I don't think this is a failure of Automatic Differentiation. It's a failure of assuming that the derivative of an approximation is equal to an approximation of the derivative. That's obviously nonsense, as the example f(x) =

That makes more sense. The title is flat out wrong IMO.

Why? Is this important as a sanity check in the absence of any independent verifications?

The phase space formulation of QM still only uses REAL-valued probabilities, but outside the interval [0,1]. I'm not sure I agree with the rest of your comment either.

The phase space formulation of QM uses less complex numbers than the Schrodinger one: it models states using quasi-probability distributions, where the "probabilities" behave in all the usual ways except they can go negative. Inte

The real numbers can be "represented" and "computed with" without needing approximations. The result is that there are no rounding errors. But it's not popular, and not necessarily worth the tradeoffs. On the other

It follows from matrices of the form [[a, (-n)b], [b, a]] being closed under multiplication, and taking determinants. In more advanced language: For R a commutative ring (like say, the integers) the following function f is a ring homomorphi

Maybe you should use a reasoning model. Got this from O3, which took 1m31s to think about the answer: https://chatgpt.com/s/t_687b9221fb748191af4e30f597f18443 Bottom line: Your 5800X3D + 64 GB RAM + RTX 3090 will run K

Hallucinations might get solved by faster, cheaper and more accurate, vision and commonsense-physics models. Hypothesis: Hallucinations are a problem only because physical reality isn't text. Once people switch to models that predict p

This is perfect news for consumers and terrible news for investors. Which are you?

Vision and everyday-physics models are the answer: hallucinations will stop when the models stop thinking in words and start thinking in physical reality.

by ogogmad 1y ago
The next step is clearly improved vision and everyday-physics models. These can also solve hallucinations.

I think the article's point is that the notion of "groups" per se is too coarse for DH, because it abstracts away the data structure you use to represent the elements of the group. However, the notion of Algebraic Groups does

There's a mapping there, however it's not natural.

Why don't some phrases arrive at the same meaning? They don't commute.

I think you're describing inelastic demand for hires. Which I mentioned as a hole in the argument. On that note, I'm not sure why my post has more down than upvotes.

Your final remark sounds condescending. Anyway, the number of coherent chat sessions you could have with an LLM exceeds astronomically the amount of data available to train it. How is that even possible?

Maybe I'm nitpicking, but the Triceratops wouldn't be appropriate here. The point here is that the Megalosaurus was a real-life sea monster. The metaphor in the text is that it would appear that a flood had come and gone - which i
