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.
