abstract

Pretrained multilingual large language models have typically used heuristic temperature-based sampling to balance between different languages. However previous work has not systematically evaluated the efficacy of different pretraining language distributions across model scales. In this paper, we propose a new sampling method, UniMax, that delivers more uniform coverage of head languages while mitigating overfitting on tail languages by explicitly capping the number of repeats over each language's corpus. We perform an extensive series of ablations testing a range of sampling strategies on a suite of multilingual benchmarks, while varying model scale. We find that UniMax outperforms standard temperature-based sampling, and the benefits persist as scale increases. As part of our contribution, we release: (i) an improved and refreshed mC4 multilingual corpus consisting of 29 trillion characters across 107 languages, and (ii) a suite of pretrained umT5 model checkpoints trained with UniMax sampling.

ASTRA: Let Arbitrary Subjects Transform in Video Editing

cs.CV · 2025-10-01 · unverdicted · novelty 7.0

ASTRA is a plug-and-play training-free method for precise multi-subject video editing that uses prompt-guided multimodal alignment and prior-based mask retargeting to avoid attention dilution and boundary issues.

OpenCoF: Learning to Reason Through Video Generation

cs.CV · 2026-07-09 · conditional · novelty 6.0

Fine-tuning a video generator on a new 17K reasoning-video dataset improves Chain-of-Frame reasoning, and adding learnable visual/textual reasoning tokens yields further gains on external benchmarks.

Modality Forcing for Scalable Spatial Generation

cs.CV · 2026-06-11 · unverdicted · novelty 6.0

Modality Forcing lets a single DiT produce image and depth outputs in any order after training on sparse real-world depth, with larger image-pretrained models yielding better depth accuracy and a 57% AbsRel reduction versus prior joint generative baselines.

Knowledge Transfer Scaling Laws for 3D Medical Imaging

cs.CV · 2026-05-07 · conditional · novelty 6.0

Transfer-aware data allocation derived from observed power-law scaling laws for asymmetric knowledge transfer in 3D medical imaging outperforms standard proportional sampling by up to 58% and generalizes to new budgets.

AstraNav-World: World Model for Foresight Control and Consistency

cs.CV · 2025-12-25 · unverdicted · novelty 6.0

AstraNav-World unifies diffusion video generation and vision-language action planning in a single bidirectional model that improves trajectory accuracy, success rates, and zero-shot real-world adaptation in embodied navigation.

SkyReels-V2: Infinite-length Film Generative Model

cs.CV · 2025-04-17 · unverdicted · novelty 6.0

SkyReels-V2 produces infinite-length film videos via MLLM-based captioning, progressive pretraining, motion RL, and diffusion forcing with non-decreasing noise schedules.
