A question about the testing process. about gru4rec_tensorflow HOT 2 OPEN

Thanks for discussing this!
You are right this is the implement in the original Hidash's code. While I agree that using tanh as final activation function maybe problematic, especially together with cross entropy loss (negative number in log()).
I only run this code with softmax activation and cross entropy loss. Would you please share a bit more on how you use tanh in your experiments? With what kind of loss function? How the performance is going?

The original paper said that it is better to use tanh.
