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...
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 ...

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 ...

The further challenge is to structure light by simultaneously combining more DoFs, for example, a “flying doughnut” pulse as a recent state-of-the-art with a beautiful electromagnetic toroidal configuration in space-time (Fig. 2f), which was observed in an experiment very recently26. The ...
With PCP, ECs predict helix 3 (H3) that is unique to the transition state (Figure 2B) and strand and helix alternatives in the chloride intracellular channel protein (CLIC1) (Figures 2C and S3C). Disorder to 2D and 3D Next, we tested the ability of the method to identify 2D and 3D ...
