新的CADENCE框架可从稀疏数据预测个体动态

研究人员开发了CADENCE,一个新颖的概率框架,旨在从极其稀疏的数据快照中推断连续的个体轨迹。该方法克服了现有方法的局限性,这些方法要么需要密集的纵向数据,要么在分析横断面数据时会丢失个体动态。CADENCE将潜在动态锚定到静态的、个体层面的上下文,为单时间点轨迹推断提供了可识别性保证。该框架结合了基于分数的空间编码器和软专家混合路由器,以联合识别个体动态参数和路由函数。在包括生物数据在内的各种基准测试中,CADENCE的表现与在密集数据上训练的顺序模型相当或更优。 AI

影响 能够用有限的数据更准确地模拟动态系统,可能对从生物学到物理学的领域产生影响。
