VerifiedWhen a model's training data contains benchmark test questions or highly similar content, the model may achieve high scores through memorization rather than genuine understanding.83% similarUnverifiedTraining data contamination is a common problem in machine learning, referring to a model being exposed during training to data that should not have been included, which may cause the model to learn to imitate the response patterns of other models.80% similarUnverifiedWhen a model can reproduce specific passages from its training data verbatim (the 'memorization' phenomenon), the 'transformative use' defense faces challenges.79% similarUnverifiedDuring LLM training, memorization occurs, where models may verbatim store fragments of training data and reproduce them during inference.79% similarUnverifiedIn large model training scenarios, personal data may be permanently encoded into model weights, making it impossible to delete and difficult to trace its specific influence on model outputs, rendering the GDPR's right to be forgotten technically difficult to implement.79% similar
