Hi，thank you for sharing. It's a great job.After read your paper,I have some question. (a) what's the appropriate value of the threshold 'σ' defined Mi = exp(−σ · (||X i −X i+1 ||2) (Eqn. 5)? (b) the value of Di and ˆDi+1 in Eqn. 2 is the output of the network or the normalized of the network?(Di是网络直接的输出结果 还是 网络输出的然后归一化的结果)
