555-超大规模空间组学高效嵌入框架 SpaLP
from 聊聊Sci
这项研究介绍了一个名为 Local Pooling (LP) 的轻量级超快速计算框架，旨在解决大规模空间组学数据处理中的资源瓶颈。该框架通过创新的邻域索引策略取代了传统的邻接矩阵，使 GPU 显存消耗随细胞数量线性增长，从而能够处理包含千万级细胞的超大规模数据集。基于该框架开发的 SpaLP 工具在各种任务中表现卓越，包括生态位识别、多批次整合以及三维组织图谱构建。实验证明，SpaLP 的计算效率比传统的图形神经网络方法提升了多达 300 倍，且能有效保留全局空间结构。此外，该模型展现出强大的跨平台泛化能力，为开发组学基础模型和推进计算生物学研究提供了高效且通用的解决方案。References: Dai B, Liang Y, Yi L, et al.

Deep Dream State
Neural Nets And Pretty Patterns
Deep Dream State is a full-cast dystopian sci-fi and desire horror audio drama by Neural Nets and Pretty Patterns. As the originating work of desire horror, it locates the uncanny inside wanting itself. While conventional horror positions you against a threat, desire horror implicates you in it. The horror emerges from recognition: the realization of why characters stay, and why surrender feels like relief. Since 2017, the show has used research in dream science, surveillance studies, behavioral economics, and advertising technology to examine systems of control through immersive sound design and full-cast performance.
