TriMap: Large-scale Dimensionality Reduction Using Triplets

Cited by: 9|Views15

Abstract:

We introduce ``TriMap''; a dimensionality reduction technique based on triplet constraints that preserves the global accuracy of the data better than the other commonly used methods such as t-SNE, LargeVis, and UMAP. To quantify the global accuracy, we introduce a score which roughly reflects the relative placement of the clusters rathe...More
