Fine-Grained Classroom Activity Detection from Audio with Neural Networks

1 code implementation29 Jul 2021 Eric Slyman, Chris Daw, Morgan Skrabut, Ana Usenko, Brian Hutchinson

We obtain strong results on the new fine-grained task and state-of-the-art on the 4-way task: our best model obtains frame-level error rates of 6. 2%, 7. 7% and 28. 0% when generalizing to unseen instructors for the 4-way, 5-way, and 9-way classification tasks, respectively (relative reductions of 35. 4%, 48. 3% and 21. 6% over a strong baseline).
