Efficient Principal Subspace Projection of Streaming Data Through Fast Similarity Matching

no code implementations6 Aug 2018 Andrea Giovannucci, Victor Minden, Cengiz Pehlevan, Dmitri B. Chklovskii

Big data problems frequently require processing datasets in a streaming fashion, either because all data are available at once but collectively are larger than available memory or because the data intrinsically arrive one data point at a time and must be processed online.

Sparse canonical correlation analysis

no code implementations30 May 2017 Xiaotong Suo, Victor Minden, Bradley Nelson, Robert Tibshirani, Michael Saunders

Canonical correlation analysis was proposed by Hotelling [6] and it measures linear relationship between two multidimensional variables.

Robust and efficient multi-way spectral clustering

1 code implementation27 Sep 2016 Anil Damle, Victor Minden, Lexing Ying

We present a new algorithm for spectral clustering based on a column-pivoted QR factorization that may be directly used for cluster assignment or to provide an initial guess for k-means.

A recursive skeletonization factorization based on strong admissibility

3 code implementations26 Sep 2016 Victor Minden, Kenneth L. Ho, Anil Damle, Lexing Ying

We introduce the strong recursive skeletonization factorization (RS-S), a new approximate matrix factorization based on recursive skeletonization for solving discretizations of linear integral equations associated with elliptic partial differential equations in two and three dimensions (and other matrices with similar hierarchical rank structure).
