NNCP: Lossless Data Compression with Neural Networks (2019)
Compression speed is around 2 KB/sec.<p>The figure is given in nncp_v2.1.pdf. This is 1000x slower than xz, which in turn is 1000x slower than gzip.<p>I have always wondered if a compression <i>service</i> 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 <i>really</i> 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 -<p><pre><code>    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.
