[theano-users] How to clip tensor value only in forward-pass, not in backward-pass?

[Sihyeon Seong]

Hi, I found out T.clip(x, min, max) makes gradient zero when x is not in
[min, max].

It would be useful if there is a function only clips value in the forward
pass, and calculate df/dx(x=max) at the backward-pass.

Is the function I explained exist in Theano? Or, can somebody teach me how
to implement it? Thanks.
