paper review: “High-Performance Large-Scale Image Recognition Without Normalization”

arxiv: key points introduce NF nets which combines multiple ideas to avoid using batch norm to get on-par performance but along with just using a bunch of non-BN techniques, this paper introduces adaptive gradient clipping(AGC) to make it actually train well to reach comparable results matching that of using Read more…

algorithm to find if closed path is rotating in right or left direction(finding right hande rule direction of closed loop)

A very simple mathmatical method exist to solve this problem. here is an interactive example: by calculating the signed area of a polygon, one can easily determine if a 2D directed path is rotating in the right or left direction.
