This article compares a neural network-based controller, both local and global networks, with fuzzy associative memories (FAM) on a nonlinear problem. CMAC and FAM are chosen as representatives of local generalization networks. CMAC controller is trained off-line, therefore, it can response to the incoming input immediately. CMAC can interpolate its memory and give a reasonable control signal even the input has not been trained on. Backpropagation is picked as a representative of global generalization networks. All three systems are studied on a simple simulated control problem. This preliminary research will be adapted later to control the laser cutting machine. A …


A Hierarchial Neural Network Implementation For Forecasting, B. Fulkerson, M. A. Ozbayoglu, Cihan H. Dagli Jan 1994

A Hierarchial Neural Network Implementation For Forecasting, B. Fulkerson, M. A. Ozbayoglu, Cihan H. Dagli

In this paper, a hierarchical neural network architecture for forecasting time series is presented. The architecture is composed of two hierarchical levels using a maximum likelihood competitive learning algorithm. The first level of the system has three experts each using backpropagation and a gating network to partition the input space in order to map the input vectors to the output vectors. The second level of the hierarchical network has an expert using fuzzy ART for producing the correct trend coming from the first level. The experiments show that the resulting network is capable of forecasting the changes in the input …

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 …


Effectiveness Of A Multimedia Televised Distance Education Program For Engineering Majors, Bonnie Daily, Madison Daily Jan 1994

Effectiveness Of A Multimedia Televised Distance Education Program For Engineering Majors, Bonnie Daily, Madison Daily

Engineering Management and Systems Engineering Faculty Research & Creative Works

The University of Missouri‐Rolla, the state's, "technological university," has proposed a televised distance education program that would originate on the UMR campus and be delivered to community colleges and four‐year institutions within the state not now offering engineering. The program would include the use of computer‐integrated multimedia classrooms at both the home site and remote sites and would permit two‐way transmission of video, audio, and data. Student response units would also be used at both sites to permit immediate feedback from the students to the instructor. Due to the cost of this proposal, it was determined a pilot study would …


Ai-Based Generation Of Production Engineering Labor Standards, Hulya Yazici, Colin Othniel Benjamin, James Mcglaughlin Jan 1994

Ai-Based Generation Of Production Engineering Labor Standards, Hulya Yazici, Colin Othniel Benjamin, James Mcglaughlin

Increased automation of manufacturing is necessary to compete in today's worldwide markets. The role of artificial intelligence (AI) techniques for incorporating the automation with changing manufacturing environments needs to be investigated. Al techniques can assist in meeting the challenge of transforming shop floor production engineering data into appropriate production engineering labor standards in a timely, consistent, and cost-effective manner. Production heuristics can be incorporated into an expert system that can learn from the changing manufacturing environment. This paper presents a prototype expert system which transfers the knowledge of experienced methods engineers into a rule-based system to develop the appropriate job …
