Other Distance Metrics

[shancarter]

Is it possible to use something like angle (cosine similarity) as the measure of closeness?

Thanks for the suggestion.

Since ANNOY supports Euclidean distance, Manhattan distance, cosine distance, Hamming distance, and Dot (Inner) Product distance, it is possible to add other distance measures. I will add this soon in the next update.

Awesome, thanks for the quick response!

I added the Manhattan, angular (i.e. cosine), and Hamming distances.

Wow, thanks!
