Feature Selection is one of the core concepts in machine learning and has a high impact on the performance of the model. Irrelevant or partially irrelevant features can negatively impact the model performance. In this process, those features which contribute most to the prediction variable are ...
High-dimensional data analysis is a challenge for researchers and engineers in the fields of machine learning and data mining. Feature selection provides an effective way to solve this problem by removing irrelevant and redundant data, which can reduce computation time, improve learning accuracy, and...

— Dikran Marsupial in answer to “Feature selection for final model when performing cross-validation in machine learning” The reason is that the decisions made to select the features were made on the entire training set, that in turn are passed onto the model. This may cause a mode a mode...
A central problem in machine learning is identifying a representative set of features from which to construct a classification model for a particular task. This thesis addresses the problem of feature selection for machine learning through a correlation based approach. The central hypothesis is that go...
