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,作者利用bilinear method做discretization(涉及到解微分方程和...
这篇文章[1]采用了 conditional diffusion model 来做时间序列的 imputation 以及 forecasting 任务。本文的亮点在于,diffusion model 的网络结构不再是 CSDI[2] 中的transformer 结构,而是 structured state-space model(SSM)。我们可以把这种结构理解为 RNN、一维 CNN 以及transformer 的平替结构,都是 seq-to-seq 模...
Here, we introduce a recent deep learning architecture, termed Structured StateSpace Sequence (S4) model, into de novo drug design. In addition to its unprecedented performance in various fields, S4 has shown remarkable capabilities to learn the global properties of sequences. This aspect is ...
In this work, we show that one can match the performance of S4 even without the low rank correction and thus assuming the state matrices to be diagonal. Our Diagonal State SpaceDiagonal State Space (DSS) model matches the performance of S4 on Long Range Arena tasks, speech classification o...

To prove the practical applicability, a full-cell asymmetric solid-state device is fabricated, and it delivered 41.25 Wh/Kg and 750 Wh/Kg energy and power density at 0.5 A/g. The optimum citric acid added Cu2NiSnS4 electrode is shown to be a promising candidate for supercapacitor ...
(2) each rotation is passed through a deep learning model to improve resolution along thexdirection, (3) rotated back to the original frame and (4) Fourier transformed; (5) the maximum value, taken over all rotations, at each spatial frequency was recorded and, finally, (6) inverse ...
