about Shannon entropy #6

Closed lsy-dot closed 2 years ago

lsy-dot commented 2 years ago

I'm so sorry to bother you, I recently read your masterpiece. I am very interested in the calculation method in the formula for calculating information entropy in the Prediction reliability part of your paper. I would like to ask how the probability represented by the symbol P of the formula is calculated. image

Thanks for your interest on our work!

Actually, the capitalized P denotes a probability function, which is an identity function in our final implementation and can be omitted. Meanwhile, the formula inside the P() is a softmax function which is calculated among various object-specific layers in a certain pixel-grid position.

Sorry for the confusion brought by the notation! We would clarify it in the next arxiv revision! Thanks!

Welcome to further questions and discussions!
