On the Convergence of Black-Box Variational Inference

2023 · arXiv (Cornell University)

We provide the first convergence guarantee for full black-box variational inference (BBVI), also known as Monte Carlo variational inference. While preliminary investigations worked on simplified versions of BBVI (e.g., bounded domain, bounded support, only optimizing …

Discovering Latent Causal Graphs from Spatiotemporal Data

2024 · arXiv (Cornell University)

Many important phenomena in scientific fields like climate, neuroscience, and epidemiology are naturally represented as spatiotemporal gridded data with complex interactions. Inferring causal relationships from these data is a challenging problem compounded by the high …
