Spatially-Heterogeneous Causal Bayesian Networks for Seismic Multi-Hazard Estimation: A Variational Approach with Gaussian Processes and Normalizing Flows

no code implementations5 Apr 2025 Xuechun Li, Shan Gao, Runyu Gao, Susu Xu

These results highlight the critical importance of modeling spatial heterogeneity in causal mechanisms for accurate disaster assessment, with direct implications for improving emergency response resource allocation.

Disaster Response Gaussian Processes

Multi-resolution Score-Based Variational Graphical Diffusion for Causal Disaster System Modeling and Inference

1 code implementation5 Apr 2025 Xuechun Li, Shan Gao, Susu Xu

These systems manifest in both static scenarios with instantaneous causal chains and temporal scenarios with evolving dynamics, complicating modeling efforts.

From Perceptions to Decisions: Wildfire Evacuation Decision Prediction with Behavioral Theory-informed LLMs

no code implementations24 Feb 2025 Ruxiao Chen, Chenguang Wang, Yuran Sun, Xilei Zhao, Susu Xu

Evacuation decision prediction is critical for efficient and effective wildfire response by helping emergency management anticipate traffic congestion and bottlenecks, allocate resources, and minimize negative impacts.

Near-real-time Earthquake-induced Fatality Estimation using Crowdsourced Data and Large-Language Models

1 code implementation4 Dec 2023 Chenguang Wang, Davis Engler, Xuechun Li, James Hou, David J. Wald, Kishor Jaiswal, Susu Xu

Traditional systems for estimating human loss in disasters often depend on manually collected early casualty reports from global media, a process that's labor-intensive and slow with notable time delays.

Normalizing flow-based deep variational Bayesian network for seismic multi-hazards and impacts estimation from InSAR imagery

no code implementations20 Oct 2023 Xuechun Li, Paula M. Burgi, Wei Ma, Hae Young Noh, David J. Wald, Susu Xu

Onsite disasters like earthquakes can trigger cascading hazards and impacts, such as landslides and infrastructure damage, leading to catastrophic losses; thus, rapid and accurate estimates are crucial for timely and effective post-disaster responses.

Causality-informed Rapid Post-hurricane Building Damage Detection in Large Scale from InSAR Imagery

no code implementations2 Oct 2023 Chenguang Wang, Yepeng Liu, Xiaojian Zhang, Xuechun Li, Vladimir Paramygin, Arthriya Subgranon, Peter Sheng, Xilei Zhao, Susu Xu

We gathered and annotated building damage ground truth data in Lee County, Florida, and compared the introduced method's estimation results with the ground truth and benchmarked it against state-of-the-art models to assess the effectiveness of our proposed method.

HierMUD: Hierarchical Multi-task Unsupervised Domain Adaptation between Bridges for Drive-by Damage Diagnosis

1 code implementation23 Jul 2021 Jingxiao Liu, Susu Xu, Mario Bergés, Hae Young Noh

Monitoring bridge health using vibrations of drive-by vehicles has various benefits, such as no need for directly installing and maintaining sensors on the bridge.

Diagnostic Unsupervised Domain Adaptation

Knowledge Transfer between Buildings for Seismic Damage Diagnosis through Adversarial Learning

no code implementations21 Feb 2020 Susu Xu, Hae Young Noh

The supervised learning requires historical structural response data and corresponding damage states (i. e., labels) for each building to learn the building-specific damage diagnosis model.

MedAL: Deep Active Learning Sampling Method for Medical Image Analysis

no code implementations25 Sep 2018 Asim Smailagic, Hae Young Noh, Pedro Costa, Devesh Walawalkar, Kartik Khandelwal, Mostafa Mirshekari, Jonathon Fagert, Adrián Galdrán, Susu Xu

Active learning techniques can be used to minimize the number of required training labels while maximizing the model's performance. In this work, we propose a novel sampling method that queries the unlabeled examples that maximize the average distance to all training set examples in a learned feature space.
