Predictive Entropy and Uncertainty #17

Thank you for the great code~I have a theoretical question to ask. What is the significance of averaging the prediction results for T forward propagation?

This is a classification problem in which uncertainty can be calculated by predictive entropy without T forward propagation. Since predictive entropy itself can represent uncertainty, I wanted to confirm the significance of averaging over T forward propagations.
