MoSs: Mixture of Scales for Efficient High-Resolution Autoregressive Image Generation

AAAI 2026technical

Since next-scale prediction was introduced as a new paradigm for autoregressive image generation, it has attracted extensive research interest. By progressively increasing resolution in a draft-to-refinement process, next-scale prediction demonstrates great potential in both generation quality and e

STEP: Warm-Started Visuomotor Policies with Spatiotemporal Consistency Prediction

ICML 2026poster

Diffusion policies have recently been as a powerful paradigm for visuomotor control in robotic manipulation due to their ability to model the distribution of action sequences and capture multimodality. However, iterative denoising leads to substantial inference latency, limiting control frequency in…

Hierachical Balance Packing: Towards Efficient Supervised Fine-tuning for Long-Context LLM

NeurIPS 2025poster

Training Long-Context Large Language Models (LLMs) is challenging, as hybrid training with long-context and short-context data often leads to workload imbalances. Existing works mainly use data packing to alleviate this issue, but fail to consider imbalanced attention computation and wasted communic…

OmniBal: Towards Fast Instruction-Tuning for Vision-Language Models via Omniverse Computation Balance

ICML 2025poster

Vision-language instruction-tuning models have recently achieved significant performance improvements. In this work, we discover that large-scale 3D parallel training on those models leads to an imbalanced computation load across different devices. The vision and language parts are inherently hetero…

Enhancing Vectorized Map Perception with Historical Rasterized Maps

ECCV 2024poster

"In autonomous driving, there is growing interest in end-to-end online vectorized map perception in bird’s-eye-view (BEV) space, with an expectation that it could replace traditional high-cost offline high-definition (HD) maps. However, the accuracy and robustness of these methods can be easily comp…
