AD-LLM: Benchmarking Large Language Models for Anomaly Detection

ACL 2025finding

Anomaly detection (AD) is an important machine learning task with many real-world uses, including fraud detection, medical diagnosis, and industrial monitoring. Within natural language processing (NLP), AD helps detect issues like spam, misinformation, and unusual user activity. Although large langu…

DPU: Dynamic Prototype Updating for Multimodal Out-of-Distribution Detection

CVPR 2025highlight

Out-of-distribution (OOD) detection is crucial for ensuring the robustness of machine learning models by identifying samples that deviate from the training distribution. While traditional OOD detection has predominantly focused on single-modality inputs, such as images, recent advancements in multim…

NLP-ADBench: NLP Anomaly Detection Benchmark

EMNLP 2025

Anomaly detection (AD) is an important machine learning task with applications in fraud detection, content moderation, and user behavior analysis. However, AD is relatively understudied in a natural language processing (NLP) context, limiting its effectiveness in detecting harmful content, phishing

Treble Counterfactual VLMs: A Causal Approach to Hallucination

EMNLP 2025

Vision-Language Models (VLMs) excel at tasks such as image captioning and visual question answering but frequently produce hallucinated outputs that deviate from the actual visual input or prompt. While prior work links hallucination to biases in data or representation, their causal origins remain u

The Visual-Inertial- Dynamical Multirotor Dataset

ICRA 2022poster

Recently, the community has witnessed numerous datasets built for developing and testing state estimators. However, for some applications such as aerial transportation or search-and-rescue, the contact force or other disturbance must be perceived for robust planning and control, which is beyond the…

VID-Fusion: Robust Visual-Inertial-Dynamics Odometry for Accurate External Force Estimation

ICRA 2021poster

Recently, quadrotors are gaining significant attention in aerial transportation and delivery. In these scenarios, an accurate estimation of the external force is as essential as the six degree-of-freedom (DoF) pose since it is of vital importance for planning and control of the vehicle. To this end,…
