Your goal is to predict the ‘Score’ column of the submission file. Your submission will be evaluated using the RMSE cost function. Please review what RMSE means before starting on the project.
Review scores are between 1 and 5 (1, 2, 3, 4, 5). If you predict a decimal result, round it up or down to the closest integer within review scores to finalize your prediction for that review. You will have to submit the results for the reviews indicated in the sampleSubmission.csv file.
