type ii error is statistics, not mathematics. there is no equivalent concept in CS because type ii error relates specifically to statistical inference and hypothesis testing.
that said, if you are just pointing to a box in a confusion matrix and saying "TYPE II ERROR," you are probably trying too hard.
- eachro 9y agoEh, but if you've taken a machine learning course, you should have seen the notion of false positive/false negative when you cover any kind of classification technique.
- aoki 9y agobut they're not actually equivalent, in spite of tables like this [0]. type ii error is a false negative result in the context of a test, where you have to understand which hypothesis is which and exactly what you are accepting or rejecting (hypotheses are not always as simple as hotdog/not-hotdog); if your listener doesn't know what statistical tests mean or wasn't following the setup, they have to stop you and ask.
