This small cost comes from wasting some of the probability mass in the relevant Q distributions. In other words, the SNE cost function focuses on retaining the

An Introduction to Variable and Feature Selection

jmlr.csail.mit.edu

outside of the scope of machine learning, so we focus here on building predictors. We consider in this section ranking criteria defined for individual variables, independe ntly of the context of others. Correlation methods belong to that category. We also limit ourselves to supervised learning criteria.

Van der Waals (VDW) interactions are probably the most basic type of interaction imaginable. Any two molecules experience Van der Waals interactions. Even macroscopic surfaces experience VDW interactions, but more of this later. The physical process that leads to Van der Waals interactions is clear, but it is difficult to
