In the example data file header should be pred_score instead of pred-score

1. Create a TSV with columns 'pred_score' and 'actual'. Save it to your_model_name.tsv. The columns should be separated by tabs. In each row:

   • actual should be 0 or 1 (True/False also work)
   • pred_score should be the score the model determined.
   • See the examples in example_data/
   • For example:

   actual  TYPO -> pred-score
   False   0.2
   True    0.8
   True    0.7
   False   0.3
