When feature selection is applied to these datasets to identify the most important features, the biases inherent in some multivariate feature selectors due to correlated features make it difficult for these methods to distinguish between the important and irrelevant features and the results of the feature selection process can be unstable.

A fixed threshold, which is typically applied, offers no guarantee that the final set of selected features contains only relevant features.
