Multi-Region Markovian Gaussian Process: An Efficient Method to Discover Directional Communications Across Multiple Brain Regions

no code implementations5 Feb 2024 Weihan Li, Chengrui Li, Yule Wang, Anqi Wu

Consequently, the model achieves a linear inference cost over time points and provides an interpretable low-dimensional representation, revealing communication directions across brain regions and separating oscillatory communications into different frequency bands.

A Differentiable Partially Observable Generalized Linear Model with Forward-Backward Message Passing

no code implementations2 Feb 2024 Chengrui Li, Weihan Li, Yule Wang, Anqi Wu

For (1), we propose a new differentiable POGLM, which enables the pathwise gradient estimator, better than the score function gradient estimator used in existing works.

Variational Inference

Forward $χ^2$ Divergence Based Variational Importance Sampling

no code implementations4 Nov 2023 Chengrui Li, Yule Wang, Weihan Li, Anqi Wu

Maximizing the log-likelihood is a crucial aspect of learning latent variable models, and variational inference (VI) stands as the commonly adopted method.

Forecasting battery capacity and power degradation with multi-task learning

no code implementations29 Nov 2021 Weihan Li, Haotian Zhang, Bruis van Vlijmen, Philipp Dechent, Dirk Uwe Sauer

In this paper, we propose a data-driven prognostics framework to predict both capacity and power fade simultaneously with multi-task learning.
