Stock Market Prediction Using Different Neural Network Classification Architectures, Karsten Schierholt, Cihan H. Dagli

Engineering Management and Systems Engineering Faculty Research & Creative Works

In recent years, many attempts have been made to predict the behavior of bonds, currencies, stocks, or stock markets. The Standard and Poors 500 Index is modeled using different neural network classification architectures. Most previous experiments used multilayer perceptrons for stock market forecasting. A multilayer perceptron architecture and a probabilistic neural network are used to predict the incline, decline, or steadiness of the index. The results of trading with the advice given by the network is then compared with the maximum possible performance and the performance of the index. Results show that both networks can be trained to perform better …

The Application Of Markov State Probabilities In Developing Artificially Intelligent Managerial Strategies: A Case Study Based On Major League Baseball, Arnold Vincent Arconati

Doctoral Dissertations

"Baseball is a very large industry that influences the lives and financial assets of millions of people.

Many baseball analysts estimate that even the best Major League player can increase his team's expected number of yearly wins by only 3 or 4 games. In 1993 Bobby Bonilla, a New York Mets National League outfielder, earned $5,200,000 more than the average Major League player earned. The Mets apparently believed that expenditure of this money was worth his expected additional victories. If the strategy of an Artificially Intelligent baseball manager could produce 4 more team victories than the corresponding human baseball manager, …

The Integration Of Simulation And Reality For Education Enhancement And Training, Clarence Rasquinha, Stephen A. Raper

Engineering Management and Systems Engineering Faculty Research & Creative Works

Quite often, when engineers are exposed to a manufacturing environment on the job for the first time, they undergo a baptism by fire. The environment forces them to deal with situations that integrate many different bodies of knowledge. Reliance on concepts acquired in the academic environment is crucial to their success. Unfortunately, lacking in most academic environments, is any experience through which some or all of these concepts are integrated. In a continuing effort to enhance educational practices in Manufucturing/Systems Engineering programs and perhaps improve the preparedness of a young engineer, the CITE (Computer Integrated Technological Enterprise) tool offers educators …

A Model Of Electronic Warfare Systems Acquisition And Engineering For Saudi Arabia, Negaa M. Albegami

Doctoral Dissertations

"A major activity within the systems engineering process is the requirements definition and analysis phase. In technical systems, planning this phase looks too technical for top management and too broad for the engineers specialized in narrow technical fields. This categorization (too technical/too broad) represents a gap between top management and specialized engineering. In Saudi Arabia, such a gap is believed to be very wide.

The main objective of this research is to find a way to narrow this gap between management and engineering when planning government systems, especially in electronic warfare (EW) systems. A solution in this effort is to …

A Methodology For Customer Requirements Generation In Communication Systems Planning, Negaa Albegami, Yildirim Omurtag

Engineering Management and Systems Engineering Faculty Research & Creative Works

In electronic communication systems it is nearly impossible to keep up with changing technology. This problem is further aggregated in the developing countries where the contractor (probably a western company) is expected to develop the system from the ground up. A basic problem which confronts this approach is either: 1) The customer will start adding or rejecting some of the capabilities, or 2) The local operation will never use some of the capabilities. Both of these outcomes are costly in terms of time and resources available to a developing country. This paper describes a new methodology for requirements generation to …

Coordinated Strategic Planning Of Hydroelectric Energy Usage Using Stochastic Dynamic Programming With Decoupled Production Cost Simulation, Duane David Highley

Masters Theses

"The method of Stochastic Dynamic Programming is applied to the problem of Long-term hydrothermal coordination for a five-reservoir system in the Midwest. The model that has been developed will optimize the monthly reservoir elevations to produce the lowest expected energy production cost. The production cost calculations are decoupled from the Dynamic Programming loop, resulting in shorter execution times. Constraints are included for maximum and minimum reservoir elevations, maximum monthly reservoir rise and drop, and maximum and minimum monthly energy production. These constraints help to reduce the state space and shorten execution time. An additional constraint is modeled to control the …
