What is Overfitting in AI?
Overfitting in AI occurs when a model learns the training data too well, to the point where it performs poorly on unseen data. This is because the model has learned the noise and outliers in the training data, rather than the underlying patterns.
How does Overfitting occur in AI?
Overfitting occurs when a model is too complex relative to the amount and noise of the training data. This can happen when the model has too many parameters, or when it is trained for too long. The model ends up fitting the noise in the training data, leading to high accuracy on the training data but poor generalization to new data.
Overfitting can be mitigated by techniques such as regularization, early stopping, and data augmentation.
What are the implications of Overfitting in AI?
Overfitting can lead to poor performance on unseen data, which is often the ultimate goal in AI. It can also lead to overly complex models that are difficult to interpret and understand. Therefore, preventing overfitting is a key challenge in AI.
