distilbert-base-uncased-finetuned-btc for PH66 Unwanted Event

• This is our initial attempt on using the transformers for BTC-PH66.

• This test file used in this model are in projects with Ids [1065, 950, 956, 2650]. The other 4 projects were not included as they resulted very low accuracy with ML models.

• The data was preprocessed to remove duplicates, and cases where the same cause-conseq has a different Unwanted Event

• Next Model: Improve the hyper-parameters of the model
