Online Adaptive Mahalanobis Distance Estimation

no code implementations2 Sep 2023 Lianke Qin, Aravind Reddy, Zhao Song

Mahalanobis metrics are widely used in machine learning in conjunction with methods like $k$-nearest neighbors, $k$-means clustering, and $k$-medians clustering.

Adaptive and Dynamic Multi-Resolution Hashing for Pairwise Summations

no code implementations21 Dec 2022 Lianke Qin, Aravind Reddy, Zhao Song, Zhaozhuo Xu, Danyang Zhuo

In this paper, we propose Adam-Hash: an adaptive and dynamic multi-resolution hashing data-structure for fast pairwise summation estimation.

Online MAP Inference and Learning for Nonsymmetric Determinantal Point Processes

no code implementations29 Nov 2021 Aravind Reddy, Ryan A. Rossi, Zhao Song, Anup Rao, Tung Mai, Nedim Lipka, Gang Wu, Eunyee Koh, Nesreen Ahmed

In this paper, we introduce the online and streaming MAP inference and learning problems for Non-symmetric Determinantal Point Processes (NDPPs) where data points arrive in an arbitrary order and the algorithms are constrained to use a single-pass over the data as well as sub-linear memory.

Beyond Perturbation Stability: LP Recovery Guarantees for MAP Inference on Noisy Stable Instances

no code implementations26 Feb 2021 Hunter Lang, Aravind Reddy, David Sontag, Aravindan Vijayaraghavan

Several works have shown that perturbation stable instances of the MAP inference problem in Potts models can be solved exactly using a natural linear programming (LP) relaxation.

Improved Guarantees for k-means++ and k-means++ Parallel

no code implementations NeurIPS 2020 Konstantin Makarychev, Aravind Reddy, Liren Shan

In this paper, we study k-means++ and k-means++ parallel, the two most popular algorithms for the classic k-means clustering problem.
