General info

Repository containing the code for the Project 1 of the Machine Learning course at EPFL.

The team (SchroedingerCats) is composed by:

The project has been developed and tested with Python 3.6, and the packages used to get the project up and running are listed in requirements.txt, and can be installed with:

pip3 install --user --requirement requirements.txt

For visualization purposes in the feature selection and engineering phase, we also used matplotlib, seaborn, sklearn, and pandas, but they are not needed to run the models and the final training.

The training and the prediction on the provided test sets can be done running:

python3 run.py

Moreover, the data are supposed to be in the data folder (with respect to the run.py script), and are supposed to have the names train.csv and test.csv. It is possible to download the data we used from this page.

The output of the prediction can be found in the final-test.csv file, located in the same folder as run.py.
