Optimising Hyperparameters Efficiently: How Hyperband and Successive Halving Speed Up Model Training
Hyperparameter tuning is essential for achieving optimal performance in machine learning and deep learning models. However, traditional methods like grid search and random search can be inefficient, especially for computationally expensive models. This is where Hyperband and Successive Halving come in. These advanced tuning techniques dynamically allocate resources (such as training epochs) to promising configurations while eliminating underperforming ones…
Machine learning models perform best when their hyperparameters are fine-tuned for the given dataset. Traditional grid search and random search methods are widely used, but they struggle with complex, high-dimensional search spaces.
