Integrate into Anki

[dae]

Edit: new PR is here: ankitects/anki#2633

[asukaminato0721]

Will investigate once burn-rs/burn#690 is merged

merged.

That PR didn't quite do what I'd hoped - it still displays progress on the console, and does not seem to expose individual item counts (only the epoch changes). It looks like it may be possible to achieve the desired result by building our own learner though - will investigate further.

I have a very rough draft implemented, that will print the weights but not integrate them in the collection. Burn-rs currently includes a number of dependencies that are quite old and have security issues, and those will need to be addressed before I can proceed further.

Awesome work!

What's the next step? Would you like to integrate the scheduler part into Anki, or still let users use custom scheduling?

[dae]

First priority is getting the licenses and old dependencies sorted out. After that, I'll need to test this prototype and make sure it can be compiled/run across the different platforms. Assuming that's all ok, once you feel the weight generation of this crate is not lacking compared to the Python optimizer, it should be ok to include in Anki. To start with, users would continue to use custom scheduling, but the next logical step would be to integrate the reviewing part of FSRS into the Rust code as well.

I've got #48 hooked up. Still waiting on a few more PRs to burn-rs to be approved.

Advice for the calculation of optimal retention:

Constraint of range for the input values could avoid some weird result. Here is my code in the gradio app:

            with gr.Column():
                weights = Textbox(label="Weights", lines=1,
                                  value="0.4, 0.6, 2.4, 5.8, 4.93, 0.94, 0.86, 0.01, 1.49, 0.14, 0.94, 2.18, 0.05, 0.34, 1.26, 0.29, 2.61")
                learning_time = Slider(label="Learning Time perday (minutes)",
                                       minimum=5, maximum=1440, step=5, value=30)
                learn_span = Slider(label="Learning Period (days)", minimum=30,
                                    maximum=3650, step=10, value=365)
                deck_size = Slider(label="Deck Size (cards)", minimum=100,
                                   maximum=100000, step=100, value=10000)
            with gr.Column():
                max_ivl = Slider(label="Maximum Interval (days)", minimum=30,
                                 maximum=36500, step=10, value=36500)
                recall_cost = Slider(label="Review Cost (seconds)", minimum=1,
                                     maximum=600, step=1, value=10)
                forget_cost = Slider(label="Relearn Cost (seconds)",
                                     minimum=1, maximum=600, step=1, value=30)
                learn_cost = Slider(label="Learn Cost (seconds)", minimum=1,
                                    maximum=600, step=1, value=10)

That of course makes sense, but I'm focusing on the basic functionality at the moment - polish can come later :-)
