Locality Sensitive Hashing in Hyperbolic Space

Chengyuan Deng, Jie Gao, Kevin Lu +2

For a metric space (X,d), a family H of locality sensitive hash functions is called (r,cr,p1​,p2​) sensitive if a randomly chosen function h∈H ha…

Johnson-Lindenstrauss Lemma Beyond Euclidean Geometry

Chengyuan Deng, Jie Gao, Kevin Lu +2

The Johnson-Lindenstrauss (JL) lemma is a cornerstone of dimensionality reduction in Euclidean space, but its applicability to non-Euclidean data has remained limited. This paper e…

Neuc-MDS: Non-Euclidean Multidimensional Scaling Through Bilinear Forms

Chengyuan Deng, Jie Gao, Kevin Lu +3

We introduce Non-Euclidean-MDS (Neuc-MDS), an extension of classical Multidimensional Scaling (MDS) that accommodates non-Euclidean and non-metric inputs. The main idea is to gener…
