Algorithms for Big Data

Chandra Chekuri

CS498ABD/ABG, Fall 2020

Course Summary

This course will describe some algorithmic techniques developed for handling large amounts of data that is often available in limited ways. Topics that will be covered include data stream algorithms, sampling and sketching techniques, and sparsification, with applications to signals, matrices, and graphs. Emphasis will be on the theoretical aspects of the design and analysis of such algorithms.

This version of the course is directed at senior level undergraduate students and beginning graduate students, and hence will not assume background in randomized algorithms. The pace of the course and the topics will be commensurately adjusted. The previous edition of this course will give a good idea of the topics to be covered although there will be some changes.
