Description: The Subspace Method is an approach that optimizes hyperparameters in a reduced-dimensional space. This method is based on the idea that, in many optimization problems, the search space can be extremely large and complex, making it difficult to identify the best hyperparameter configuration. By reducing the dimensionality of the search space, the Subspace Method allows for more efficient and effective exploration of hyperparameter combinations. This approach relies on mathematical and statistical techniques that identify relevant subspaces where optimal solutions are more likely to be found. Dimensionality reduction not only speeds up the optimization process but can also improve model generalization by avoiding overfitting. In summary, the Subspace Method is a powerful tool in hyperparameter optimization, facilitating the search for configurations that maximize the performance of machine learning models and other complex algorithms.
