.3 Learning in Artificial Neural Networks
• As shown in Table 6.1, each calculation uses one of the X1 and X2 pairs and the corresponding value for OR operation, along with the initial values, W1 and W2 , of the neuron’s weights. Initially, the weights are assigned random values, and the learning rate, alpha, is set low. Delta is used to derive the final weights, which then become the initial weights in the next iteration (i.e., row).
