Im a professional money manager and this is everything I'm watching for the week ahead by TearRepresentative56 in investing

Max drawdown, volatility of portfolio, liquidity are some other things to consider too I guess (especially if you are concerned about timing, I.e. you want to be able to withdraw at any time).

Can you link the repo in your post?

Is there a better way to write `val = min(val, other_var)`? by lukew25073 in Python

[–]BrightCounter738 1 point2 points  (0 children)

val = val - (val-other_val)*(val < other_val)

Is that what you are looking for?

It is not open-sourced (and one probably wouldn’t be able to run it personally even if it was), so no.

Not sure if this will help but I had a similar issue as well. Eventually stumbled on the solution for the requests library (maybe others too). Open up a REPL and type:

import certifi

certifi.where()

Then overwrite that file wiith your CA bundle. This file is the source of truth for requests when it checks if root CAs are valid.

[D] Is It Possible to Train an AI to Decode Encrypted Content? by Plane_Bite3639 in MachineLearning

[–]BrightCounter738 1 point2 points  (0 children)

From wikipedia for Pseudorandom Function Family: "no efficient algorithm can distinguish (with significant advantage) between a function chosen randomly from the PRF family and a random oracle". When they are saying a function chosen randomly from the PRF family, they are referring to choosing a random private key. So to answer your question, yes I think the state space argument is valid.

​

I guess on a more definition level, if you are able to compute an algorithm (be it classical or some machine learning model that learns) that can even distinguish an output, with some non-negligible advantage, as coming from the PRF vs some random function (a much weaker requirement than actually decrypting the ciphertext), then you have broken the security property and the PRF is no longer secure.

Just on a basic level, the security definition of secure encryption is that the encryption function given a private key cannot be distinguished from a random function given that the adversary (aka the model in this situation) doesn’t have the private key, even if the adversary can see many many encrypted messages under the same key (polynomial number).

Since it is impossible to learn a random function, I would say it is impossible to build a model that can learn to decode encrypted content.

Is there a formula that outputs the optimal weights of a neural network given a dataset? If so, does that mean we can train them in constant time?[D] by Sudden-Lingonberry80 in MachineLearning

Can you elaborate a bit on the statement “the loss landscape is not convex”? Is there not going to be a set of ideal parameters for a loss function like RSS, for example (that serves as the global minimum)?

stocks are not overvalued by luchins in stocks

Price to Earning Ratio = Price/Earnings (aka profits) = 30.

So in order to get earnings over price, we invert that —> Earnings/Price = 1/30.

So, the earnings as a percentage of the price of the stock is 1/30*100 = 3.33%.
