- 3. The diagram below represents a feed forward neural network with a single hidden layer: 1 3 5 s 2 6 6 The link weight between nodes i and j is denoted by wij, for example w13 is the link weight between nodes 1 and 3. is the weight. The table below lists all weights in the network: W13 = -2 W35 = -1 W23 = 3 W45 = 1 W14 =4 W36 = 1 W24 = -1 W46 = 1 The following activation function is used on each of the nodes 3, 4, 5 and 6: = s(z) sz;z > 0 10;z 0 10;z
