Question about "traj[:, :, 2]" #7

Closed pshijie closed 3 years ago

Hi，I'm very interested in your work. But I have question about this line of code:"(traj[:, :, 2]-1) % hours + 1". Is this variable in seconds or hours? Thanks!

It will help me greatly if you can be more precise about which line. If you mean line 104 in layer.py, then this is in hours. I explain in my paper that we divide time into 24*7 hours to consider weekly periodicity.
