I actually found this product most interesting, perhaps oddly, for voyaging far afield from the fashion preference. Picture leads to books leads to toys leads to ... a television that emits heat like a fireplace. I actually kind of want a television that emits heat / cold in response to what's on television (the product was just a tv fireplace that made heat). Notably, like others have pointed out, and the author alr…

The "shop for random products" direction was actually fun for me too. Reminds me of amazon.com/stream a bit.

Out of curiosity, what's the size of vectors you're using (# of dimensions) and what distance metric are you using? Euclidean?

To optimize for fast nearest neighbors, I chose 256 dims. Notably, this actually hurt some of the pre-training classification losses pretty severely compared to 2k dims, so it definitely has a quality cost.

The site uses cosine distance. The code itself implements Euclidean distance, but I decided to normalize the vectors last minute out of FUD that some unusually small vectors would appear as neighbors for an abnormal number of examples.
