Expand Your SCOPE: Semantic Cognition over Potential-Based Exploration for Embodied Visual Navigation

AAAI 2026technical

Embodied visual navigation remains a challenging task, as agents must explore unknown environments with limited knowledge. Existing zero-shot studies have shown that incorporating memory mechanisms to support goal-directed behavior can improve long-horizon planning performance. However, they overloo

From Prediction to Perfection: Introducing Refinement to Autoregressive Image Generation

ICLR 2026poster

Autoregressive (AR) models have emerged as a powerful framework for image generation, yet they remain bound by a fundamental limitation: once a prediction is made, it cannot be revised. Each step marches forward in a strict left-to-right sequence, causing small errors to accumulate and compromise th…

Quant Experts: Token-aware Adaptive Error Reconstruction with Mixture of Experts for Large Vision-Language Models Quantization

CVPR 2026

Post-Training Quantization (PTQ) has emerged as an effective technique for alleviating the substantial computational and memory overheads of Vision-Language Models (VLMs) by compressing both weights and activations without retraining the full model. Existing PTQ methods primarily rely on static iden

Boosting Lidar 3D Object Detection with Point Cloud Semantic Segmentation

IROS 2023poster

The integration of semantic information can effectively enhance the performance of 3D object detection based on lidar point cloud. Most of previous researches utilize camera-lidar fusion to improve detection accuracy for distant or small objects. However, this approach is typically unsuitable for re…
