What are you reporting:

• Evaluation dataset(s) found in a pre-training corpus. (e.g. COPA found in ThePile)
• Evaluation dataset(s) found in a pre-trained model. (e.g. FLAN T5 has been trained on ANLI)

Evaluation dataset(s): Name(s) of the evaluation dataset(s). If available in the HuggingFace Hub please write the path (e.g. uonlp/CulturaX), otherwise provide a link to a paper, GitHub or dataset-card.

• MedNLI
• RadNLI

Contaminated model(s):

• This PR reports negative results for GPT-3.5 and GPT-4.

Contaminated corpora: None

Contaminated split(s): 0% over train/dev/test (MedNLI) and dev/test (RadNLI).

Briefly describe your method to detect data contamination

• Data-based approach
• Model-based approach

Description of your method, 3-4 sentences. Evidence of data contamination (Read below):

• (Method is same as PR 3)
• The only difference between this implementation and the original paper's (Golchin and Surdeanu 2024) is that here multiple runs (3 runs) were performed on each available split; this was to make sure that results hold across different (identically-sized) random data partitions. In addition the models were accessed through Azure OpenAI (opt out of human review + HIPAA-compliant), following MIMIC's DUA. For reference, a sanitized version of the results that keeps the data index, label, outputs, and contamination evaluation results without original input sentences can be found here.
• While there are potential positives identified by the ROUGE-based contamination detection method, the best performing (GPT-4 ICL) detector did not consider these instances to be true contaminations, therefore this PR reports negative results (0% contamination for all splits on both datasets based on the examined method).

Is there a paper that reports the data contamination or describes the method used to detect data contamination?
