Central limit theorem and Cramér-type moderate deviations for Milstein scheme
Peng Chen, Hui Jiang, Jing Wang
In this paper, we investigate the Milstein numerical scheme with step size for a stochastic differential equation driven by multiplicative Brownian motion. Under some appropri…

InterSliceBoost: Identifying Tissue Layers in Three-dimensional Ultrasound Images for Chronic Lower Back Pain (cLBP) Assessment
Zixue Zeng, Matthew Cartier, Xiaoyan Zhao +12
Available studies on chronic lower back pain (cLBP) typically focus on one or a few specific tissues rather than conducting a comprehensive layer-by-layer analysis. Since three-dim…

Penalty-based Methods for Simple Bilevel Optimization under Hölderian Error Bounds
Pengyu Chen, Xu Shi, Rujun Jiang +1
This paper investigates simple bilevel optimization problems where we minimize an upper-level objective over the optimal solution set of a convex lower-level objective. Existing me…
