Why does the loss value change from positive to negative #59

Closed ICG0401 closed 2 years ago

ICG0401 commented 2 years ago

In the process of training, the value of loss is from positive to negative. However, in this paper, the loss function uses negative log likelihood. Why does the loss value appear to be negative?

It’s a generative model, frequent evaluation at some points can yield better results.
