Abstract: Generally discussed herein are devices, systems, and methods for identifying optimal hyperparameter values within a pre-defined budget. A method can include, while training a model for a number of iterations using values of a hyperparameter vector, recording objective function values of the objective function and cost function values of a cost function, fitting a function model to the objective function values and a cost model to the cost function values resulting in a fitted function model and a fitted cost model, selecting a second hyperparameter vector, determining an optimal number of iterations to perform and after which to stop training using the second hyperparameter vector, re-training the model of the type of model for the optimal number of iterations using the second hyperparameter vector, and providing hyperparameter values, of the hyperparameter vector or the second hyperparameter vector, that maximize an objective defined by the objective function.

Abstract: Examples of the present disclosure describe systems and methods for probabilistic neural network architecture generation. In an example, an underlying distribution over neural network architectures based on various parameters is sampled using probabilistic modeling. Training data is evaluated in order to iteratively update the underlying distribution, thereby generating a probability distribution over the neural network architectures. The distribution is iteratively trained until the parameters associated with the neural network architecture converge. Once it is determined that the parameters have converged, the resulting probability distribution may be used to generate a resulting neural network architecture. As a result, intermediate architectures need not be fully trained, which dramatically reduces memory usage and/or processing time.
