Hi, thanks for the code. I am also confused why 2 channels are used for the TCL & TR? it will be great if you can briefly explain or refer me to where it is explained in paper.

@spoorgholi74 , without special resons. if you're using sigmoid activate function, one channel is required. Two-channel feature map is set to be compatible with softmax activate function and cross-entropy loss, use one channel if you prefer it :)
