Correlation-based Feature Selection for Machine Learning
Further experiments compared CFS with a wrapper—a well know n approach to feature selection that employs the target learning algorithmto evaluate feature sets. In many cases CFS gave comparable results to the wrapper, and in general, outperformed the wrapper ... 4 Correlation-based Feature Selection 51

hassenfeld.bryant.eduPositive correlation is when you observe A increasing and B increases as well. Or if A decreases, B correspondingly decreases.
