Asset Bundling for Wind Power Forecasting

no code implementations28 Sep 2023 Hanyu Zhang, Mathieu Tanneau, Chaofan Huang, V. Roshan Joseph, Shangkun Wang, Pascal Van Hentenryck

This approach effectively introduces an auxiliary learning task (predicting the bundle-level time series) to help the main learning tasks.

MAGI-X: Manifold-Constrained Gaussian Process Inference for Unknown System Dynamics

no code implementations27 May 2021 Chaofan Huang, Simin Ma, Shihao Yang

Ordinary differential equations (ODEs), commonly used to characterize the dynamic systems, are difficult to propose in closed-form for many complicated scientific applications, even with the help of domain expert.

An Infinite Hidden Markov Model With Similarity-Biased Transitions

no code implementations ICML 2017 Colin Reimer Dawson, Chaofan Huang, Clayton T. Morrison

We describe a generalization of the Hierarchical Dirichlet Process Hidden Markov Model (HDP-HMM) which is able to encode prior information that state transitions are more likely between "nearby" states.
