It is the follow-up to the previous post Some problems in implementing a state-of-the-art SRS scheduler on Anki . Thanks to the support of dae and RumovZ, I implement a simplified version of the fsrs algorithm in open-spaced-repetition/fsrs4anki (github.com) . The customData works well! But there ar…

Anki and FSRS You can view the new features in: [image] New features of FSRS4Anki from v3.0.0 to v3.6.0 Scheduling Continuing the discussion from Big update in FSRS4Anki v3.0.0 : This week, I updated FSRS4Anki from v3.0.0 to v3.6.0. Here is a summary of the ne…

Doesn’t @dae technically have access to a larger dataset of anyone who uses AnkiWeb? Maybe ask if he can share that with you for analysis.

[image] fcsing: After reading the paper, it seems that their dataset is specifically language learning so scientifically speaking there is no basis to comment on other topic. This is my one doubt about this new algorithm. The work @L.M.Sherlock is doing is fantastic and I’m super appreciative…

I am developing a new feature to analyze the review logs in a more explainable way. The short/long intervals would be more acceptable if you see the analysis of your own reviews.

To be specific I’ve always taken the Anki algorithm/SM-2 to be inefficient for my use case for SRS, i.e. it results in too many reviews and gives me an excessive workload. So I was surprised to see FSRS giving even short intervals in many cases, resulting in more reviews. The SM-18 algorithm by co…

[image] kuroahna: However, I wouldn’t overlook FSRS just yet. For some analysis, I’ve got my friend who’s learning Japanese with about ~11k cards in his deck who has 88.7% young monthly retention rate, 87.8% mature monthly retention rate, and 88.4% young+mature monthly retention rate: True re…

[image] kuroahna: Overall, it’ll be nice if we can get more accurate comparisons and analysis between Anki SM-2 and FSRS to convince users why FSRS could be better than SM-2, but I don’t think we have the data yet since it’s in its early stages and needs more users to test. I wonder if it’s poss…

Right, mature cards are cards with >=21 day interval. That’s honestly quite an arbitrary number. And young cards are cards with <21 day interval. The analysis generated by FSRS optimizer is more accurate. Are you referring to the new analysis table that you recently added to v3.2.0? In your oth…

[image] kuroahna: I feel like there’s that optimal spot between the interval spacing and retention rate where you do the least amount of reviews. It need the optimizer give an optimal request retention. In my paper, I implement it in C++ because it is too complicated and Python is too ineffic…

Oh that’s interesting. With all the math libraries available, including ones written in CPython I had assumed Python would be more than up to number crunching tasks like this. Is the Google Colab optimizer for fsrs4anki still behind the capability of your C++ one?

[image] biodecus: Is the Google Colab optimizer for fsrs4anki still behind the capability of your C++ one? The Google Colab optimizer doesn’t include the module. You can see the module at: maimemo/SSP-MMC/blob/main/algo/main.cpp #include <cmath> #include <cstdio> #include <ct…
