Researchers have developed a generalization of terminal embeddings that can preserve affine line-segments, overcoming a limitation of previous methods. This advancement enables the creation of dimension-free coresets for time-series clustering using the Fréchet distance. Experiments show these new terminal embeddings perform comparably to Johnson-Lindenstrauss embeddings and favorably against principal component analysis for time-series data. AI
