Evolving Deep Networks Using HPC
Workshop: Machine Learning in HPC Environments
Authors:
Abstract: While a large number of deep learning networks have been studied and published that produce outstanding results on natural image datasets, these datasets only make up a fraction of those to which deep learning can be applied. These datasets include text data, audio data, and arrays of sensors that have very different characteristics than natural images. As these "best" networks for natural images have been largely discovered through experimentation and cannot be proven optimal on some theoretical basis, there is no reason to believe that they are the optimal network for these drastically different datasets. Thus, hyperparameter search is often a very important process when applying deep learning to a new problem. In this work, we present an evolutionary approach to searching the possible space of network hyperparameters and construction that can scale to 18,000 nodes. This approach is applied to datasets of varying types and characteristics where we demonstrate the ability to rapidly find best hyperparameters in order to reduce enable practitioners to quickly iterate between idea and result.
