I think the idea is that some short peptides might survive the digestion and make it to the blood stream, but I'm doubtful there's any specific benefit to collagen.

I like einsum, it's concise and self-explanatory. Way better than multiple lines of nested for loops would be.

Also, the problem is to find a global min-cut, which requires all-pairs max flow.

Different models have different inductive biases. There is no way you could build GPT4 with decision trees.

Your edit is confusing me. Which variant fails and which variant passes?
Re:History of Uniform Random Number Generation (2017) [pdf]

Here's a variant which gives 64-bit output:
uint64_t x = 0, w = 1;
uint64_t msws64(void) {
x = x * x + (w *= 0xe9acc0f334e93bd5ULL);
return (x = (x >> 32) | (x << 32)) ^ w;
}

One important component is adding significant damping, corresponding to a small probability of jumping to a random page. This makes sure that the graph is well connected and the power iteration converges fast.

John Conway showed that if you generalise the coefficients of the Collatz conjecture then some instances are undecidable. So maybe there is no proof.

I would say the second law is more relevant; if you want to reduce entropy in one part of a system, you have to expend an equivalent or greater amount of free energy elsewhere.

Well, the derivations are different, and your comment seemed to imply that the maximum likelihood perspective was easier to understand.
Re:Kalman Filter Explained Simply

Both the Bayesian perspective and the optimization perspectice are legitimate ways of understanding the Kalman filter. I like the Bayesian perspective better.
