Hi @colinyong!
(1) The classifier needs annotation examples what freezing looks like, what what freezing doesn't look like, from a variable set of videos. Ideally the annotations should contain examples of edge-cases and: as in "a naive observer might have difficulties with this one". It's difficult to say how many annotations you need, as it depends on how good your tracking is and the complexity of your behavior. There are some example annotations count in the SImBA priprent table 2: https://www.biorxiv.org/content/10.1101/2020.04.19.049452v2.full.pdf.
If you only annotate parts of the videos (and skip annotating some frames) - there are a few annotations methods in SimBA that differ in the way they handle those un-annotated frames - e.g., should the un-annotated frames be assumed not containing the behavior, or should we skip using them in the classifier. You can read more about it here: https://github.com/sgoldenlab/simba/blob/master/docs/label_behavior.md
hello, I'm a newbie and use simba for the first time.
1) I'm curious when labeling the behavior, do I need to label all the frames of interest or just need to label part of them?For example, I want to classify the freezing behaviror. For a full video, maybe there are one hundred of this behavior, do i need to label all of them? if labeling 10 of this behavior, does it can work?
2) I only foucs on freezing behavior, so in addition to freezing behavior, do i need to creat another classifier named non-freezing behavior and then label it?
