(i). Consider a 3-layer perceptron neural network consisting of 1 input neuron, 2hidden neurons with sigmoid activation functions, and 1 output neuron with linearactivation function. Assuming v1 and v2 represent the connection weights fromthe hidden neurons to the output neuron, v0 represents the bias for the outputneuron, w11 and w21 represent the connection weights from the input neuron tothe hidden neurons, and w10 and w20 represent the biases for the 2 hiddenneurons. Let x represent the input to the neural network and y represent the outputfrom the neural network.Suppose the vector of neural network weights is:w = [v0 v1 v2 w10 w11 w20 w21]T = [0 0.1 0.5 0 -1 1 0.2]T. Calculate the output y if input x = 0. Calculate y again for x = 1. (ii). For the same neural network as in (1), calculate the derivative of y with respect the neural network weight parameters v0, v1, v2 , w10 , w11 , w20, and w21 for x = 0. Calculate the derivatives again for x = 1.
Consider eight points on the Cartesian two-dimensional x-y plane. a g C For each pair of vertices u and v, the weight of edge uv is the Euclidean (Pythagorean) distance between those two points. For example, dist(a, h) : V4? + 1? = /17 and dist(a, b) = v2? + 0² = 2. Because many pairs of points have identical distances (e.g. dist(h, c) V5), the above diagram has more than one minimum-weight spanning tree. dist(h, b) = dist(h, f) Determine the total number of minimum-weight spanning trees that exist in the above diagram. Clearly justify your answer.
