AI总结:

本文综述了Mamba架构,探讨其在基础模型中的应用,分析其在序列长度上的线性可扩展性,并讨论其在不同领域的应用潜力及未来研究方向。

摘要:

作为最具有代表性的深度学习技术之一,Transformer架构已经赋能了许多先进的模型,尤其是包含数十亿参数的大型语言模型(LLMs),成为深度学习的基石。尽管取得了显著成就,但Transformer仍然面临固有的局限性,特别是由于注意力计算的二次计算复杂性导致的推理时间长。最近,一种名为Mamba的新架构,受经典状态空间模型(SSMs)的启发,作为一种有前途的替代方案出现,能够构建基础模型,具有与Transformer相当的建模能力,同时在序列长度上保持接近线性的可扩展性。这引发了越来越多的研究积极探索Mamba在不同领域中的出色表现。鉴于这种快速的发展,迫切需要一个系统性的综述,以整合现有的Mamba赋能模型,提供对这一新兴模型架构的全面理解。在本文的综述中,我们因此深入研究了最近的Mamba相关研究,涵盖三个方面:基于Mamba的模型的进步、将Mamba适应于多样化数据的技术,以及Mamba可以擅长的应用领域。具体而言,我们首先回顾了各种代表性深度学习模型的基础知识以及Mamba-1和Mamba-2的细节作为前提。然后,为了展示Mamba对AI的重要性,我们全面回顾了相关研究,重点探讨Mamba模型的架构设计、数据适应性和应用。最后,我们讨论了当前的局限性,并探索了各种有前途的研究方向,以提供更深入的见解,为未来的研究提供指导。

英文摘要:

As one of the most representative DL techniques, Transformer architecture has empowered numerous advanced models, especially the large language models (LLMs) that comprise billions of parameters, becoming a cornerstone in deep learning. Despite the impressive achievements, Transformers still face inherent limitations, particularly the time-consuming inference resulting from the quadratic computation complexity of attention calculation. Recently, a novel architecture named Mamba, drawing inspiration from classical state space models (SSMs), has emerged as a promising alternative for building foundation models, delivering comparable modeling abilities to Transformers while preserving near-linear scalability concerning sequence length. This has sparked an increasing number of studies actively exploring Mamba's potential to achieve impressive performance across diverse domains. Given such rapid evolution, there is a critical need for a systematic review that consolidates existing Mamba-empowered models, offering a comprehensive understanding of this emerging model architecture. In this survey, we therefore conduct an in-depth investigation of recent Mamba-associated studies, covering three main aspects: the advancements of Mamba-based models, the techniques of adapting Mamba to diverse data, and the applications where Mamba can excel. Specifically, we first review the foundational knowledge of various representative deep learning models and the details of Mamba-1&2 as preliminaries. Then, to showcase the significance of Mamba for AI, we comprehensively review the related studies focusing on Mamba models' architecture design, data adaptability, and applications. Finally, we present a discussion of current limitations and explore various promising research directions to provide deeper insights for future investigations.
