WebMay 3, 2015 · Feature selection doesn't reduce amount of data but reduces number of features. The number of instances (samples) remains the same, and it can help to overfitting because, the classifier needs fewer parameters (if it is a parametric model) to fit the data. Fewer parameters mean less representation power, so less likely to overfit.
