Albert Gu and Tri Daohttps://arxiv.org/pdf/2312.00752 学习Mamba之前呢,不妨了解一下S4,他们都有一个共同的作者Albert Gu 。 State Space Model 首先,state space model可以定义成下式 x′(t)=Ax(t)+Bu(t)y(t)=Cx(t)+Du(t) 其中x是state vector, u为input,y为output,D视为0矩阵。 在文章中,...
就像Ashish VASWANI等人(2017)所写的论文Attention is all you nee一样,S4是新型神经网络架构的基础,但不是在实践中使用的模型(有其他性能更好或更容易实现的SSM)。在此之前,先简单介绍SSM的基础知识。 SSM(State Space Model,状态空间模型)是一种用于描述时间序列数据的统计模型。它广泛应用于机器学习和统计学中,...

四、S4 (Structured State Space Model) S4 是 HiPPO 的后续工作,论文名称为:Efficiently Modeling Long Sequences with Structured State Spaces。 S4 的主要工作是将 HiPPO 中的矩阵 A(称为 HiPPO 矩阵)转换为正规矩阵(正规矩阵可以分解为对角矩阵)和低秩矩阵的和,以此提高计算效率。 S4 通过这种分解,将计算复杂...

In a Structured State Space Model (S4), the matricesA,B, andCare independent of the input since their dimensionsNandDare static and do not change. Instead, Mamba makes matricesBandC,and even thestep size∆,dependent on the input by incorporating the sequence length and batch size of the ...
We propose the Structured State Space sequence model (S4) based on a new parameterization for the SSM, and show that it can be computed much more efficiently than prior approaches while preserving their theoretical strengths. Our technique involves conditioning \( A \) with a low-rank ...

For a model with a finite state space, test cases would be generated directly from this machine, without needing further adjustment. However, since the test space of this sample model is infinite, it must be sliced in the Cord script before generating tests. The static model template provides...
