NextStep-1: Toward Autoregressive Image Generation with Continuous Tokens at Scale

ICLR 2026oral

Prevailing autoregressive (AR) models for text-to-image generation either rely on heavy, computationally-intensive diffusion models to process continuous image tokens, or employ vector quantization (VQ) to obtain discrete tokens with quantization loss. In this paper, we push the autoregressive parad…

DreamBench++: A Human-Aligned Benchmark for Personalized Image Generation

ICLR 2025poster

Personalized image generation holds great promise in assisting humans in everyday work and life due to its impressive function in creatively generating personalized content. However, current evaluations either are automated but misalign with humans or require human evaluations that are time-consumin…

Perception-R1: Pioneering Perception Policy with Reinforcement Learning

NeurIPS 2025poster

Inspired by the success of DeepSeek-R1, we explore the potential of rule-based reinforcement learning (RL) in MLLM post-training for perception policy learning. While promising, our initial experiments reveal that incorporating a thinking process through RL does not consistently lead to performance…

ChatSpot: Bootstrapping Multimodal LLMs via Precise Referring Instruction Tuning

IJCAI 2024poster

Human-AI interactivity is a critical aspect that reflects the usability of Multimodal Large Language Models (MLLMs). However, existing end-to-end MLLMs only allow users to interact with them through language instructions, leading to the limitation of the interactive accuracy and efficiency. In this…

Exploring Recurrent Long-Term Temporal Fusion for Multi-View 3D Perception

RA-L 2024

Long-term temporal fusion is a crucial but often overlooked technique in camera-based Bird's-Eye-View (BEV) 3D perception. Existing methods are mostly in a parallel manner. While parallel fusion can benefit from long-term information, it suffers from increasing computational and memory overheads as

GroupLane: End-to-End 3D Lane Detection With Channel-Wise Grouping

RA-L 2024

Efficiency is quite important for 3D lane detection while previous detectors are either computationally expensive or difficult for optimization. To bridge this gap, we propose a fully convolutional detector named GroupLane, which is simple, fast, and still maintains high detection precision. Specifi

Vary: Scaling up the Vision Vocabulary for Large Vision-Language Models

ECCV 2024poster

"Most Large Vision-Language Models (LVLMs) enjoy the same vision vocabulary, i.e., CLIP, for common vision tasks. However, for some special task that needs dense and fine-grained perception, the CLIP-style vocabulary may encounter low efficiency in tokenizing corresponding vision knowledge and even…
