kaggle-planet

Code for the Kaggle Understanding the Planet from Space Competition.

Overview

• This was a team effort with Grant Bruer.
• The final solution ranked 103rd of ~970 teams (top 11 percent).
• The final solution was a small ensemble of ResNets and DenseNets using test-time augmentation and some trickery to weight the ensemble votes for each image. This was not terribly different from the winning solution, though the winner did use a neat de-hazing trick which was described on the Kaggle discussions. In the end there was not much gain in using an ensemble. IIRC, you could get 91% accuracy with a simple 8-10 layer conv-net. This is referred to as "Goddard" in our repository.
• The repository is fairly messy; all of the models are convolutional networks implemented in Keras.
• Grant and I made a Google Doc outlining some of the things we learned
