Metric -clustering using only Weak Comparison Oracles
Rahul Raychaudhury, Aryan Esmailpour, Sainyam Galhotra +1
Clustering is a fundamental primitive in unsupervised learning. However, classical algorithms for -clustering (such as -median and -means) assume access to exact pairwise…
Subset Sampling over Joins
Aryan Esmailpour, Xiao Hu, Jinchao Huang +1
Subset sampling (also known as Poisson sampling), where the decision to include any specific element in the sample is made independently of all others, is a fundamental primitive i…
Space-Time Tradeoffs for Spatial Conjunctive Queries
Aryan Esmailpour, Xiao Hu, Stavros Sintos
Given a conjunctive query and a database instance, we aim to develop an index that can efficiently answer spatial queries on the results of a conjunctive query. We are interested i…
A Theoretical Framework for Distribution-Aware Dataset Search
Aryan Esmailpour, Sainyam Galhotra, Rahul Raychaudhury +1
Effective data discovery is a cornerstone of modern data-driven decision-making. Yet, identifying datasets with specific distributional characteristics, such as percentiles or pref…
