Hierarchical clustering

F Nielsen, F Nielsen - Introduction to HPC with MPI for Data Science, 2016 - Springer
Agglomerative hierarchical clustering differs from partition-based clustering since it builds a
binary merge tree starting from leaves that contain data elements to the root that contains the …

On learning mixtures of well-separated gaussians

O Regev, A Vijayaraghavan - 2017 IEEE 58th Annual …, 2017 - ieeexplore.ieee.org
We consider the problem of efficiently learning mixtures of a large number of spherical
Gaussians, when the components of the mixture are well separated. In the most basic form …

Partitioning well-clustered graphs: Spectral clustering works!

R Peng, H Sun, L Zanetti - Conference on learning theory, 2015 - proceedings.mlr.press
