Validation helps in finding the balance between underfitting and overfitting, optimizing a model's performance.Review LaterTrueFalse

Answer

The statement is True.

Validation plays a crucial role in machine learning and statistical modeling as it helps in striking a balance between underfitting and overfitting the model.

1. Underfitting occurs when a model is too simple to capture the underlying patterns in the data, leading to poor performance on both training and validation datasets.

2. Overfitting, on the other hand, happens when a model is overly complex and captures noise along with patterns, resulting in exceptional performance on the training data but poor generalization to unseen data.

By using validation techniques such as cross-validation or holding out a validation dataset, we can monitor the model's performance as we adjust its complexity. This allows us to fine-tune hyperparameters and select the optimal model that generalizes well to new data, thus finding the right balance and optimizing performance.

In summary, validation is essential for model optimization, helping to ensure that the model is neither underfitting nor overfitting.
