projects, ga, jax
rather than use all 13 channels in a multi spectral image for classification can we train a model that is robust to all combos, at all resolutions, and use a genetic algorithm to choose which are the most valuable?
tpu, ensemble_nets, jax, projects, haiku
a 4 (and a bit) part tutorial / colab / screencast series starting with jax fundamentals working up a data parallel approach to running on a cloud tpu pod slice... all focused on solving the toughest problem in machine learning; 1d y=mx+b
