How Much Data are Enough? Investigating Dataset Requirements for Patch-Based Brain MRI Segmentation Tasks

no code implementations4 Apr 2024 Dongang Wang, Peilin Liu, Hengrui Wang, Heidi Beadnall, Kain Kyle, Linda Ly, Mariano Cabezas, Geng Zhan, Ryan Sullivan, Weidong Cai, Wanli Ouyang, Fernando Calamante, Michael Barnett, Chenyu Wang

This paper focuses on an early stage phase of deep learning research, prior to model development, and proposes a strategic framework for estimating the amount of annotated data required to train patch-based segmentation networks.

A Deep Learning Analysis of Climate Change, Innovation, and Uncertainty

no code implementations19 Oct 2023 Michael Barnett, William Brock, Lars Peter Hansen, Ruimeng Hu, Joseph Huang

We study the implications of model uncertainty in a climate-economics framework with three types of capital: "dirty" capital that produces carbon emissions when used for production, "clean" capital that generates no emissions but is initially less productive than dirty capital, and knowledge capital that increases with R\&D investment and leads to technological innovation in green sector productivity.

Precise Few-shot Fat-free Thigh Muscle Segmentation in T1-weighted MRI

no code implementations27 Apr 2023 Sheng Chen, Zihao Tang, Dongnan Liu, Ché Fornusek, Michael Barnett, Chenyu Wang, Mariano Cabezas, Weidong Cai

However, due to the insufficient amount of precise annotations, thigh muscle masks generated by deep learning approaches tend to misclassify intra-muscular fat (IMF) as muscle impacting the analysis of muscle volumetrics.

Learning from pseudo-labels: deep networks improve consistency in longitudinal brain volume estimation

no code implementations8 Feb 2023 Geng Zhan, Dongang Wang, Mariano Cabezas, Lei Bai, Kain Kyle, Wanli Ouyang, Michael Barnett, Chenyu Wang

An accurate and robust quantitative measurement of brain volume change is paramount for translational research and clinical applications.

TW-BAG: Tensor-wise Brain-aware Gate Network for Inpainting Disrupted Diffusion Tensor Imaging

no code implementations31 Oct 2022 Zihao Tang, Xinyi Wang, Lihaowen Zhu, Mariano Cabezas, Dongnan Liu, Michael Barnett, Weidong Cai, Chengyu Wang

Diffusion Weighted Imaging (DWI) is an advanced imaging technique commonly used in neuroscience and neurological clinical research through a Diffusion Tensor Imaging (DTI) model.

Decompose to Adapt: Cross-domain Object Detection via Feature Disentanglement

1 code implementation6 Jan 2022 Dongnan Liu, Chaoyi Zhang, Yang song, Heng Huang, Chenyu Wang, Michael Barnett, Weidong Cai

Recent advances in unsupervised domain adaptation (UDA) techniques have witnessed great success in cross-domain computer vision tasks, enhancing the generalization ability of data-driven deep learning architectures by bridging the domain distribution gaps.

Methods for Extracting Information from Messages from Primary Care Providers to Specialists

no code implementations WS 2020 Xiyu Ding, Michael Barnett, Ateev Mehrotra, Timothy Miller

Electronic consult (eConsult) systems allow specialists more flexibility to respond to referrals more efficiently, thereby increasing access in under-resourced healthcare settings like safety net systems.

Multiple Sclerosis Lesion Inpainting Using Non-Local Partial Convolutions

no code implementations24 Dec 2018 Hao Xiong, Chaoyue Wang, DaCheng Tao, Michael Barnett, Chenyu Wang

However, existing methods inpaint lesions based on texture information derived from local surrounding tissue, often leading to inconsistent inpainting and the generation of artifacts such as intensity discrepancy and blurriness.
