Choose direction

Topics are everywhere.
Direction & Momentum is rare.
Pick any Vector

Every topic here has a direction. Pick a vector, follow it through its series, and go post by post until the thread runs out.

"A half-finished series teaches you less than a finished one taught badly. Pick a direction. See it through. That's how understanding compounds"

Models, data, and the math that makes them learn.
