extract latent features from ALS

[ChristelSwift]

hi there, is there a way to extract the resulting matrices (ie latent features) from the ALS implementation?

The latent model is learned in the current implementation during prediction. This is why you cannot extract it from the model. A better implementation that learns the model and then folds in new data would be great, but we need someone to implement it.
