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 模型,且可以做到输入输出大小一致。本文实验显示,使用了 SSM 架构的 diffusion model 在任务上的表现...

We have developed a two-dimensional (2-D) face test to determine the stability of a nominally stable linear state-space model being subjected to real structured perturbations. The system matrices are assumed to depend linearly on set of interval parameters. Since the system matrix family of the...

combination with (conditional) diffusion and state-space models, we put forward diverse algorithms, particualary, we propose the generative modelSSSDS4, which is suited to capture long-term dependencies and demonstratesstate-of-the-artresults in time series across diverse missing scenarios and ...
aOur customer is making some changes to the parts to make then stronger. I am expecting new cad models and drawings in the next few days for us to review. 我们的顾客做对零件的一些变动然后使更加加强。 我在今后几天盼望新的cad模型和图画为了我们能回顾。[translate] ...
