DOI: 10.1021/ci060003g

Installation

pip install ModifiedNB

Usage

Works exactly like any other scikit-learn model.

import numpy as np
X = np.random.randint(5, size=(6, 100))
y = np.array([1, 2, 3, 4, 5, 6])

from ModifiedNB import ModifiedNB
clf = ModifiedNB()
clf.fit(X, y)
# generate KNIME/PP like scores
clf._joint_log_likelihood(X)[:,1]
