WebThe bigger problem is computational complexity, as given W is d x n both forward and backward pass will have O (n^2d) complexity. So if this is a neural net layer, with 1000 units, such penalty requires 1,000,000,000 computations (as opposed to 1,000,000 in normal backprop). In general one rather should avoid pairwise penalties in the weight space. primland meadows of dan resort
