What you can do with Coordinated Samples
Edith Cohen, Haim Kaplan
Sample coordination, where similar instances have similar samples, was proposed by statisticians four decades ago as a way to maximize overlap in repeated surveys. Coordinated samp…
Get the Most out of Your Sample: Optimal Unbiased Estimators using Partial Information
Edith Cohen, Haim Kaplan
Random sampling is an essential tool in the processing and transmission of data. It is used to summarize data too large to store or manipulate and meet resource constraints on band…
Coordinated Weighted Sampling for Estimating Aggregates Over Multiple Weight Assignments
Edith Cohen, Haim Kaplan, Subhabrata Sen
Many data sources are naturally modeled by multiple weight assignments over a set of keys: snapshots of an evolving database at multiple points in time, measurements collected over…
Leveraging Discarded Samples for Tighter Estimation of Multiple-Set Aggregates
Edith Cohen, Haim Kaplan
Many datasets such as market basket data, text or hypertext documents, and sensor observations recorded in different locations or time periods, are modeled as a collection of sets…
Sketch-Based Estimation of Subpopulation-Weight
Edith Cohen, Haim Kaplan
Summaries of massive data sets support approximate query processing over the original data. A basic aggregate over a set of records is the weight of subpopulations specified as a p…
