0.8.0

Description

✨ New Features

• MaximumRelevanceMinimumRedundancy feature selector #622 by @fabioscantamburlo
• HierarchicalPredictor, HierarchicalClassifier and HierarchicalRegressor #623 by @FBruzzesi

0.7.4

Added a new meta estimator for ordinal classification.

0.7.0

@FBruzzesi created a new OrdinalClassifier meta model. While somewhat experimental ... we can totally see how it may be nice for some folks. Enjoy!

0.7.0

Thanks to @FBruzzesi we now have new docs pages and an update to the DecayEstimator. This estimator is now more flexible, but does introduce a breaking change. Hence a big number update!
