Neural networks for music: a journey through its history

Post written in collaboration with and sponsorship of Exxact (@Exxactcorp).

Many things have happened between the pioneering papers written by Lewis and Todd in the 80s and the current wave of GANs composers. Along that journey, connectionists’ work was forgotten during the AI winter, very influential names (like Schmidhuber or Ng) contributed seminal publications and, in the meantime, researchers have made tons of awesome progress.

I won’t be going through every single paper in the field of neural networks for music nor diving into technicalities, but I’ll cover what are the milestones that helped shaping the current state of music AI – this being a nice excuse to give credit to these wild researchers who decided to care about a signal that is nothing else but cool. Let’s start!

ISMIR article: End-to-end learning for music audio tagging at scale

Our accepted ISMIR paper on music auto-tagging at scale is now online – read it on arXiv, and listen to our demo!

TL;DR:
1) Given that enough training data is available: waveform models (sampleCNN) > spectrogram models (musically motivated CNN).
2) But spectrogram models > waveform models when no sizable data are available.
3) Musically motivated CNNs achieve state-of-the-art results for the MTT & MSD datasets.
