Neural Ordinary Differential Equation based Sequential Image Registration for Dynamic Characterization

no code implementations2 Apr 2024 Yifan Wu, Mengjin Dong, Rohit Jena, Chen Qin, James C. Gee

Leveraging Neural Ordinary Differential Equations (ODE) for registration, this extension work discusses how this framework can aid in the characterization of sequential biological processes.

FireANTs: Adaptive Riemannian Optimization for Multi-Scale Diffeomorphic Registration

1 code implementation1 Apr 2024 Rohit Jena, Pratik Chaudhari, James C. Gee

We demonstrate compelling improvements on image registration across a spectrum of modalities and anatomies by measuring structural and landmark overlap of the registered image volumes.

Generative Adversarial Bayesian Optimization for Surrogate Objectives

1 code implementation9 Feb 2024 Michael S. Yao, Yimeng Zeng, Hamsa Bastani, Jacob Gardner, James C. Gee, Osbert Bastani

To address this limitation, we propose generative adversarial Bayesian optimization (GABO) using adaptive source critic regularization, a task-agnostic framework for Bayesian optimization that employs a Lipschitz-bounded source critic model to constrain the optimization trajectory to regions where the surrogate function is reliable.

The Role of Chain-of-Thought in Complex Vision-Language Reasoning Task

no code implementations15 Nov 2023 Yifan Wu, Pengchuan Zhang, Wenhan Xiong, Barlas Oguz, James C. Gee, Yixin Nie

The study explores the effectiveness of the Chain-of-Thought approach, known for its proficiency in language tasks by breaking them down into sub-tasks and intermediate steps, in improving vision-language tasks that demand sophisticated perception and reasoning.
