Embedding high-dimensional data into (non-)Euclidean spaces (fast)

By Martin Skrodzki

Also appears in collection : 2026 - T1 - WS2 - Bridging visualization and understanding in Geometry and Topology

The field of explorative data analysis provides methods to investigate large, potentially high-dimensional, data sets. Such exploration is best done visually, to engage the human in the loop with all pattern recognition built into our visual cortex. In my talk, I will give a brief introduction to dimensionality reduction for this purpose, especially about the t-SNE method. I will then show how embedding into non-Euclidean spaces can provide embeddings that help with visual inspection and how to compute such embeddings quickly.
