What is Hyperopt primarily used for in machine learning?

Hyperopt is primarily designed for optimizing hyperparameters in machine learning models. Its primary functionality is centered around enabling efficient searching over hyperparameter spaces to find the optimal set of parameters for a given model. By employing techniques such as random search, grid search, and Bayesian optimization, Hyperopt is capable of distributing and parallelizing the hyperparameter optimization processes. This allows for more efficient use of computational resources—leading to faster and more effective model training.

The optimization capability of Hyperopt makes it particularly valuable in scenarios where tuning hyperparameters can significantly impact model performance. Utilizing its parallelization features enables users to run multiple hyperparameter configurations simultaneously, which increases the likelihood of finding the best parameters in a shorter timeframe.

The other options provided do not accurately represent the primary function of Hyperopt. While creating new algorithms, visualizing relationships, or automating data cleansing might be tasks relevant to machine learning in general, they are not the primary use case of Hyperopt.
