Yeah, LightOn has been doing this for years already, it's kind of strange that there was no mention of them in the article. I know them because their offices are close to the research center where I work (in Paris, France). If I'm not wrong they were planning to offer their optical processor as a cloud service too.

fyi the founder Igor Carron runs a pretty nice academic blog on compressive sensing (a bit less academic in recent months)

Also hosts the advanced matrix factorization jungle website which is a nice browse if you're interested in mf techniques.

I remember that blog from when I was studying penalty/regularization methods over a decade ago. Was a great source of interesting papers and ideas.

You might be well informed in compressive sensing:

What's the status of the compressive sensing research, and commercialization if there is any?

his presentation on LightOn is pretty interesting https://www.youtube.com/watch?v=0QtY4_UJF0w&ab_channel=Light...

It looks like their rack mounted 2U sized device does up to 1900 dense matrix mps.

Would you happen to know how that would compare to a typical (I guess mid-range) server for AI? I'd like to get a sense of the magnitude of improvement offered.
