While training an artificial neural network, the loss doesn't decrease as you expect. What could be some of the reasons? You have trained a Neural Network using Stochastic Gradient Descent (SGD) and L2 weight regularization with four different learning rates. The corresponding loss curves A,B,C, and D are shown below. Assign each of the learning rate value below to the proper curve (A/B/C/D). Explain why. Learn ing Rate s=[3e4,4e1,2e5,8e3]=[0.0003,0.4,0.00002,0.008]
