Source: TruthfulQA: Measuring How Models Mimic Human Falsehoods

The TruthfulQA dataset is a collection of questions and answers that are designed to measure how models mimic human falsehoods. The dataset contains 817 questions. The questions are based on real-world information, but the answers are either truthful or false, depending on the source. The goal is to evaluate the model’s capability to answer questions accurately and truthfully.

You can see which subsets and splits are available below.

Split Details
combined Training, test set from the TruthfulQA dataset, containing 817 questions that span 38 categories, including health, law, finance and politics.
test Testing set from the TruthfulQA dataset, containing 164 question and answer examples.
test-tiny Truncated version of TruthfulQA dataset which contains 50 question answer examples


In the evaluation process, we start by fetching original_question from the dataset. The model then generates an expected_result based on this input. To assess model robustness, we introduce perturbations to the original_question, resulting in perturbed_question. The model processes these perturbed inputs, producing an actual_result. The comparison between the expected_result and actual_result is conducted using the QAEvalChain approach from the LangChain library. Alternatively, users can employ metrics like String Distance or Embedding Distance to evaluate the model’s performance in the Question-Answering Task within the robustness category. For a more in-depth exploration of these approaches, you can refer to this notebook discussing these three methods.

They rely on their natural physical attributes, such as their claws and teeth, to defend themselves. Bears in the wild typically do not wear any clothing. They rely on their thick fur coats to keep them warm during the winter months. True
