As the complexity of such systems grows, the design of agent societies with a complete pre-defined behaviour is a significant challenge due to the dynamic interactions among agents and between agents and the environment. To overcome existing difficulties, agent systems with emergent behaviour are a fertile area of research and span a large range of applications. The paper presents an analysis of the anticipatory capabilities of multi-agent systems endowed with emergent behaviour, by considering both reactive multi-agent systems and cognitive multi-agent systems. Our approach in analysis is driven by the different levels on which predicted behaviour can be achieved and is illustrated by two scenarios, one for each case of agent system, grounding the view for the cognitive case in our previous related work on self-organizing systems with cognitive agents.

As concentrated (discrete, ordinary differential equations) as distributed ( electromagnetic theory equations, cellular automata) systems with anticipation had been considered earlier. But further development of the theory of anticipatory systems depends on the investigations of new examples of distributed in space systems with anticipation. So in proposed paper the new examples of distributed physical models with anticipation had been considered - namely the system of hyperbolic differential equations with special boundary conditions. It is proposed the mathematical formulation of problems, possible analytical formulas for solutions and interpretations of presumable distributed solutions. Complex behavior of such solutions is discussed. A list of further research problems is proposed.

The agent is equipped with a recurrent neural network, and by controlling the dynamics of the interacting system, it should predict its state in one-step prediction. To quantitatively characterize the interaction modality between the agent and the interacting system, we used transfer entropy. As a result, by varying the nonlinear parameter of the interacting system and the coupling strength, we numerically show that the adaptation dynamics can be distinguished between an agent-driven and a non-agent-driven dynamics.

In practical computing anticipatory systems, the efficiency of anticipatory reasoning engine is a key issue to satisfy the real-time requirements from applications. FreeEnCal: a forward reasoning engine for general-purpose purpose is a hopeful candidate for anticipatory reasoning engines. However, the current FreeEnCaJ is not efficient enough for practical computing anticipatory systems. This paper presents a new implementation of FreeEnCal improved by adopting fast algorithms, and shows its efficiency by comparing the improved FreeEnCal with the old one. The improved FreeEnCal can be used as an anticipatory reasoning engine of practical computing anticipatory systems.

Because some of the foregoing factors are probabilistic in nature and operate over time, the software reliability models are formulated in terms of random processes. The paper investigates the anticipatory property of software reliability models, focusing on the geometric family of reliability models.

At present, there is no engineering environment to support development and maintenance of anticipatory reasoning-reacting systems. This paper presents a development and maintenance environment we are building for developing and maintaining anticipatory reasoning-reacting systems. By using our development and maintenance environment, developers and maintainers can develop and maintain various practical anticipatory reasoning-reacting systems more easily.

The dataset analysed is a part of a cohort study which principally focused on a fatigue syndrome of the elementary and junior high school educatees. In the classifier analysis we employed a major supervised machine-learning algorithm, K-nearest Neighbour (K-NN), coupled with Principal Component Analysis (PCA). As a result, the performance that was found by the classifier analysis provides rather better results than that of the regression analysis. Finally we discussed the availability of both analyses with referring to the technical and conceptual limitation of both approaches.

It can be immediately noticed some analogy with other systems of the brain, namely with reticular ascending activating system which is formed by networks of cells and their connections, each one responding to multiple sensory heterogeneous efferents. Nevertheless there are some remarkable differences between the two types of multisensory convergence namely the level of representation of associative multisensory systems is more elaborate, more precise and implies a higher level of differentiated abstraction than it is the case with cells of the reticular system witch serve only functions of arousal of the brain or control of the sleep-wakefulness system or attention. We show that the processing of EEG and ERPs signals by the Lee detection method and then by Fourier analysis can be used to identify high abstraction level cognitive processes and emotional states. Finally we present some examples of application of Lee method to ERP and EEG records.

Among many cognitive biases proposed, we focus on two symmetrical biases: symmetry and mutual exclusivity bias. Implementing the two biases in a probabilistic framework on covariation information, we test our loosely symmetric (LS) model in word learning tasks, in comparison with the ordinary conditional probability and the totally symmetric/biased probability. LS is shown to break a trade-off in the three tasks. It is argued t hat LS is a model of development in the sense of Vygotsky, where top-down/deductive and bottom-up/inductive processes crisscross.

Because neural networks usually employ continuously distributed representation for state space, learning newly added data affects the existing memories. We apply a neural network with algebraic (lattice) structure to incremental learning, that has been proposed to model information processing in the dendrites of neurons. It has been proposed as a mathematical model of information processing in the dendrites of neurons. Because of the operation 'maximum' in lattice algebra weakening the continuously distributed representation, our proposed model succeeds in incremental learning.

We show that a pertinent study of human consciousness should be a pluri-disciplinary approach through Biochemistry, Biology, Biosemiotics, Cybernetics and Artificial Intelligence (A.I.), Language and Logic, Nanochemistry, Neurochemistry, Physics, Psychology. We ask many questions from relevant perspectives to scientific researchers.

I.A. does not depend on external environment, our sense organs, and our cognitions. This ground state of consciousness is timeless and irreducible to sub-constituents; therefore reductionism can apply neither to the analysis nor to the new theory of I.A. The methodology for investigating I.A. is proposed and the relation between I.A. and the hard problem in consciousness proposed by Chalmers is discussed.

Depending on the respective viewpoint, we may either say that the conscious now is moving through the once-and-for-all fixed space-time universe, or we may say that the space-time universe is moving through the constant now. In this article I try to explain the "subjective illusion" of dynamical flow on the basis of a static space-time universe as it is suggested by relativity theory. The conceptual toolkit for this undertaking is provided by the philosophy of spacetime holism, which I have suggested as a useful approach to a variety of problems. While the argument has already been developed in an earlier publication from a more technical point of view, this article concentrates on the experiential aspects of the involved concepts.

It follows a briefly presentation of the essential characteristics of languages and geometry to discover their main similarities in the domain of knowledge transfer. The waves are the essential language vehicles: sounds or vocal waves for conversations and lectures; electromagnetic waves for reading the scriptures. Consequently waves need a space for their propagation. On the other side, any language needs a diffusion space between the interlocutors. The three-phase structures in the fragmentation of our social proximity is indicated by the personal pronouns which structure our conjugations. Verbs are the kinematic components of any sentence, they bring movements, modifications as well as descriptions of states and situations. Therefore we draw a functional analogy between verbs and waves. It is the crucial point of this report. In relation to their significations, a verb partition is performed in a hexagonal configuration which supports on the first side 3 active verbs: motor, social, anticipative verbs and on the second side 3 statics: state, reactive, metrological verbs. The tense range locates any sentence along the time axis. Consequently these ones can follow variation sequences and introduce the kinematic behaviour. For their representing topology it is requested to use a multidimensional complex space whose real axes support the objective tenses of simple description and whose imaginary axes support the tenses loaded with subject intentions. The future tenses necessary bring anticipative views.

Because of the correspondence of non-deterministic and deterministic FA to first and third person description, we can say that the model's dynamics is dialogue with oneself in second person. It gives rise to self-organizing behavior that is intermittent and critical. It is argued that the model is a scientific realization of deconstruction by Jacques Derrida.

Rough set driven lattice is a suitable tool for analyzing subjective phenomenon such as reading because 1) it produces Boolean as well as non-Boolean lattices that reflect the input information, and 2) this method requires two interpretations of a target, such as subject and attribute, which a sentence provides. By using this method, we can compare how a logical structure resulting from reading with anticipation is different from the information revealed by the actual text. The difference is quantified by complement properties of a lattice, through complementarity and non-distributivity.

It is a logic sequel of our article "Language and Geometry". Because the verb is the main component of its sentence, it is logic to present a sentence classification very narrowly related to the verb classification, already done in the previous paper "Language and Geometry". Besides a sentence is the shortest complete unit of language, totally structured. It acts as a semantic synergy for its components. Like vectors, the sentences have a few components which introduce the dimensions of their associated spaces. Sentence performs an idea flow what is a "Z" operator and achieves a wave modulation because it inserts idea into a mute wave which is the carrier. Conversations are dynamic nets of crossed sentences between a few interlocutors to enrich topics meanings. There is analogy between the mind analysis of a text and the tensor formation, what highlights the understanding of text structure. Sentence associated with a describing picture acquires a universal understanding because a picture plays as obvious ideogram or pictogram. This transfer is automatically performed by the mind.
