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...
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...
Chemical language models (CLMs) – which generate molecules in the form of molecular strings – bear particular promise for this endeavor. Here, we introduce a recent deep learning architecture, termed Structured StateSpace Sequence (S4) model, into de novo drug design. In addition to its ...
While attention-based models are a popular and effective choice in modeling short-range interactions, their performance on tasks requiring long range reasoning has been largely inadequate. In an exciting result, Gu et al. (ICLR 2022) proposed the Structured State SpaceStructured State Space S4 ...

(without a Wiener filter) predict the 3D SIM reconstruction; using DenseDeconNet49, a different type of network; or eliminating the Wiener filter between the sequential 3D RCAN networks. In this work, we built multi-step denoising models for outer mitochondrial membranes (Tomm20), lysosomal ...
“sustainable entrepreneurship” and related terms, the STM method integrated document-specific metadata to enhance the analysis of thematic developments. The findings revealed ten distinct topics, such as innovation in firm performance, sustainability in business models, and the role of education in ...
1 Physical models of 2D- MP-SIM and slice MF-SIM. a-b, 3D spectra of the raw data of 2D-MP-SIM and slice MF-SIM (1st row), where colors indicate aliased frequency components and their corresponding axial cross-sections (2nd row). With the pattern vectors of 2D-MP-SIM or slice MF...
