scikit-mlm is a Python module implementing the Minimal Learning Machine (MLM) machine learning technique using the scikit-learn API.

the scikit-mlm package is available in PyPI. to install, simply type the following command:

pip install scikit-mlm

• you may need to use the --user flag for the commands above to install in a non-system location (depends on your environment). alternatively, you can execute the pip commands with sudo (not recommended).
• you may need to add the --use-wheel option if you have an older pip version (wheels are now the default binary package format for pip).

example of classification with the nearest neighbor MLM classifier:

from skmlm import NN_MLM
from sklearn.preprocessing import MinMaxScaler
from sklearn.model_selection import cross_val_score
from sklearn.pipeline import make_pipeline
from sklearn.datasets import load_iris

# load dataset
dataset = load_iris()

clf = make_pipeline(MinMaxScaler(), NN_MLM(rp_number=20))
scores = cross_val_score(clf, dataset.data, dataset.target, cv=10, scoring='accuracy')

print('AVG = %.3f, STD = %.3f' % (scores.mean(), scores.std()))

if you use scikit-mlm in your paper, please cite it in your publication.
