The dataset is global in coverage, spans multiple years at high sampling frequency, and is designed such that resulting emulators are compatible with downstream coupling into operational climate simulators.

Two-step hyperparameter optimization method: Accelerating hyperparameter search by using a fraction of a training dataset

1 code implementation • 8 Feb 2023 • Sungduk Yu, Mike Pritchard, Po-Lun Ma, Balwinder Singh, Sam Silva

Hyperparameter optimization (HPO) is an important step in machine learning (ML) model development, but common practices are archaic -- primarily relying on manual or grid searches.
