Torch Tutorial for PlantVillage Challenge.
I have trained the alexnet model with the above augmentation technique for 120 epochs. On a machine with Nvidia Titan X, each epoch took about 3/4 minutes. It took about 7 hrs to train the network. On my Macbook Air, each epoch takes this much time.
I get a F-Score of 0.99 with this network :).
I also have trained resnet-34 (ResNet is the winner of the latest ImageNet challenge) and got almost the same F-Score.
You can train these yourself using accompanying repo. Feel free to mail me if you have found any bugs.
