If you'd like to make use of our dataset, the train_data and test_data_balanced csvs are well suited to use when running classifiers or regressors on the data.
Note: test_data.csv and test_data_balanced.csv are different because we needed to rebalance our test data to have an equal number of 'Excellent' and 'Very good' quality coffee.
