Title: Democratizing Deep Learning Development with DeepHyper
Abstract: In recent years, deep neural networks (DNNs) have achieved considerable success in learning complex nonlinear relationships between features and targets from large datasets. Nevertheless, designing high-performing DNN architecture for a given data set is an expert-driven, time-consuming, trial-and-error manual task. A major bottleneck in the construction of DNNs is the vast search space of architectures that need to be explored in the face of new data sets. Moreover, DNNs typically require user-specified values for hyperparameters, which strongly influence performance factors such as training time and prediction accuracy. In this talk, we will introduce participants to DeepHyper, a scalable automated machine learning package for developing deep neural networks. DeepHyper provides an infrastructure that targets experimental research in neural architecture search (NAS) and hyperparameter search (HPS) methods, scalability, and portability across diverse supercomputers through the use of the different workflow manager.
