Good afternoon Professor. Here are some questions about examples. 1. In the project description you provide a sample document sample2.tsv. Is this document only for testing with best_predictor? 2. During the actual detection, whether a tsv file is provided, processed by cantril_data_cleaning, and then given to best_predictor for testing. Or will different tsv be provided for these two scripts for detection. 3. Is it possible to check whether best_predictor is correct by directly running ./best_predictor sample2.tsv? That is, if my own output is different from the example you provided, it means there is something wrong with my script. Thank you very much.
