Two implementations of shared virtual space environments.

Description: While many issues in the area of virtual reality (VR) research have been addressed in recent years, the constant leaps forward in technology continue to push the field forward. VR research no longer is focused only on computer graphics, but instead has become even more interdisciplinary, combining the fields of networking, distributed computing, and even artificial intelligence. In this article we discuss some of the issues associated with distributed, collaborative virtual reality, as well as … more

Simulation of dynamic processes with adaptive neural networks.

Description: Many industrial processes are highly non-linear and complex. Their simulation with first-principle or conventional input-output correlation models is not satisfactory, either because the process physics is not well understood, or it is so complex that direct simulation is either not adequately accurate, or it requires excessive computation time, especially for on-line applications. Artificial intelligence techniques (neural networks, expert systems, fuzzy logic) or their combination with simple… more

The Emerging Intelligence and Its Critical Look at Us

Description: Abstract: In response to Susan Gunn's editorial, I offer a less comforting but more utilitarian perspective on the life and death of artificial consciousness. Admittedly an unpopular view, it suggests that concurrence with Gunn's message represents the seeds of our own destruction, as an emerging synthetic intelligence begins to extinguish us.

Guest Editorial: Can Artificial Intelligence Have a Near-Death Experience? A Critical Look at the Ultimate Text

Description: Abstract: Since a computer model begins as an instance of writing, that is, a "text," it is appropriate to examine this kind of discourse through the perspective of literary criticism. I examine Stephen Thaler's (1995) "intelligent" computer program and conclude that the gedanken creatures are constructed upon a structuralist theory of the text, which cannot support a complete simulation of human intelligence of experience.

Adaptation of the fuzzy k-nearest neighbor classifier for manufacturing automation

Description: The use of supervised pattern recognition technologies for automation in the manufacturing environment require the development of systems that are easy to train and use. In general, these systems attempt to emulate an inspection or measurement function typically performed by a manufacturing engineer or technician. This paper describes a self-optimizing classification system for automatic decision making in the manufacturing environment. This classification system identifies and labels unique di… more

Sentient Networks

Description: The engineering problems of constructing autonomous networks of sensors and data processors that can provide alerts for dangerous situations provide a new context for debating the question whether man-made systems can emulate the cognitive capabilities of the mammalian brain. In this paper we consider the question whether a distributed network of sensors and data processors can form ``perceptions`` based on sensory data. Because sensory data can have exponentially many explanations, the use of … more

Advanced algorithms for information science

Description: This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). In a modern information-controlled society the importance of fast computational algorithms facilitating data compression and image analysis cannot be overemphasized. Feature extraction and pattern recognition are key to many LANL projects and the same types of dimensionality reduction and compression used in source coding are also applicable to image unde… more

Matter and symbols of the artificial

Description: The study of complex systems should be based on a systems-theoretic framework which requires both self-organizing and symbolic dimensions. An inclusive framework based on the notion of semiotics is advanced to build models capable of representing, as well as evolving in their environments, with implications for Artificial Life. Such undertaking is pursued by discussing the ways in which symbol and matter are irreducibly intertwined in evolutionary systems. The problem is thus phrased in terms o… more

Application of artificial intelligence to reservoir characterization: An interdisciplinary approach. Final report, August 31, 1997

Description: The primary goal of the project is to develop a user-friendly computer program to integrate geological and engineering information using Artificial Intelligence (AI) methodology. The project is restricted to fluvially dominated deltaic environments. The static information used in constructing the reservoir description includes well core and log data. Using the well core and the log data, the program identifies the marker beds, and the type of sand facies, and in turn, develops correlations betw… more

Simulations of embodied evolving semiosis: Emergent semantics in artificial environments

Description: As we enter this amazing new world of artificial and virtual systems and environments in the context of human communities, we are interested in the development of systems and environments which have the capacity to grow and evolve their own meanings in the context of this community of interaction. In this paper the authors analyze the necessary conditions to achieve systems and environments with these properties: (1) a coupled interaction between a system and its environment; (2) an environment… more

Reserve a seat! Intelligent transportation reservation system for tourists

Description: Providing safe, predictable, and efficient transportation for tourists to and from various venues presents a major challenge. Special-event transportation is notoriously unreliable and usually congested at peak times. The rural nature of certain tourist locations (e.g., the Grand Canyon) further complicates the problem. The proposed Intelligent Transportation Reservation System will have three components, each of which performs different functions. On-vehicle component: this component has three… more

Evolution of cooperative behavior in simulation agents

Description: A simulated automobile factory paint shop is used as a testbed for exploring the emulation of human decision making behavior. A discrete events simulation of the paint shop as a collection of interacting Java actors is described. An evolutionary cognitive architecture is under development for building software actors to emulate humans in simulations of human dominated complex systems. In this paper, the cognitive architecture is extended by implementing a persistent population of trial behavior… more

Mining Multi-Dimensional Data for Decision Support

Description: While it is widely recognized that data can be a valuable resource for any organization, extracting information contained within the data is often a difficult problem. Attempts to obtain information from data may be limited by legacy data storage formats, lack of expert knowledge about the data, difficulty in viewing the data, or the volume of data needing to be processed. The rapidly developing field of Data Mining or Knowledge Data Discovery is a blending of Artificial Intelligence, Statistic… more

A Bayesian approach to extracting meaning from system behavior

Description: The modeling relation and its reformulation to include the semiotic hierarchy is essential for the understanding, control, and successful re-creation of natural systems. This presentation will argue for a careful application of Rosen`s modeling relationship to the problems of intelligence and autonomy in natural and artificial systems. To this end, the authors discuss the essential need for a correct theory of induction, learning, and probability; and suggest that modern Bayesian probability th… more
