Can the code be used for 01 activation?

I wonder this code can be used for outputing only 0 or 1 for weights?How

I have the same question. I am confused why in the paper it is written that the sign function is used but the hardtanh is used in the implementation

[itayhubara]

the paper and code used the sign function for forward propagation and hardtanh for backward to preserve the gradient. This is the straight-through estimator.
