How to use this model to measure sequence similarity

[cxydaizihao520]

Hello,please I have some questions：
1、you said that each key contains:( _ , 50, 2, 17) pose.what is the 50 mean?I understand it is the length of each piece of data, which is related to the sampling rate. According to your other paper, it is about 5 seconds.
2、How can I use this model to measure sequence similarity? Is it a direct input of two sequences X and Y. And is the value of L2 norm directly returned and then mapped to a score？
Thank you for advance!
