NNCP: Lossless Data Compression with Neural Networks (2019)
Compression speed is around 2 KB/sec.The figure is given in nncp_v2.1.pdf. This is 1000x slower than xz, which in turn is 1000x slower than gzip.I have always wondered if a compression service could be a viable commercial offering and with NNCP rates and its compression speed, it looks like it could! That's for cases when you need to really compress the heck out of something, e.g. prior to distributing a large static piece of data to a very large number of recipients. I think there was a service like this, used by AAA game developers for distributing patches, but it didn't take because it had a very slow decompression... and, now reading further through the paper, it looks like an issue with NNCP too -    The NNCP v2 decompression speed is similar to its compression speed.

So it's a no-go for my brilliant and lazy startup idea, but fascinating stuff nonetheless.
