NettetA weight of the representation V is a linear functional λ such that the corresponding weight space is nonzero. Nonzero elements of the weight space are called weight vectors. That is to say, a weight vector is a simultaneous eigenvector for the action of the elements of , with the corresponding eigenvalues given by λ. Nettet22. mar. 2024 · The general rule for setting the weights in a neural network is to set them to be close to zero without being too small. Good practice is to start your weights in the range of [-y, y] where y=1/sqrt (n) (n is the number of inputs to a given neuron).
