MLFeatureSelection 0.0.8.2

Features selection algorithm based on self selected algorithm, loss function and validation method

General features selection based on certain machine learning algorithm and evaluation methods

Divesity, Flexible and Easy to use

More features selection method will be included in the future!

Quick Installation

pip3 install MLFeatureSelection

Modulus in version 0.0.8.2

• Modulus for selecting features based on greedy algorithm (from MLFeatureSelection import sequence_selection)

• Modulus for removing features based on features importance (from MLFeatureSelection import importance_selection)

• Modulus for removing features based on correlation coefficient (from MLFeatureSelection import coherence_selection)

• Modulus for reading the features combination from log file (from MLFeatureSelection.tools import readlog)
