Congratulations Ethan! Ethan has done great works in MIR and Machine Learning during his remarkable PhD time. I always enjoy working with Ethan, and I learned a lot from him!

Hey y'all, my dissertation was quietly put up online a few weeks ago and I wanted to highlight some parts of it that I was particularly proud of... 1/10

For the contrastive learning model we build a contrastive learning model with HTSAT audio encoder and Roberta text encoder. With the large-scale dataset and input fusion, our performs well on text-audio retrieval tasks, as well as down-stream tasks. 4/6

The audio files collected from the internet have variable duration, making it insufficient to learn with a fixed-length encoding model. We adapted feature fusion to the audio encoder to enable the audio encoder to have a fixed compute given any input length. 3/6

Audio data is often more expensive to collect and annotate, which makes the audio dataset often smaller than the image counterparts. In this work, we announce LAION-Audio-630K, 630k text-audio pairs collected from the internet. 2/6

What’s exciting about the CEG is that it uses a set of structured generative models which provide annotations for many music machine learning applications like automatic music transcription, multi-f0 estimation, source separation, performance analysis, and more! 🧵

We trained an automatic music transcription model MT3 on URMP and CocoChorales. Compared to training on only URMP that our data generator trains on, we get big improvement. This suggests using generate models to generate data helps task performance on low-resource dataset. 🧵

As its name suggests, the Chamber Ensemble Generator (or CEG) can generate performances of chamber ensembles playing in the style of four-part Bach chorales. We call the generated dataset CocoChorales Dataset, and it has 240,000 examples totaling over 1,400 hours of mixture data.

Our answer: the model itself! We combined two structured generative models–a note generation model, Coconet, and a notes-to-audio generative synthesis model, MIDI-DDSP–into a system we call the Chamber Ensemble Generator. 🧵

Modern machine learning systems require large quantities of *annotated* data. With music systems, getting annotations requires tedious work by expert musicians. How can we easily annotate hundreds of thousands of examples to make enough data to train a machine learning system? 🧵
