What does "fulfill himself as a flight" mean? Is the lesson that since professors are "less free" than everyone else, they criticize everyone else out of bitterness? Or is it that since they're so specialized and ab

It would be nice if in Python you could define new operators instead of overloading existing ones. It would make matrix multiplication look nicer. I'm thinking it could look like this: import numpy as np def M1 %*% M2 with sam

No that's Bayes' theorem, not Bayesian inference. You haven't made any Bayesian assumptions.

Not only do we have previous knowledge, we know basically everything about what's going on. You only use Bayesian inference if there is something you don't know which can't be computed from the things you do know. Then, after

Bayesian statistics is a way of updating your beliefs about the value of some unknown number (or value) after doing an experiment. You have to be uncertain about some variable, and then you work backwards to figure out its value. In the cas

Does this comment deserve a downvote? I think he's asking a genuine question.

Do you think there's any hope of finding a practical algorithm for USTON that runs in logarithmic space? Reingold's algorithm needs O(n^64^32) time(!!!)

A qubit is a linear combination of |0> and |1>, and a qutrit is a linear combination of |0>, |1> and |2>. I remember Scott Aaronson once suggested building QCs with qudits (or qu-n-its with n>2).

I think oracle separations are currently only useful as barrier results, showing that certain proof techniques can't solve the full problem.

From what I can tell: that while this memory-management strategy can stop a program from seg-faulting or from executing remote code, the style of programming is the same as with `malloc` and `free`. You still have to `alloc_texture()` and `

Off topic but I couldn't get hibernate to work on Ubuntu Linux. I purchased a laptop with Linux pre-installed; but apparently, if a manufacturer claims to support Linux on a laptop , that does not include hibernate support. Now that

No. The relevant theorem is called Darboux's Theorem. It states that if f(x) has a derivative f'(x) everywhere, then f'(x) satisfies the intermediate value property, meaning: If f'(A) < 0 and f'(B) > 0 then th

`For` expressions are not boolean blind compared to map/flatmap/filter. (Boolean blindness: https://existentialtype.wordpress.com/2011/03/15/boolean-bli... ) That might be an advantage.

`map` is not going to make it faster. `map` is a loop. Only vectorized code is faster.

Here's a diagram [1] of a one-hidden-layer NN. It has 2 activation functions. Their NN is of the same type. [1] - https://raw.githubusercontent.com/qingkaikong/blog/master/40...

One thing I don't like about Python libraries, from the top of my head: That there is a distinction between functions and methods, e.g. between nansum(a) and a.sum() where a is a numpy array. The distinction is illogical and just has t

You're wrong. See section 5.1. I've drawn a graph of it that shows it to be a classical NN with a single output node.

> The "depth-three" model in this paper is a bit strange in that their second layer has only one output, so the third linear layer doesn't have any effect. I would have called this "depth two"; but it is internal

It's probably referring to policy iteration[1]. It works by iterating two steps: - Keep the policy $\pi$ fixed, and determine the $Q$ values for that policy - Keep the $Q$ value estimates fixed, and create a policy $\pi'$ such tha

How is this different from Pypy, other than the fact that ones uses RPython and the other uses Rust?

I had another idea for making constant time programs. The idea is that you create a virtual machine without loops or branch instructions, in which each instruction is tested so that the amount of time it takes is independent of the instruct

Slightly off-topic, but maybe we need a fully standardized and unambiguous CSV dialect with its own file extension. Or maybe just use SQLite tables or Parquet? Some things I dislike about CSV: * No distinction between categorical data and s
