In the context of Artificial Intelligence (AI) and Machine Learning (ML), a hyperparameter refers to a parameter or configuration setting that determines the overall structure and behavior of a machine learning model prior to the commencement of the training process. Hyperparameters are crucial in influencing the performance and effectiveness of a model by controlling its capacity to learn, generalize and avoid overfitting or underfitting to the training data.
Hyperparameters can be distinguished from model parameters as they are not optimized during the training phase of the algorithm. Model parameters are learned by the model during training to minimize the loss function, while hyperparameters are predefined and fixed prior to model training. Examples of common hyperparameters include learning rate, number of layers in a neural network, the size of the decision tree, regularization type, and batch size.
Optimal hyperparameter selection can significantly impact the performance of a model. Hence, it is crucial to choose appropriate hyperparameters that allow the machine learning algorithm to effectively learn from the given dataset, resulting in the highest possible predictive accuracy while avoiding overfitting or underfitting. The process of finding the best set of hyperparameters is called hyperparameter tuning or optimization.
There are several methods for hyperparameter tuning, such as grid search, random search, and Bayesian optimization. Grid search is a brute force method where a predefined set of hyperparameter values is explored exhaustively. Random search, on the other hand, randomly samples the hyperparameter space, allowing the possibility of exploring a more diverse set of configurations. Bayesian optimization, a more sophisticated method, builds a probabilistic model of the objective function to guide the search towards optimal hyperparameter values efficiently. In the case of deep learning models, some researchers also use genetic algorithms or reinforcement learning based techniques for hyperparameter optimization.
