He serves on multiple boards, including servings as River Logic’s Board Vice Chairman and Senior Advisor. More and more, business leaders are becoming responsible for understanding how to appropriately leverage business analytics to drive value, both within their business unit as well as companywide. Simply being familiar with the types of business analytics is no longer enough, however; leaders must familiarize themselves with the kinds of problems for which each type of analytics is best suited. Prescriptive analytics is no exception to this. A recent report by Gartner stated the following: “Prescriptive analytics is moving beyond its core community of operations research and management science professionals and becoming increasingly embedded in business applications.” (Hare, J., Swinehart, H., Woodward, A., Forecast Snapshot: Prescriptive Analytics, Worldwide, 2017, Gartner Inc., May 3 2017.) Deemed the most transformational form of advanced analytics, it’s crucial that business leaders understand the value that can be drawn from prescriptive analytics and take responsibility for driving initiatives.

  • Specifying Local Search Neighborhoods from a Constraint Satisfaction Problem Structure
    Specifying Local Search Neighborhoods from a Constraint Satisfaction Problem Structure Mateusz Sla_zy´nski´ 1, Salvador Abreu2, and Grzegorz J. Nalepa1 1 AGH University of Science and Technology, Krakow, Poland fmslaz, [email protected] 2 University of Evora´ and LISP, Evora,´ Portugal [email protected] Abstract Neighborhood operators play a crucial role in defining effec- tive Local Search solvers, allowing one to limit the explored search space and prune the fitness landscape. Still, there is no accepted formal repre- sentation of such operators: they are usually modeled as algorithms in a procedural language, lacking in compositionality and readability. In this paper we propose a new formalization capable of representing several neighborhood operators, thereby eschewing the need to code these in a full Turing complete language. The expressiveness of our proposal stems from a rich problem representation, as used in Constraint Programming models. We compare our system to competing approaches and show a clear increment in expressiveness. 1 Introduction Local Search is a family of heuristic algorithms, typically used to find approxi- mate solutions for hard optimization problems. The common core of those meth- ods consists in finding an initial sub-optimal solution (called configuration in the rest of the paper) and iteratively replacing it with similar configurations, called neighbors. There is a vast body of research on the exploration methods, called metaheuristics, focused mostly on escaping local optima and finding novel configurations. While metaheuristics vary in their performance, they are generic enough to be applicable to many different problems. Various algorithmic configu- ration methods can be used to tune their parameters without human interaction.

  • Introduction to Optimization with Applications in Astronomy and Astrophysics
    Title : will be set by the publisher Editors : will be set by the publisher EAS Publications Series, Vol. ?, 2016 INTRODUCTION TO OPTIMIZATION WITH APPLICATIONS IN ASTRONOMY AND ASTROPHYSICS St´ephaneCanu1, R´emiFlamary2 and David Mary2 Abstract. This chapter aims at providing an introduction to numeri- cal optimization with some applications in astronomy and astrophysics. We provide important preliminary definitions that will guide the reader towards different optimization procedures. We discuss three families of optimization problems and describe numerical algorithms allowing, when this is possible, to solve these problems. For each family, we present in detail simple examples and more involved advanced exam- ples. As a final illustration, we focus on two worked-out examples of optimization applied to astronomical data. The first application is a supervised classification of RR-Lyrae stars. The second one is the de- noising of galactic spectra formulated by means of sparsity inducing models in a redundant dictionary. 1 Optimization in astronomy and astrophysics Optimization can be sketched as the art of finding a `best compromise'. This is a two-step art. The first step translates the problem, the desired objective and possibly some constraints into a mathematical form. The second step finds the best compromise that can be achieved within the framework defined by the first step. In Astrophysics, the information of interest can rarely be observed directly. A first reason for this is that raw data like time series or astronomical images (galaxies, nebulae, cosmological microwave background,...) are only exploitable once corrected for various distortions1 (foreground nuisances sources, atmospheric perturbations, limited resolution of the telescope, instrumental noise sources, etc.).
