📝 摘要(中文)
随着具身人工智能的发展,端到端控制策略如视觉-语言-动作(VLA)模型已成为主流。然而,现有VLA模型面临高昂的计算和存储成本,需要优化。量化被认为是降低内存成本和加速计算的有效方法,但现有量化方法在VLA模型中应用受限于令牌对齐问题。为此,本文提出了一种名为EaqVLA的优化框架,采用编码对齐量化。通过完整的分析方法识别不同粒度的错位,基于分析结果提出了考虑编码对齐的混合精度量化。实验表明,EaqVLA在端到端动作控制中实现了更好的量化性能,量化损失最小,并且加速效果显著。

📄 摘要(原文)
With the development of Embodied Artificial intelligence, the end-to-end control policy such as Vision-Language-Action (VLA) model has become the mainstream. Existing VLA models faces expensive computing/storage cost, which need to be optimized. Quantization is considered as the most effective method which can not only reduce the memory cost but also achieve computation acceleration. However, we find the token alignment of VLA models hinders the application of existing quantization methods. To address this, we proposed an optimized framework called EaqVLA, which apply encoding-aligned quantization to VLA models. Specifically, we propose an complete analysis method to find the misalignment in various granularity. Based on the analysis results, we propose a mixed precision quantization with the awareness of encoding alignment. Experiments shows that the porposed EaqVLA achieves better quantization performance (with the minimal quantization loss for end-to-end action control and xxx times acceleration) than existing quantization methods.
