ForestPersons: A Large-Scale Dataset for Under-Canopy Missing Person Detection

ICLR 2026poster

Detecting missing persons in forest environments remains a challenge, as dense canopy cover often conceals individuals from detection in top-down or oblique aerial imagery typically captured by Unmanned Aerial Vehicles (UAVs). While UAVs are effective for covering large, inaccessible areas, their ae…

Stochastic Optimal Control for Continuous-Time fMRI Representation Learning

ICLR 2026poster

Learning robust representations from functional magnetic resonance imaging (fMRI) is fundamentally challenged by the temporal irregularity and noise inherent in data from heterogeneous sources. Existing self-supervised learning (SSL) methods often discard critical temporal information by discretizin…

Stochastic Optimal Control for Diffusion Bridges in Function Spaces

NeurIPS 2024poster

Recent advancements in diffusion models and diffusion bridges primarily focus on finite-dimensional spaces, yet many real-world problems necessitate operations in infinite-dimensional function spaces for more natural and interpretable formulations. In this paper, we present a theory of stochastic o…

On Divergence Measures for Bayesian Pseudocoresets

NeurIPS 2022accept

A Bayesian pseudocoreset is a small synthetic dataset for which the posterior over parameters approximates that of the original dataset. While promising, the scalability of Bayesian pseudocoresets is not yet validated in large-scale problems such as image classification with deep neural networks. On…
