Generalizable Disaster Damage Assessment via Change Detection with Vision Foundation Model

AAAI 2025technical

The increasing frequency and intensity of natural disasters call for rapid and accurate damage assessment. In response, disaster benchmark datasets from high-resolution satellite imagery have been constructed to develop methods for detecting damaged areas. However, these methods face significant cha…

Platform-Invariant Topic Modeling via Contrastive Learning to Mitigate Platform-Induced Bias

EMNLP 2024finding

Cross-platform topic dissemination is one of the research subjects that delved into media analysis; sometimes it fails to grasp the authentic topics due to platform-induced biases, which may be caused by aggregating documents from multiple platforms and running them on an existing topic model. This…

Towards Attack-tolerant Federated Learning via Critical Parameter Analysis

ICCV 2023poster

Federated learning is used to train a shared model in a decentralized way without clients sharing private data with each other. Federated learning systems are susceptible to poisoning attacks when malicious clients send false updates to the central server. Existing defense strategies are ineffective…

FedX: Unsupervised Federated Learning with Cross Knowledge Distillation

ECCV 2022poster

"This paper presents FedX, an unsupervised federated learning framework. Our model learns unbiased representation from decentralized and heterogeneous local data. It employs a two-sided knowledge distillation with contrastive learning as a core component, allowing the federated system to function wi…

Self-explaining deep models with logic rule reasoning

NeurIPS 2022accept

We present SELOR, a framework for integrating self-explaining capabilities into a given deep model to achieve both high prediction performance and human precision. By “human precision”, we refer to the degree to which humans agree with the reasons models provide for their predictions. Human precisio…

Improving Unsupervised Image Clustering With Robust Learning

CVPR 2021poster

Unsupervised image clustering methods often introduce alternative objectives to indirectly train the model and are subject to faulty predictions and overconfident results. To overcome these challenges, the current research proposes an innovative model RUC that is inspired by robust learning. RUC's n…

Mitigating Embedding and Class Assignment Mismatch in Unsupervised Image Classification

ECCV 2020poster

Unsupervised image classification is a challenging computer vision task. Deep learning-based algorithms have achieved superb results, where the latest approach adopts unified losses from embedding and class assignment processes. Since these processes inherently have different goals, jointly optimizi…
