EPFL CS-433 Machine Learning - Project 2

crowdAI username: Tao Sun, submission ID: 23803

Team Members: Tao Sun, Xiao Zhou, Jimin Wang

Instructions

In order to reproduce the result we submitted to crowdAI, please follow the instructions as following:

  • Please make sure Python 3.6 and packages in requirements.txt are installed.
pip install -r requirements.txt

  • Please kindly download dataset from crowdAI, and then upzip and move training and test_set_images folders under the data\ folder.

  • If you want to get the results we submitted in the crowdAI, we have prepared models for you. Please download it from here, then unzip and move the three weights file into weights\ folder. Then run run.py, you will get the submission.csv under the submission\ folder.

python run.py
  • If you want to retrain our models, please run train_predict.py, you will then directly get the submission.csv under the submission\ folder.
python train_predict.py

Modules

data.py
