrimination. For size issue to find an optimal features.Since only rare...
