The problem about self.rel_rec and self.rel_send

[1zgh]

            rel_rec = self.rel_rec.cuda(gpu_id)
	rel_send = self.rel_send.cuda(gpu_id)

	self.logits = self.encoder(x, rel_rec, rel_send) 

The dim of rel_rec and rel_send is 【600，25】,but I can not understand what they mean about human skeleton. AIM network is a little hard to understand. I would appreciate it if you could elaborate on your ideas. Thanks!!

I have read the code too, it's difficult to understanding the encoder-decoder as well.
