<div dir="ltr">We have definitely discussed association rules in issues before. It's considered out of scope for scikit-learn, except insofar as it is used for learning classification. We haven't yet been convinced that classifiers based on associative learning have enough practical demand to justify their maintenance in the project. Then again, we have not had a pull request implementing any such algorithms; there seems to be demand mostly for the vanilla association rule mining algorithms. They are definitely out of scope for scikit-learn.<div><br></div><div>See: <a href="https://github.com/scikit-learn/scikit-learn/issues/801">https://github.com/scikit-learn/scikit-learn/issues/801</a>, <a href="https://github.com/scikit-learn/scikit-learn/issues/2662">https://github.com/scikit-learn/scikit-learn/issues/2662</a>, <a href="https://github.com/scikit-learn/scikit-learn/issues/2872">https://github.com/scikit-learn/scikit-learn/issues/2872</a></div>​</div>
