Pretty sure the answer is no as a math problem where f is pure. If f returns the same answer each time, the square ending at N,N contains [1, N * N]. Then the rectangle ending at N,N+1 must contain (N * N, N * (N+1)] in the nonoverlapping s

Is your "winning" strategy so different from other social data / sentiment analysis approaches? There is some novelty with how you weigh the sentiments (based on how much of an insider or expert they are) but I am sure existi

The most damaging advice I ever got in my life was to talk to myself. I have always thought in mostly visual/symbolic terms. This made me really good with math early in my life, but it started failing when I began proof writing. Then I

I watched these lectures a few years ago and they were really good. Since this is meant to be a graduate level research course, I wonder if any cutting edge topics have been added since? Were there any major advances or new ideas in fundame

I wonder how they are going to handle security/abuse? Once the training is on end user devices, can't the user give fake results? For example back when recaptcha was introduced, trolls tried to transcribe everything as the n-word

I write a lot of scientific code with python and in those cases you really want your equations and matrix columns aligned for readability. These matrices appear so often adding fmt:off destroys the readability/elegance gain from the cl

Using ln as our utility, at time N we get: E[ln(X_1*...*X_N)] = sum E[ln(X)] So kelly happens to maximize this expected utility by construction since it was derived by maximizing expected log of one round of betting (E[ln(X)]). But i

I think the log is just the utility function. You could substitute it with any non-linear utility function and it would've gave you another answer that makes sense for that utility. The main takeaway is that a linear expected utility d

Tangentially related, this reminds me of the spy recordings[1] between incarcerated German nuclear physicists and their reactions to the atomic bomb dropping. At first they were incredulous and thought it must be a bluff. The bomb should be

One thing people don't realize is that a lot of web analytics software already do "session recording". So it can playback every wiggle of your mouse, every scroll, every keystroke, etc. You can see some creepy demos here: ht

If you're already using react/redux, there's one really nice pattern to make eventsourcing easy to implement. I learned it from the boardgame.io google project[1]. Basically redux is more or less already doing eventsourcing o

This visualization is really cool and innovative! It's useful for seeing the changes in the stream of values even if they are small relative to absolute magnitude (e.g., 1000001 -> 1000005 -> 1000003 etc). The tradition way to so
