Most important features Gaussian Naive Bayes classifier python sklearn












1















I am trying to get the most important features for my GaussianNB model. The codes from here How to get most informative features for scikit-learn classifiers?
or here How to get most informative features for scikit-learn classifier for different class? only work when I use MultinomialNB. How can I calculate or retrieve the most important features for each of my two classes (Fault = 1 or Fault = 0) otherwise?
My code is: (not applied to text data)



df = df.toPandas()

X = X_df.values
Y = df['FAULT'].values.reshape(-1,1)


gnb = GaussianNB()
y_pred = gnb.fit(X, Y).predict(X)

print(confusion_matrix(Y, y_pred))
print(accuracy_score(Y, y_pred))


Where X_df is a dataframe with binary columns for each of my features.

  • That's the example I cited: it only works for Bernoulli or Multinomial but not Gaussian
