22 tests passing, and my solver still told you to click a mine

I wrote a minesweeper probability solver. You hand it a board, it hands back the probability that each unknown square is a mine, so that when logic runs out and you have to guess, you at least guess the cheapest square. It has 22 unit tests. They all pass. I also cross-checked it against an indepen...

Embeddings: Meaning as Numbers

When you ask a chatbot for a pasta recipe, it doesn’t understand “pasta” the way you do. It sees a list of numbers. Those numbers are not random. They are arranged so that “pasta” sits close to “spaghetti” and far from “car.” This is an embedding. It turns meaning into coordinates that a machine can...
