WebApr 20, 2024 · Recently I read the WGAN-GP paper which points out that the clipping of weights essentially restricts the learning patterns of the discriminator, thus over-simplifying things. I looked at my loss values and saw that for a shallower model-- The losses hit a peak very fast (50th epoch) and then the losses oppose required trends.

WebWeight clipping ensures L-1 continuity by forcing the weights of the critic to a fixed interval. Any weights outside of this interval are then clipped, or set to the maximum or minimum amount allowed. The downside of this method is that it limits the critics ability to learn if you clip the weights too much.
