Validation Dataset Unused in Tutorial? #21

Closed ghost closed 8 years ago

ghost commented 8 years ago

Hello, @alexgkendall! Thank you for sharing the code. I have looked at the SegNet tutorial and its corresponding model prototxt. However, I have noticed that the validation dataset (val.txt) is not used. Could you explain why? Also, is then the training accuracy based on the training dataset? Thank you for your time! :-)

Yes, the training accuracy is from the training set. Useful to look at how well the model fits the data (especially when you consider bayesian segnet's uncertainty). Absolutely, you can validate your model on the val.txt dataset, in the tutorial I don't bother with this for simplicity.

Aha! That perfectly makes sense. Thank you for your explanation!
