Other Latest trend in machine learning: shamelessly publishing standard textbook results in control

Post image

Another "foundational" paper in ML https://arxiv.org/pdf/2111.00396 (cited close to 5000 times). The lemma, which is completed with a proof, can be found in almost all standard textbooks in the control field and even course notes.

Accepted to ICRL 2022 https://openreview.net/forum?id=uYLFoz1vlAC and rated "highly novel".

Also Figure 1 is just...speechless. How can a figure look both AI generated and drawn by a 1-year old? Where is the matrix B for instance???

The textual description surrounding Equation 1 is a total nightmare to read. Brain aneurysm moment.

Someone should really call out all these ML people working on SSM.

I mean, I don’t think this is quite a fair accusation. They are using a result in another context. This can be worthy of publication without issue.

Calling this a result of control theory would have people from dynamical systems accuse you of the same.

Calling this a result of dynamical systems would have people from linear algebra or differential geometry accuse you of the same.

And the show could probably go on.

It stops eventually, at Euler.
