Hyperparameter optimization in machine learning intends to find the hyperparameters of a given machine learning algorithm that deliver the best performance as measured on a validation set. Hyperparameters, in contrast to model parameters, are set by the machine learning engineer before training. The n...
Machine learning is all about fitting models to data. This process typically involves using an iterative algorithm that minimizes the model error. The parameters that control a machine learning algorithm’s behavior are called hyperparameters. Depending on the values you select for your...

Face based on Syne Tune. We saw that by optimizing hyperparameters such as learning rate, batch size, and the warm-up ratio, we can improve upon the carefully chosen default configuration. We can also extend this by automatically selecting the pre-trained model via hyp...
Tips Bayesian optimization is not reproducible if one of these conditions exists: You specify an acquisition function whose name includesper-second, such as'expected-improvement-per-second'. Theper-secondmodifier indicates that optimization depends on the run time of the objective function. For more ...
Automating the search is an important step towards automating machine learning, freeing researchers and practitioners alike from the burden of finding a good set of hyperparameters by trial and error. In this survey, we present a unified treatment of hyperparameter optimization, providing the reader ...
