Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers link Mike X Cohen's Substack for posts on the math behind word embeddings, such as the 'king - man + woman = queen' analogy. The only comment links a post on that topic while asking about linear operations in embeddings.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
Isn't the whole linear operations thing not really true and even less so now in embeddings from transformer based models? I remember reading a blog about this but cannot find it anymore. This is the closest thing i could find now: https://mikexcohen.substack.com/p/king-man-woman-queen-is-fa...
