Invited Talk 11: Tensor Methods for Efficient and Interpretable Spatiotemporal Learning

Multivariate spatiotemporal data is ubiquitous in science and engineering, from climate science to sports analytics, to neuroscience. Such data contain higher-order correlations and can be represented as a tensor. Tensor latent factor models provide a powerful tool for reducing dimensionality and discovering higher-order structures. However, existing tensor models are often slow or fail to yield interpretable latent factors. In this talk, I will demonstrate advances in tensor methods to generate interpretable latent factors for high-dimensional spatiotemporal data. We provide theoretical guarantees and demonstrate their applications to real-world climate, basketball, and neuroscience data.
