The Mystical Art of Cosine Similarity: A Guide for the Terminally Confused
In yet another groundbreaking exposition, tomhazledine.com takes us deep into the bewildering world of vectors, or 'embeddings' if you prefer sounding smarter at cocktail parties. Here, we learn that 'cosine similarity' isn't just a fancy term you drop to impress a date but indeed involves angles and math, shocking legions of commenters who had blissfully avoided trigonometry since high school. One brave soul attempts to demystify the concept by reducing it to 'the sum of term-by-term products of normalized vectors', essentially describing every math problem ever but with more steps. Meanwhile, the rest of the peanut gallery battles over whether this is geometry or just a desperate cry for help from people who see vectors in their sleep.
