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 |
