Publication number: 20210264287Abstract: Tuned hyperparameter values are determined for training a machine learning model. When a selected hyperparameter configuration does not satisfy a linear constraint, if a projection of the selected hyperparameter configuration is included in a first cache that stores previously computed projections is determined. When the projection is included in the first cache, the projection is extracted from the first cache using the selected hyperparameter configuration, and the selected hyperparameter configuration is replaced with the extracted projection in the plurality of hyperparameter configurations. When the projection is not included in the first cache, a projection computation for the selected hyperparameter configuration is assigned to a session. A computed projection is received from the session for the selected hyperparameter configuration.Type: ApplicationFiled: October 27, 2020Publication date: August 26, 2021Inventors: Steven Joseph Gardner, Joshua David Griffin, Yan Xu, Patrick Nathan Koch, Brett Alan Wujek, Oleg Borisovich Golovidov
