Dataset

The Food-101 dataset, originally made available at https://data.vision.ee.ethz.ch/cvl/datasets_extra/food-101/ is a data set of 101 food categories, with 101'000 images.

Training

Fast.ai was used to train this classifier with a ResNet50 vision learner, without much customization.

The final fine tuning of the training loop resulted in the following losses.
