AI doesn’t replicate. Having worked in the field, I can usually see why a paper’s result is nonsense, but the public can’t, and many researchers can’t.https://twitter.com/stephaniemlee/status/964612382650646529 …
Oh, I should have said also, I meant bitwise parallel xor, which does not require a deep circuit; not parity. Bitwise xor takes backprop exponential time to learn.

Parallel xor is still not a great test of anything; but the right defense of backprop should have been “xor is not a good test; here is a good test, and backprop passes.”

To be totally careful I should also say that my memory is that it’s exponential, but it was a long time ago, and I may be wrong.
