Clip threshold of gradients
WebDec 19, 2016 · The clip_by_value function has a local gradient of zero outside of the range min_delta to max_delta, so whenever the delta is above min/max_delta, the gradient becomes exactly zero during... WebAug 15, 2016 · I followed Alex Graves' paper for gradient clipping. The idea is to clip the individual dimension of the gradient separately. As far as I know, the Caffe main code scales the whole gradient based on L2-norm. In this case, the gradient direction is preserved. I think this (scaling) is more widely used these days.

WebIf you attempted to clip without unscaling, the gradients’ norm/maximum magnitude would also be scaled, so your requested threshold (which was meant to be the threshold for unscaled gradients) would be invalid. scaler.unscale_ (optimizer) unscales gradients held by optimizer ’s assigned parameters. WebClipping the gradient by value involves defining a minimum and a maximum threshold. If the gradient goes above the maximum value it is capped to the defined maximum. ...
