![]() Rather than the information you actually wanted to know. It will help you remember irrelevant information or random noise, It will optimize your memory of just about anything,īut if you don’t phrase your question correctly, Thus, overfitting improves the model’s accuracy rate on the training dataīut reduces it when it’s applied to new data,īecause the SRS is so good at helping you learn things efficiently, That would be useful in predicting new information. Of course, random noise does not represent any meaningful relationship It starts to treat random noise present in the training data Overfitting, in statistical modeling and machine learning, To put it another way, SRS questions are prone to overfitting. Which you would never encounter in real life. In other cases, you could end up memorizing a grammatical error on your card, So I would never have thought to use the optionĪnd this information was pretty much worthless to me. That cp had such an option in the first place, ![]() I easily and correctly answered, “ cp -i,”īut as I gave that answer, I realized that I had completely forgotten The SRS is rather like the proverbial genie:ĭescribe what you want to get in the wrong way,Īnd the genie will interpret your wish in the most ridiculous way possibleĪnd you’ll learn something that’s of no practical use.įor instance, I recently found a card with an interval of several yearsĪsking what option to the cp (copy) Unix command That isn’t useful or doesn’t test the things you want to know,īut it won’t help you at all you’ll just be wasting your time doing reviews.īecause seemingly small variations in how you ask a questionĬan push it into not testing the thing you intended it to. ![]() However, it is a strongly garbage-in, garbage-out tool: The importance of asking the right questionsĪn SRS does a fantastic job of helping you remember It’s one of those resources you learn more from every time you read it. It would be hard to overstate the importance and influence of this documentĪnd if you have not read it, you should do so now,Īs a matter of fact, you should read it twice,Īnd keep returning to and rereading it as you learn more about spaced repetition – SuperMemo’s Twenty Rules of Formulating Knowledge. Throughout the next couple of posts on creating cards for spaced-repetition systems, Is a complex discipline of its own that’s both an art and a science,Īnd how well you do at designing your cardsĮasy study sessions resulting in effective learningĪnd frustrating ones resulting in mediocre learning.Ĭard design is thus the most fundamental skill of spaced-repetition use,Īnd it’s worth spending some time learning how to do it well.
