Evaluating Hedge Fund and CTA Performance: Data Envelopment by Greg N. Gregoriou

By Greg N. Gregoriou

Introducing info Envelopment research (DEA) -- a quantitative method of check the functionality of hedge cash, money of hedge money, and commmodity buying and selling advisors.  Steep your self during this process with this crucial new publication by way of Greg Gregoriou and Joe Zhu.

''This ebook steps past the conventional trade-off among unmarried variables for possibility and go back within the selection of funding portfolios. For the 1st time, a entire strategy is gifted to compose portfolios utilizing a number of measures of chance and go back concurrently. This procedure represents a watershed in portfolio building suggestions and is mainly helpful for hedge fund and CTA offerings.'' -- Richard E.

Grid Computing: A Practical Guide To Technology and by Ahmar Abbas

By Ahmar Abbas

As a rule conversing, grid computing seeks to unify geographically dispersed computing structures to create one huge, strong approach. during the last two decades, grid computing has had a comparatively small impression on company productiveness, as a result of the titanic funding it required to set up and retain it. This has significantly replaced during the last 12 months because of technological developments within the undefined. various businesses, together with IBM and solar, have began maximizing grid computing to complete initiatives speedier and less expensive, and the productiveness profits were superb. If the fashion maintains, all IT execs should have a fantastic figuring out of grid computing expertise which will stay aggressive of their box. This e-book presents IT pros with a transparent, readable, and pragmatic review to all facets of grid computing know-how, with hands-on guidance on imposing a practicable grid-computing approach. starting with an intensive heritage of the know-how, the e-book then delves into the most important elements together with protection, net companies, sensor grids, information grids, globus, and masses extra. The final element of the ebook is dedicated to making industry-specific grid computing purposes. during the booklet are a variety of contributed chapters from grid computing specialists.

The Regularized Fast Hartley Transform: Optimal Formulation by Keith Jones

By Keith Jones

When designing high-performance DSP platforms for implementation with silicon-based computing know-how, the oft-encountered challenge of the real-data DFT is usually addressed by means of exploiting an latest complex-data FFT, which could simply bring about an excessively complicated and resource-hungry answer. The examine defined in The Regularized quick Hartley rework: optimum formula of Real-Data quickly Fourier remodel for Silicon-Based Implementation in Resource-Constrained Environments bargains with the matter by means of exploiting at once the real-valued nature of the information and is focused at these real-world functions, corresponding to cellular communications, the place measurement and gear constraints play key roles within the layout and implementation of an optimum resolution. The Regularized quick Hartley rework provides the reader with the instruments essential to either comprehend the proposed new formula and to enforce uncomplicated layout adaptations that provide transparent implementational benefits, either useful and theoretical, over extra traditional complex-data options to the matter. The highly-parallel formula defined is proven to guide to scalable and device-independent strategies to the latency-constrained model of the matter that are in a position to optimize using the on hand silicon assets, and therefore to maximise the plausible computational density, thereby making the answer a real develop within the layout and implementation of high-performance parallel FFT algorithms.

Optimizing the parSOM Neural Network Implementation for Data by Tomsich P., Rauber A., Merkl D.

By Tomsich P., Rauber A., Merkl D.

The self-organizing map is a admired unsupervised neural community version which lends itself to the research of high-dimensional enter information and knowledge mining functions. even though, the excessive execution instances required to coach the map placed a restrict to its program in lots of high-performance info research software domains.In this paper we talk about the /orSOM implementation, a software-based parallel implementation of the self-organizing map, and its optimization for the research of high-dimensional enter info utilizing allotted reminiscence structures and clusters. the unique /orSOM set of rules scales rather well in a parallel execution atmosphere with low communique latencies and exploits parallelism to deal with reminiscence latencies. but it suffers from bad scalability on dispensed reminiscence desktops. We current optimizations to extra decouple the subprocesses, simplify the verbal exchange version and enhance the portability' of the process.
