Combining 3 feature selectors
We'll combine the votes of the 3 models you built in the previous exercises, to decide which features are important into a meta mask. We'll then use this mask to reduce dimensionality and see how a simple linear regressor performs on the reduced dataset.
The per model votes have been pre-loaded as lcv_mask
, rf_mask
, and gb_mask
and the feature and target datasets as X
and y
.
