Join me for a meander down linear-algebra lane

I’m gonna do something different: I’m not going to talk about AI.

Some tips from someone who's done it (sort of)

A data challenge a day helps you master machine learning

On analogies and arithmetic inside LLM embeddings spaces.

Do lines even exist outside our imaginations?
