Building a Language and Compiler for Machine Learning
As someone who works in merging differential equations and machine learning, I have found this kind of work essential for what I do. Pervasive AD that allows merging neural networks and diffeq solvers is allowing us to explore all of kinds of new models and new problems. Sure it doesn't impact vanilla machine learning all that much (though Zygote.jl does allow for a lot of optimizations that wouldn't be possible with tracing-based AD), but it definitely opens up a new wave of AI possibilities.
