2. Given five samples and three features (X1, X2, x3) and the corresponding labels y: Sample X1 X2 1 1 1 2 1 0 3 1 1 4 0 1 5 1 0 Nm X3 1 0 0 1 1 1 0 0 1 1 We want to train a neural network on this data. The input layer has three nodes, the output layer has one artificial neuron, and there are no hidden layers. The activation function is the sigmoid function. Write a python code which trains the network. P.S. Do not use classes
