Machine Learning Resources

For musical and artistic creative application, Rebecca Fiebrink's Wekinator is recommended as a first step in implementing ML. This is great for bypassing the usual painful and predictable mapping required in traditional interactive design. She also provides a free course on Wekinator and ML generally.

I found that the best (and free!) way to learn more deeply about ML and implementing Tensorflow is starting with the Google Colab crash course.
