DESCRIPTION:Do you interpret your t-SNE embeddings correctly? A perspective
  from map-continuity and leave-one-out. Dr. Zhong will present present evi
 dence that embedding maps of t-SNE\, UMAP and LargeVis can exhibit discont
 inuity points\, leading to unintended topological distortions. To address 
 this\, Dr. Zhong will introduce the leave-one-out (LOO) surrogate that cap
 tures the properties of embedding maps\, 2 types of discontinuity patterns
 \, and two methods to mitigate these issues that help detect out-of-distri
 butions samples in deep learning and assist hyperparameter tuning in singl
 e-cell data analysis.\n\nCONTACT: junjie.hu@wisc.edu\n\nURL: https://biost
