SaPaVe: Towards Active Perception and Manipulation in Vision-Language Action Models for Robotics

CVPR 2026

Active perception and manipulation are crucial for robots to interact with complex scenes. Existing methods struggle to unify semantic-driven perception actively with robust, viewpoint-invariant execution accordingly. To this end, we propose SaPaVe, an end-to-end framework that jointly learns these

TIGeR: Tool-Integrated Geometric Reasoning in Vision-Language Models for Robotics

ICRA 2026poster

Vision-Language Models (VLMs) have shown remarkable capabilities in spatial reasoning, yet they remain fundamentally limited to qualitative assessments and lack the computational precision required for real-world robotics. Current approaches fail to leverage metric information from depth sensors and…

CO2-Net: A Physics-Informed Spatio-Temporal Model for Global Surface CO2 Reconstruction

ICCV 2025poster

Reconstructing atmospheric surface \text CO _2 is crucial for understanding climate dynamics and informing global mitigation strategies. Traditional inversion models achieve precise global \text CO _2 reconstruction but rely heavily on uncertain prior estimates of fluxes and emissions. Inspired by r…

NeRF-Based Transparent Object Grasping Enhanced by Shape Priors

ICRA 2025

Transparent object grasping remains a persistent challenge in robotics, largely due to the difficulty of acquiring precise 3D information. Conventional optical 3D sensors struggle to capture transparent objects, and machine learning methods are often hindered by their reliance on high-quality datase

RoboRefer: Towards Spatial Referring with Reasoning in Vision-Language Models for Robotics

NeurIPS 2025poster

Spatial referring is a fundamental capability of embodied robots to interact with the 3D physical world. However, even with the powerful pretrained VLMs, recent approaches are still not qualified to accurately understand the complex 3D scenes and dynamically reason about the instruction-indicated lo…

Shoes-ACOSI: A Dataset for Aspect-Based Sentiment Analysis with Implicit Opinion Extraction

EMNLP 2024finding

We explore *implicit opinion extraction* as a new component of aspect-based sentiment analysis (ABSA) systems. Prior work in ABSA has investigated opinion extraction as an important subtask, however, these works only label concise, *explicitly*-stated opinion spans. In this work, we present **Shoes-…

Learning Joint Structural and Temporal Contextualized Knowledge Embeddings for Temporal Knowledge Graph Completion

ACL 2023findings

Temporal knowledge graph completion that predicts missing links for incomplete temporal knowledge graphs (TKG) is gaining increasing attention. Most existing works have achieved good results by incorporating time information into static knowledge graph embedding methods. However, they ignore the con…

Modeling Precursors for Temporal Knowledge Graph Reasoning via Auto-encoder Structure

IJCAI 2022poster

Temporal knowledge graph (TKG) reasoning that infers missing facts in the future is an essential and challenging task. When predicting a future event, there must be a narrative evolutionary process composed of closely related historical facts to support the event's occurrence, namely fact precursors…

TraEDITS: Diversity and Irregularity-Aware Traffic Trajectory Editing

RA-L 2022

We present TraEDITS, a novel traffic trajectory editing framework for autonomous vehicle testing, which can generate new traffic behaviors by controlling each vehicle interactively to increase the diversity or irregularity of traffic testing data. Given a traffic flow with its original trajectories,

WiDetect: A Robust and Low-Complexity Wireless Motion Detector

ICASSP 2018accepted

Motion detection as a key component in modern security systems has received an increasing attention recently, but most existing solutions require special installation, calibration, and only have a limited coverage. In this paper, we propose WiDetect, a highly accurate, calibration-free, and low-comp…
