So I'm working with the UrbanSound 8k set on Kaggle.

I want to try two approaches:

  • MFCCs and Mels for image classification.
  • Raw audio data classification.

Would a 1DCNN work for both approaches?

Hey, I'm new at ML and I have a question. I've created a LSTM and XGBoost model etc, trained it, evaluated it etc. But now, how do I actually forecast future data ? Do you have a notebook where the creator actually plot predictions? I can't seem to find one !

I'm not actually sure. I've just been chatting with people in an unrelated Discord's off topic channel about it.

I'd post some of what I've got from it but I have no idea what I'm doing with it and don't think what I'm getting would be decently representative of what it can actually do.

There was a paper about it. There was a find - specific set of positions not encountered or pooply represented during self-play. Fully trained AlphaGo was failing on those positions. However then they were explicitly added to the training set the problem was fixed and AlphaGo was able to play them well. This adversarial traning seems just an automatic way to find those positions.

PS fintess landscape is not convex it separated by hills and valleys. Self-play may have a problem in reaching all important states.
