2. Neural Networks (8 points) Consider a two-input XOR function realized by a 2-layer Perceptron neural network as shown in Figure 3. The neuron model expressed as 0(x) = sgn(w.t), (1 0= 0 otherwise here w, stands for bias of a neuron. Try to compute and specify a set of weights for this two-input XOR neural network.
