模型结构:将原始DiffWave中的双向膨胀卷积层用S4层代替,即在加入扩散embedding后,我们在每个残差块中使用S4作为扩散层。同时,在与条件信息相加后引入第二个S4层,这赋予模型在合并输入和条件信息之后更大的灵活性。图2画出了它的结构。 损失函数: 和DDPM里的一样 训练伪代码: 输入:扩散模型超参数 \beta\in[\beta...
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...

S4 Experiments This section describes how to use the latest S4 model and reproduce experiments immediately. More detailed descriptions of the infrastructure are in the subsequent sections. Structured State Space (S4) The S4 module is found at src/models/sequence/ss/s4.py. For users who would lik...
Consequently, the former can support low surface tension liquids in the Cassie state resulting in superoleophobic surface. The substrates possessing a predominantly spherical textures (Set C and Set D) demonstrated intermedi- ate superoleophobic behavior between the hierarchical and one scale textured. ...

In particular, the SSM kernel is particularly sensitive to the (A,B) (and sometimes Δ parameters), so the learning rate on these parameters is sometimes lowered and the weight decay is always set to 0.See the method register in the model (e.g. s4d.py) and the function setup_...

The triple exponential fitting model is not good enough in some cases. Thus, we should additionally consider the processes of trapping and de-trapping [14]. Photovoltage decay transients of the solar cells fabricated on different perovskite films are depicted in Figure 9. The photovoltage reaches ...
More integrated solutions are needed that connect different areas and, thus, generate a change in the model of life that allows guaranteeing the future of the planet and the permanence of the human beings in a sustainable way. One of the first steps to launch the search for solutions to ...
