I looked into adding LARS into MLJLinearModels but it’s a bit of a different beast in that all models in MLJLM (currently) correspond to an optimisation problem of the form min (Loss+Penalty). afaiu LARS is not like that (kindly correct me if I’m wrong).
I’d still be in favour of expanding MLJLM and LARS (or stuff like RANSAC) seem like good candidates, happy to brainstorm that somewhere with people keen to gather such models in one spot.
