Aug 19, 2020 at 21:26 comment added Tahlor Suppose every node has the same input weights. Then every node in a given layer has the same activation (output value). Then every node in a given layer gets the same weight updates. So the weights are still the same after each update. Adding an additional node in a given layer is then equivalent to having just 1 node in that layer and multiplying the weights by a constant.
