Hi @colinyong !
Under sample setting
bullet point? I recommend setting the Under sample setting
to random undersample
and the under sample ratio
to 1.0
to see if that helps. Thank you very much. In fact, I annotated at least ten thousand frames for each behavior from different videos and also set the Under sample settings to modify the classifiers, but the result was still the same. Next, I plan to set Over sample settings to see if it can improve the performance of classifier.
Got it! Another way to understand more what's going on: If you look at the classification videos, are there anything obvious in common you can see with the frames the classifier is missing.
Hello, I use Simba to train different classifiers and output classification reports. For some classifiers, the precision is very high, but the recall value is very low. 1)I'm wondering how to handle this situation, is it ok if I only focus on precision? 2)By setting hyperparameters, the recall value can be improved, but at the same time the precision value will decrease. To what extent do I need to adjust the hyperparameters? Is it when f1 is the biggest?
