Grab it Explore online k-means clustering for arbitrary data streams in this 37-minute USC Probability and Statistics Seminar talk by Robi Bhattacharjee. Delve into a novel approach for achieving clustering loss that is comparable to the best possible loss using k fixed points in hindsight. Learn about a proposed data parameter, Λ(X), and its implications for algorithm performance. Discover a randomized algorithm that achieves O(Λ(X)+L(X,OPTk)) clustering loss while maintaining O(kpoly(logn)) memory and cluster centers. Understand how this algorithm achieves polynomial space and time complexity without making assumptions on input data. Follow the presentation through key concepts including the online setting, lower bounds, streaming challenges, and innovative ideas for center management and point deletion. Gain insights into future directions for research in this field.
