Hyperopt – Neural Network Optimizing Hyperparameters: http://vooban.com/en/tips-articles-geek-stuff/hyperopt-tutorial-for-optimizing-neural-networks-hyperparameters/
Hyperopt is a way to search through an hyperparameter space. For example, it can use the Tree-structured Parzen Estimator (TPE) algorithm, which explore intelligently the search space while narrowing down to the estimated best parameters.
