Neural networks can sometimes memorize their training data, including noise and irrelevant details, leading to overfitting. This occurs when a model performs exceptionally well on the data it was trained on but poorly on new, unseen data. Overfitting can be identified by a high training accuracy coupled with a significantly lower validation or test accuracy. Factors contributing to this issue include small datasets, overly complex models with too many parameters, excessive training epochs, and the absence of regularization techniques. AI
IMPACT Understanding overfitting is crucial for developing robust AI models that generalize well to real-world data.
