Ya sure… so the objective is to minimize the number of documents humans hav to label. Which means the system needs to lesrn while the humans are labelling and paralelly check its prediction accuracy and have a confidence measure that needs to be really high if humans were to accept the machine’s labels.

@anamariapopescug Any luck on this?

I am looking to implement active learning for text classification/image classification where instead of re-training manually after a period, we allow the model to learn from manually tagged data as and when the tagging is being done. Is there a way to do this currently?

@jeremy, your suggestions on this?
