A question about the code "demo.py"

[packer-c]

Hello, thanks for sharing the excellent code.

Could you tell me the meaning of “295” at line 12？
time_coding = np.zeros((num_step, 295, 1), dtype="float32")

Looking forward to your reply.

Hi, thanks for your question. The 295 is the dimension of one-hot time embedding. As the traffic data is collected every 5 minutes, there are 288 time slots per day (calculated by 24 * 60 / 5). The last 7 positions represent the days of a week. 288 +7 = 295. Cheers.

Thank you for your reply. Understood. I also found more details in your paper.
Have a nice day!
