"This is the most important thing. By far the worst failure mode is to put too much in a flashcard."

He's wrong on this one. The problem with making extremely atomic flashcards is that many times it's impossible to prevent slight amounts of overlap between the cards. What this means is that answering card A might contain information that allows you to answer some subsequent card B.

As a result you end up effectively getting a hint for some dependent cards, as opposed to if you had to recall all that information from scratch.

Thanks for this resource.

It is timely for me, because I am finding memory is probably the limiting factor for me learning about machine learning. So many concepts and names of things to remember. Once you get past 1-2 lectures the short term memory becomes overloaded and it gets muddled.

I also worry that chatgpt is going to make my memory worse, because I no longer have to remember stuff, and I can just remember what they asked chat gpt. I think there is value to even remembering APIs and syntax from heart.

So this post is counter "just get the computer to do it" which is a good thing.

I can imagine that just like people didn't need gyms when they had to hunt, gather and survive, but now we do, we will need mental gyms to make up for what technology has made too easy.

Earlier quoted context omitted.

At Math Academy ( https://mathacademy.com ), we implement spaced repetition in combination with a knowledge graph consisting of several thousand math topics and tens of thousands of connections (and growing). We're working on a post that explains how this all works technically. We have a Linear Algebra course ( https://mathacademy.com/courses/linear-algebra ) that some of you might find interesting given how often th…

Is there a way to try it out (at least for a week) without paying the $49?

There's a 30-day free trial, so if you cancel during that period you get a complete refund.

A few things that I've come to learn using space repetition systems...

* You are effectively memorizing. Memorizing something takes a long time compared to other learning techniques like learning concepts and looking up details as needed. I find it works best if I'm selective about what to memorize since memorizing everything limits the breadth of what I can learn in general.

* Mnemonic devices, even ones that seem silly, are incredibly valuable for things that are hard to remember. It may take time to find or think up a mnemonic, but it's worth the up-front effort.

* If you naturally have unavoidable life interruptions every week/month that require you to skip learning days, you may be happier with more forgiving algorithms. Algorithms like the supermemo algorithm used by Anki try to push you right up to the edge of you ability to remember it. I still maintain old flashcards in those systems, but I'm much happier since I started tracking my learning in a custom spreadsheet where I control the algorithm.

I use ChatGPT to create Mnemonic devices out of the lines from my favorite movies for my Accounting flashcards :)

Has anyone used spaced repetition in their research/job for a problem they are trying to solve? I sometimes feel like there are many aspects I need to hold in my brain at once and keep having the need to revisit them. If I could chunk these aspects through spaced repetition it seems things could be easier.

I know Michael Nielson got insights by using spaces repetition for some math properties, but my usecase is a bit different.

Other software which have nailed spaced repetition (and a much better UI than Anki): - https://www.duolingo.com/ (language learninig) - https://www.chessable.com/ (chess) - https://readwise.io/ (book highlights) - https://examarly.com/ (test prep) - https://app.bestudious.io/login (certifications - CFA) - https://magoosh.com/ (vocabulary)

For language, I can vouch for both Clozemaster and Lingvist as very polished tools that put the spaced repetition front-and-centre unlike Duolingo.
