He's mentioned tensor flows and machine learning in his work before.

He also has an implementation called New Harmony written in Julia you can mess with.

Oh yeah, and the ML stuff would never replace raw gaussian elimination. It's just more time efficient if you know what end state you're looking for. It would just be a tool for planners, not a planning system. Kinda like when you have render previews in 3D modeling software to get a general idea of what you need to add to make a scene lol right.
