I am using logsoftmax and NLLLoss. for my classification problem (50 classes)
My training accuracy decreased after 88 epoch.
In 88 epoch: Accuracy is 51 %
Maximum in 84 epoch : 71 %
Suddenly in 89 epoch accuracy is 1.34 %
stuck at 1.34 after that (>89 epoch)
learning_rate = 1e-4
optimizer = optim.SGD(model.parameters(), lr=0.0015, momentum=0.9)
Please suggest, why It is like thar
