    We describe a distributed software model for context-aware perception of human activity. The basic building blocks in this model are perceptual modules, composed of a data transformation component and a control component. Modules are assembled into perceptual processes controlled by a reflexive process controller. Process controllers regulate computation, and provide a reflexive description of the...

    We present, first, a hybrid-decision support system where a heuristic-data mining procedure is embedded to the original system. Using Peircean terminology, one of the main roles of this heuristic-data mining method is to evaluate n-ary predicates (i.e., quantitative variables, crisp or vague-fuzzy; and qualitative variables, precise or ambiguous) involved in the different types of decisions and me...

    We examine the function of play as it applies to the autonomy of constructed agents in a dynamic environment. Play happens naturally when there is uncertainty over tasks and outcomes, when there is potential for change, and in open environments or unexplored domain. Jean Piaget's cognitive model of adaptation as a combination of imitation and play will be the starting point of this examination of ... View full abstract»

    Missile defense is moving toward a 'system of systems' approach creating a highly complex scheduling task for the overall battle manager. The battle management segment is responsible with managing all the available sensor resources for engagement planning and utilization of interceptor inventories. This has become a complex, at times intractable effort. To rectify the situation it has been suggest... View full abstract»

    Developing a greenhouse design tool, we realized the convenience of developing a general configurational design model; we called STE (from its composition by specification, translation and evaluation tasks). We present first this general design model, summarizing how it was described using improved versions of some of knowledge modeling tools of the commonKADS methodology. Later, we present STEM, ...

    A band-limited image can be exactly reconstructed from Nyquist samples of that image. However for vision systems that perform a task, such as pattern recognition, there is no requirement to reconstruct the input image. The automatic pattern recognition task may be performed more effectively and more economically when the necessary broadband image information is obtained, with many fewer pixel samp...

    In recent years, clustering became one of the fundamental methods of large dataset analysis. In particular, clustering is an important component of real-time image compression and exploitation algorithms, such as vector quantization, segmentation of SAR, EO/IR, and hyperspectral imagery, group tracking, and behavior pattern analysis. Thus, development of fast scalable real-time clustering algorith... View full abstract»

    In surface scattering model applications a large variety of roughness conditions are encountered: some surfaces may be described with one roughness scale and others with more than one roughness scales; some surfaces are correlated exponentially, Gaussian-like or anywhere between the two. In this study we want to show two backscattering models in algebraic form: (1) a scattering model whose correla... View full abstract»

    The interpretability faculty is a vital element within the framework of intelligent systems [Meystel, A. et al., (2002)]. Central to planning, course of action (COA) and course of action analysis (COAA) emerge in the process of interpretability of heterogeneous information. The purpose is to discuss the interpretability mechanism that can be employed by computing machines to promote intelligent be... View full abstract»

    We apply first order logic (FOL) to formalize the problem of "meaningful generalization", finding the most general and easily interpretable hypotheses. Our software toolkit, LogicMill, is designed to solve this meaningful generalization problem as well as two other related problems: search for a maximal subsystem of mutually independent attributes, and aggregation of the hypotheses in the concise ...

    In small unit operations (SUO), people and equipment work together to meet some mission objective, have distinct roles and information needs, but are often distributed geographically. We describe the SUO Communicator, a combat situation awareness, information management, and communication system for use in small unit operations. The design is agent-based. Key ideas include email-based communicatio... View full abstract»

    Managing and controlling knowledge intensive dynamic systems requires being able to estimate, analyze, and evaluate, under conditions of uncertainty, the existing system and the impact of actions, such as changes in personnel or resources on this system. Our approach to this problem is dynamic network analysis. Using a combination of statistical and simulation tools, we analyze the robustness unde... View full abstract»

    In current practice there is a wide disconnect between increasing availability of sensor data and our ability to apply advanced learning algorithms to process that data in real time. While multitudes of very promising learning algorithms are developed in the research community, years and decades pass before these algorithms become implemented in embedded platforms. We describe a feasibility study ... View full abstract»

    A methodology for resolving collision conflicts of many fast moving robots involving distributed cooperative behavior is proposed. Robots are unaware of the goals and plans of other robots. However, each robot is assumed to know the current states of other robots within a given range of vision. The current state of a robot is represented by its current and target velocities and its heading directi... View full abstract»

    We describe a model of inductive learning of concepts under imprecision by a typoid automaton, which repeats the performance of an adaptive recognizer. We generate a fuzzy model of how children learn step by step from their relatives and teachers to separate - with growing precision - the syntactic elements of a sentence discriminating their function and understanding their semantics. We model the... View full abstract»

    We present a Prolog-based framework for building mobile multi-agent systems. In this framework, a new concept called "field" is introduced. A field provides data and procedures which are written in forms of Prolog program. An agent can "enter" into a field. Multiple agents can enter into one field, and the data and procedures of the field are shared by the agents. Therefore, agents in a field can ... View full abstract»
