By Santosh S. Vempala

Random projection is a straightforward geometric approach for decreasing the dimensionality of a collection of issues in Euclidean house whereas maintaining pairwise distances nearly. The process performs a key function in different step forward advancements within the box of algorithms. In different circumstances, it offers based substitute proofs. The ebook starts with an trouble-free description of the process and its simple homes. Then it develops the tactic within the context of purposes, that are divided into 3 teams. the 1st staff comprises combinatorial optimization difficulties comparable to maxcut, graph coloring, minimal multicut, graph bandwidth and VLSI format. awarded during this context is the idea of Euclidean embeddings of graphs. the following team is computer studying difficulties, particularly, studying intersections of halfspaces and studying huge margin hypotheses. The projection process is additional subtle for the latter program. The final set includes difficulties encouraged by means of info retrieval, particularly, nearest neighbor seek, geometric clustering and effective low-rank approximation. inspired by means of the 1st functions, an extension of random projection to the hypercube is built the following. through the e-book, random projection is used with a purpose to comprehend, simplify and attach development on those vital and probably unrelated difficulties. The publication is acceptable for graduate scholars and learn mathematicians drawn to computational geometry.
