Besides the resources in our article, we are aware of libraries like modAL, ALiPy, or libact as active learning frameworks. Interfaces to collect, correct and revise feedback are rare. In addition, to the general framework, on how to use Active Learning in production, we visualize how we retrieve feedback from subject matter experts/users.

Disclaimer: The first half of the article provides a general framework how to use Active Learning in production. In the section "How does Active Learning work in practice?" we visualize how we implemented active learning in production using our OCR & Document AI platform. Some people might feel the latter part promotional that we add this disclaimer.

Feel free to add comments on "How are you using active learning in production?"
