A Review of Feature Selection and Feature Extraction Methods Applied on Microarray Data

Table 3

Advantages and disadvantages between feature selection and feature extraction.

Method	Advantages	Disadvantages
Selection	Preserving data characteristics for interpretability	Discriminative power
		Lower shorter training times
		Reducing overfitting
Extraction	Higher discriminating power	Loss of data interpretability
	Control overfitting when it is unsupervised	Transformation maybe expensive
