A little while ago some of the MSc students were complaining about some homework that required them to classify very bad photos of fish (from a Kaggle competition). Not sure how well they did (hopefully well). I did initially think a group of us could have a go at the problem. However Ayman suggested trying a competition about sea lions instead as they are cuter. Information can be found at https://www.kaggle.com/c/noaa-fisheries-steller-sea-lion-population-count. Essentially we would develop a method to count the number of sea lions in an aerial photo. Might not get very far in three days but it's worth a go. The only issue seems to be that the dataset is a little on the large size, so anyone with a 1-2TB HDD would be useful. Might need to download the dataset in advance due to poor wi fi at the hostel.
