Non built-in sklearn models to concrete

Is it possible to convert any sklearn-model to concrete via ONNX? I stumbled over this page in version 0.2 (Hummingbird Usage - Concrete ML) but can’t find anything in the current version. I would really like to use OneClassSVM or an IsolationForest

Thanks in advance for any input :slight_smile:

Hello @lstk,
Unfortunately, this is not currently possible in Concrete ML. Usually, scikit-learn models require specific managements which prevents us from having an automatic way to convert them. Basically, both OneClassSVM and IsolationForest models will need to be manually integrated in the library.

Nonetheless, if you are interested by doing so yourself, let me know ! We could try to see if that could fit in our bounty program.

Thanks for asking !
