Careful Queries, Credible Results: Teaching RAG Models Advanced Web Search Tools with Reinforcement Learning

AAAI 2026technical

Retrieval-Augmented Generation (RAG) enhances large language models (LLMs) by integrating up-to-date external knowledge, yet real-world web environments present unique challenges. These limitations manifest as two key challenges: pervasive misinformation in the web environment, which introduces unre

FlexCAD: Unified and Versatile Controllable CAD Generation with Fine-tuned Large Language Models

ICLR 2025poster

Recently, there is a growing interest in creating computer-aided design (CAD) models based on user intent, known as controllable CAD generation. Existing work offers limited controllability and needs separate models for different types of control, reducing efficiency and practicality. To achieve con…

GeoCAD: Local Geometry-Controllable CAD Generation with Large Language Models

NeurIPS 2025poster

Local geometry-controllable computer-aided design (CAD) generation aims to modify local parts of CAD models automatically, enhancing design efficiency. It also ensures that the shapes of newly generated local parts follow user-specific geometric instructions (e.g., an isosceles right triangle or a…

STraj: Self-training for Bridging the Cross-Geography Gap in Trajectory Prediction

AAAI 2025technical

Accurate trajectory prediction has prominent significance in autonomous driving scenarios. Most existing methods predict the trajectory of an agent by learning its interaction with other agents and the map within the scenario. However, the heterogeneous distribution of these elements across differe…

G2LTraj: A Global-to-Local Generation Approach for Trajectory Prediction

IJCAI 2024poster

Predicting future trajectories of traffic agents accurately holds substantial importance in various applications such as autonomous driving. Previous methods commonly infer all future steps of an agent either recursively or simultaneously. However, the recursive strategy suffers from the accumulated…

Pseudo Label Refinery for Unsupervised Domain Adaptation on Cross-dataset 3D Object Detection

CVPR 2024poster

Recent self-training techniques have shown notable improvements in unsupervised domain adaptation for 3D object detection (3D UDA). These techniques typically select pseudo labels i.e. 3D boxes to supervise models for the target domain. However this selection process inevitably introduces unreliable…
