本文提出Mask-LLaVA框架,通过结合多级视觉特征,实现更高效的视觉语言模型,减少标记数量的同时保持性能。

摘要:

当前自回归视觉语言模型(VLMs)通常依赖大量的视觉标记来表示图像,这导致在推理时间需要更多的计算资源。为了解决这个问题,我们提出了Mask-LLaVA,一个框架,利用不同层次的视觉特征来为自回归VLMs创建紧凑且信息丰富的视觉表示。具体来说,我们结合基于掩码的对象表示与全局标记和局部补丁标记。虽然所有标记都在训练过程中被使用,但结果显示,所得到的模型可以在测试时灵活地减少尤其是基于掩码的对象标记的数量,允许在推理过程中动态调整标记数量而无需重新训练模型,且不会显著降低性能。我们在一系列标准基准上评估了所提出的方法,结果显示与当前标记高效方法相当,并与仅使用少量视觉标记的原始LLaVA基线相当。我们的分析表明,结合多级特征可以实现更少标记的高效学习,同时在测试时允许动态选择标记以获得良好的性能。

英文摘要:

Current autoregressive Vision Language Models (VLMs) usually rely on a large number of visual tokens to represent images, resulting in a need for more compute especially at inference time. To address this problem, we propose Mask-LLaVA, a framework that leverages different levels of visual features to create a compact yet information-rich visual representation for autoregressive VLMs. Namely, we combine mask-based object representations together with global tokens and local patch tokens. While all tokens are used during training, it shows that the resulting model can flexibly drop especially the number of mask-based object-tokens at test time, allowing to adapt the number of tokens during inference without the need to retrain the model and without a significant drop in performance. We evaluate the proposed approach on a suite of standard benchmarks showing results competitive to current token efficient methods and comparable to the original LLaVA baseline using only a fraction of visual tokens. Our analysis demonstrates that combining multi-level features enables efficient learning with fewer tokens while allowing dynamic token selection at test time for good performance.
