@L-M-Sherlock do you plan to remove it now? If not, close this

Can you describe it step-by-step, please?

Also, regarding estimating the lowest value. For AUC and logloss, it can be done in the following way: 1) For each user, will will need alpha and beta to model...

Previously, I estimated alpha and beta an very crude way: 1) Take probabilities given by FSRS 2) Plot a calibration graph, like this: ![Image](https://github.com/user-attachments/assets/1906946c-52c7-4250-80b0-0afceb4e4604) Well, _plotting_ isn't necessary, but I'm...

You can plot one here: https://colab.research.google.com/github/open-spaced-repetition/fsrs4anki/blob/v5.3.1/fsrs4anki_optimizer.ipynb It's plotted after optimization I wonder if we can get alpha and beta from the bins themselves, without using FSRS predictions. It would probably...

When I say "Oracle", I mean "an algorithm that knows the true probability of recall for a given card at a given time". I DO NOT mean "an algorithm that...

> So you want something like {bin1: (0.90, 16), bin2: (0.95, 23), ...}? Yep.

> That is, do this calibration on the train set and see if it improves performance on the test set. If so, we may come up with an FSRS v4.1...

![Image](https://github.com/user-attachments/assets/f4e06c6e-f6f7-47f8-94fd-82fef0fcc57b) Alright, this looks promising. Kinda. Code: ``` import numpy as np from scipy.optimize import curve_fit from scipy.special import gamma def betafunc(x, a, b, scale): return scale * gamma(a+b) *...

Alright, I'll do it myself and then report the results.
