1. Justify demotion in principle: Look at the mnemosyne-proj data so far (or even just your own data), and show (I suspect) that the pass rate after a failure is unnecessarily high. This would justify demotion rather than failure. 2. Just as the "initial ef" is autoadjusted based on the individual's accumulated results, the global "demotion factor" could be set by looking at the pass rate after demotion. For example, start with some safe guess, such as /4, then adjust over time so that the cumulative pass rate after demotion is, let's say, about the same as the individual's overall pass rate, indicating that these cards are being put back about where they belong. 3. Furthermore, optionally, once the above is done, some data will be available that I don't think can be deduced from the accumulated mnemosyne-proj data: For a given demotion factor look at pass-rate- after-demotion versus length-of-interval-before-demotion. I suspect that the longer the interval before the miss, the bigger the demotion required. (Here is my reasoning for this guess if you want to see it: Upon missing an old card, you receive a little reminder of something you "know very well". You say to yourself: Oh yeah, I knew that! But the *next time* you see this card, it might be the case (I experience this) that the answer comes not by recovering the old (supposedly well known) memory, but by remembering that little reminder, which is *newer*.) The simplest way to handle this would be with a discrete function: one divisor for short interval, one (or more) for longer ones.
Conclusion: I've never trusted that "6" in the SM2 algorithm. *In the context of the above*, what it is in effect doing is imposing this policy, of more severe demotion for longer intervals, in the bluntest possible way. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "mnemosyne-proj-users" group.
