AI总结:

VILA-U是一个统一基础模型,通过单一自回归下一个token预测框架同时实现视觉与语言的理解与生成,省去扩散模型等额外组件,在简化结构的同时达到接近SOTA的性能。

摘要:

VILA-U是一个统一的基础模型,集成了视频、图像、语言的理解和生成。传统的视觉语言模型(VLMs)使用分离的模块来理解和生成视觉内容,这可能导致不对齐并增加复杂性。相比之下,VILA-U为这两项任务采用单一的自回归下一个token预测框架,消除了对扩散模型等额外组件的需求。这种方法不仅简化了模型,还在视觉语言理解和生成方面达到了接近最先进的性能。VILA-U的成功归因于两个主要因素:在预训练期间将离散视觉token与文本输入对齐的统一视觉塔,这增强了视觉感知;以及自回归图像生成在使用高质量数据集时能够达到与扩散模型相似的质量。这使得VILA-U能够使用完全基于token的自回归框架,表现出与更复杂模型相当的性能。

英文摘要:

VILA-U is a Unified foundation model that integrates Video, Image, Language understanding and generation. Traditional visual language models (VLMs) use separate modules for understanding and generating visual content, which can lead to misalignment and increased complexity. In contrast, VILA-U employs a single autoregressive next-token prediction framework for both tasks, eliminating the need for additional components like diffusion models. This approach not only simplifies the model but also achieves near state-of-the-art performance in visual language understanding and generation. The success of VILA-U is attributed to two main factors: the unified vision tower that aligns discrete visual tokens with textual inputs during pretraining, which enhances visual perception, and autoregressive image generation can achieve similar quality as diffusion models with high-quality dataset. This allows VILA-U to perform comparably to more complex models using a fully token-based autoregressive framework.
