This survey highlights the recent advances in algorithms for numerical linear algebra that have come from the technique of linear sketching, whereby given an n X d matrix A, one first compresses A to an m X d matrix S - A, where S is a certain m X n random matrix with m " n. Much of the expensive computation is then performed on S - A, thereby accelerating the solution for the original problem involving A. This book considers least squares as well as robust regression problems, low rank approximation, and spectral sparsification. It also discusses a number of variants of these problems. Finally, it discusses the limitations of this method.
This collection of Stephen Leacock classic works includes the following titles: The Hostelry of Mr. Smith, The Speculations of Jefferson Thorpe , The Marine Excursion of the Knights of Pythias, The Ministrations of the Rev. Mr. Drone, and many more.
A 100 page sketch pad that has framed layouts which connect to the children's picture book titled "The Adventures of Zooky the Terrier, What Can A Dog Do?." As part of the Zooky and Friends collection, this drawing book is meant to inspire imagination, fun and creativity. The BONUS feature is a section in the back of the book which includes some of the original sketch ideas that inspired the final Zooky characters. www.zookytheterrier.com
