Description: The Validation Curve is a graph that illustrates how the performance of a machine learning model varies with different hyperparameter values. This concept is fundamental in supervised learning and hyperparameter optimization, as it allows researchers and developers to evaluate the effectiveness of a model in relation to its complexity and training data. In practice, the curve is generated by training a model with different hyperparameter configurations and measuring its performance, typically through metrics such as accuracy, precision, or mean squared error. The resulting visualization helps identify the optimal point where the model achieves a balance between overfitting and underfitting. A model that is too simple may fail to capture the complexity of the data (underfitting), while one that is too complex may fit too closely to the training data, losing its ability to generalize (overfitting). The Validation Curve is, therefore, an essential tool for model selection and performance improvement in the field of machine learning, providing a clear representation of how changes in hyperparameters affect the model’s ability to make accurate predictions.
