English(EN) ibUMAP: Coherent and Scalable Field Evaluation for UMAP Optimization

ibUMAP 提供更快、更稳定的 UMAP 嵌入

研究人员开发了 ibUMAP,一种用于优化 Uniform Manifold Approximation and Projection (UMAP) 嵌入的新方法。与使用随机负采样的传统 UMAP 不同,ibUMAP 采用基于连贯场的方​​法,该方法从共享嵌入快照中同步评估吸引力和排斥力。该方法利用基于插值的 FFT 方案,可在 CPU 和 GPU 上进行高效评估,从而比现有实现显着加快速度。新方法还提供了更高的运行稳定性,并在局部-全局保真度方面提供了可衡量的权衡。 AI

影响 提供了一种更稳定、更有效的方法来生成嵌入,有可能改进下游机器学习任务。
