Tools for BigData Approaches: Numerical Moment Matching and Multi-Layered Parallel Grouping Techniques

Date/Time: November 5th, 3:40 pm
Location: B29 Atanasoff Hall

Abstract:

With the rise of advanced computational power and large-scale database in a broad spectrum of scientific and engineering fields, strong demand emerges especially for novel computational and numerical tools that can facilitate big data-oriented researches. The topic of this talk will be twofold. First, I will present a numerical moment matching technique that is believed to be powerful for representing large-scale irregular population and for incorporating uncertainty behind the real-world big population. This technique will help researchers to foresee how BigData will behave (structurally, economically, biologically, etc.) in conjunction with advanced simulation/prediction models. Next, I will expand upon the multi-layered parallel grouping technique and its successful application to large multi-scale analysis in engineering fields. Notably, a seemingly “super-linear” speedup has been revealed and investigated. This technique is believed to be able to offer unprecedented access to ultimate capacity of parallel computer and to pave a new way to the optimal design of parallel calculations with BigData.
