Learning Transition Kernels of Jump-Diffusion Processes with Conditional Diffusion Models

We study the problem of learning transition kernels for time-homogeneous jump-diffusion processes using conditional diffusion models, with the goal of generating new sample paths from training data consisting of N independent trajectories observed on a high-frequency discrete time grid. On the theoretical side, we esta …

ABO-Med: Accelerated Bilevel Optimization for Few-Shot Medical Image Classification

Ruoxuan Shi, Sheng Yang, Zhengxing Su وآخرون · 2026

In recent years, bilevel optimization has been widely used in a variety of machine learning tasks. However, prior bilevel optimization algorithms generally require the computation of second-order information, which limits their practical scalability. Only recently has a first-order paradigm for bilevel optimization bee …
