VerifiedAI Operations

An organization deployed a fraud-detection model for credit card transactions. After training a complex neural network on a large volume of transactions, its training accuracy exceeded its validation accuracy. Which of the following is the MOST likely cause?

Explanation

Overfitting occurs when a model fits training-specific patterns too closely, producing stronger training performance than performance on unseen validation data. Complex neural networks are particularly susceptible when their learned complexity does not generalize.
