Bolt: Faster matrix and vector operations that run on compressed data

If your data is represented as sparse vectors, that sparse representation is already compressed. You wouldn’t want to decompress it to a dense representation just to apply a different, less effective, lossy compression algorithm. That would be like taking a screenshot of a paragraph of text so you can post a JPEG of it to Twitter.

Oh, wait.

Exactly. You can run it on sparse inputs. It's just that our implementation doesn't exploit the sparsity, so we don't claim that it will work better.
