Solve an Aerial image recognition problem

The data set contains 9100 color images of size 128 x 128, images of 13 class, each having 700 images.
The classes are some kind of landscape or a natural environment, and more specifically :
beach, chaparral, cloud, desert, forest, island, lake, meadow, mountain, river, sea_ice, snowberg, wetland.

The goal of this challenge will be to classify each image and assign to it the correct label.

It is good to know a little in advance how to handle this challenge which is slightly more complicated than the one with the preprocessed data.
So to guide you a little bit, with our experience on this chalenge, a rather effective way to solve this classification task could be to use Deep Learning, more precisely, convolutional networks (CNNs).

Below some sample images :

If you want to use the competition's docker, you can use the commands below :

sudo docker run --name areal -it -v path/to/data:/home/aux -p 5000:8888 areal/codalab:pytorchv2

In the docker, run : jupyter-notebook --ip 0.0.0.0 --allow-root

After that, you have to copy-paste the line containing the link at the end and follow the instructions to entrer the address in your own browser outside the docker (don't forget to change 8888 to 5000 in the adress after the :), for example http://0.0.0.0:5000/?token=968e48d718ab5676d8c23c4a0d7bf3b088151d38fd3e1d86.

The notebook will be opened and you just have to navigate to find the README.ipynb (home -> aux -> starting_kit).

Once open, check that the kernel is a Python3 kernel. If it is, you're good to go. Else just change it to a Python3 kernel.

If you want to quit the docker, you can just type exit in the terminal, and type docker start areal to restart it.
