    Human bodily motions are effectively used to communicate, and the ability to read the intentions behind those is essentially important for the machine system to collaborate with the human. If we use behaviors as medium of communication with the machine, the machine system should be able to construct meanings from them. In this paper, semiosis and related topics of symbol grounding are reviewed, an... View full abstract»

    One of the main goals of artificial intelligence is to realize an intelligent agent that behaves autonomously by its sense of values. Reinforcement learning (RL) is the major learning mechanism for the agent to adapt itself to various situations of an unknown environment flexibly. The merit of RL is that only giving the agent a goal state as setting a reward, a set of optimal behavior sequences to... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (512 KB)

    In this paper, we examine arrangements of social agents that have social value orientations (SVOs). SVOs differ in terms of two value systems: (1) concern. with the well being of others and (2) concern with well being of self. Agents are allocated in line land space and they play randomly generated N-persons games. Based on the SVOs, the agents intend to get high satisfactions. In these random gam... View full abstract»

    A theory representing the dynamics of infinite population genetic algorithms (GAs) is given by using Eigen's (1971) evolution model. The effect of crossover, which was neglected in Eigen's original theory of molecular evolution, is included to study the evolution of infinite population GAs. In this paper, we present a theory of GA dynamics, in which we give a coupled form of discrete time equation... View full abstract»

    Weighted OWA (ordered weighted aggregation) operators were introduced as a generalization of the weighted mean (WM) and the OWA operators, so that the advantages of both could be used in a single data fusion function. In this work, we study the determination of their parameters when a set of examples is at our disposal. The approach presented in this paper is of interest in data mining when a cert...

    Control of induction machines without mechanical sensors has gained more and more interest in the past years. Different methods for sensorless control have been proposed in literature recently. To guarantee a stable operation in the whole fundamental frequency range including zero fundamental stator frequency, it is not enough to consider only the fundamental wave behaviour of the machine. All the... View full abstract»

    This paper presents a novel design method for discrete systems. The model is based on a concept of poles over an extension field of GF(2). Then the nonlinearity of the discrete systems is considered by the exact linearization method. The proposed approach realizes a cost reduction in software development of discrete systems View full abstract»

    We combine local search algorithms with genetic algorithms. In this context local search can be thought of as learning over an individual's lifetime. We investigate two different ways of incorporating learning into the hybrid algorithm: Lamarckian evolution and the Baldwin effect. For each model we systematically vary the proportion of the population undergoing learning. We found that the quality ... View full abstract»

    This paper considers cyclic job-shop-scheduling problems (CJSSP) extended from the job-shop-scheduling problem (JSSP). Our approach, called "evolutionary Petri net", solves the problem approximately by evolving the net structure of Petri nets. We propose an effective crossover which employs structural analysis of the Petri net model. The proposed crossover can accelerate the evolution View full abstract»

    Evolutionary algorithms (EAs) are randomized search strategies that have turned out to be efficient for somewhat different optimization problems. In order to understand the behavior of EAs, one is also interested in examples where EAs need exponential time to find an optimal solution. Until now only artificial examples of this kind were known. An example with a clear and simple structure is presen... View full abstract»

    In this paper, we extend genetic algorithms with double strings based on reference solution updating proposed by Sakawa et al. (1997, 1999) for 0-1 programming problems into integer programming problems. In addition, considering the property that an optimal solution to an integer programming problem is close to an optimal solution to the corresponding linear programming relaxation problem, we atte...

    A time delay control can be applied to Chua's circuit by adding a small-amplitude time-delay feedback voltage. The state of the circuit can easily be governed by the feedback from order to chaos. The chaotic dynamics of this newly derived circuit is analyzed theoretically, and verified by computer simulation as well as by electronic circuitry View full abstract»

    As the amount of information in the world steadily increases, there is a growing demand for tools for analyzing this information. In this paper, we investigate the problem of data mining, i.e. constructing decision rules from a set of primitive input data. The main contention is that there is a need to be able to generate decision rules and to reason in presence of inconsistencies. Propositional d... View full abstract»

    In eddy current testing of steam generator tubes, signals are sometimes rendered noisy by the presence of other structures, such as support/tube plates outside of test materials, as well as the lift-off noise due to the expansion zone of the tube. This paper describes a new method for the crack reconstruction from these noisy signals, developed with a fast signal prediction and the steepest descen... View full abstract»

    Many applications of reinforcement learning (RL) and evolutionary computation (EC) are addressing the same problem, namely, to maximize some agent's fitness function in a potentially unknown environment. The most challenging open issues in such applications include partial observability of the agent's environment, hierarchical and other types of abstract credit assignment, and the learning of cred...

    A pyramid model is proposed for blind deconvolution problem of image restoration based on simulated annealing (or other heuristic method). The proposed approach is like a pyramid. The authors start the restoration from a low resolution level. As the image with the low resolution is restored, the restored image (low resolution) is expanded to an image with higher resolution, which is used as an ini... View full abstract»

    Recent reports show that chaotic simulated annealing (CSA) can be successfully used to find the global optimum or near optimum with a set of parameters carefully chosen. However, CSA still user a penalty term to enforce solution validity us in the Hopfeld-Tank approach. This penalty method exhibits a conflict between solution quality and solution validity in the penalty approach. In addition, the ... View full abstract»

    Many applications involving induction motors that are controlled using variable frequency drives (VFDs) require the ability to stop quickly. These applications include emergency stops, quick stopping of fans, centrifuges, presses, etc. The technique that is widely accepted in the industry for achieving fast stopping makes use of brake resistors in series with a power semiconductor switch.

    This paper deals with a guidance performance of a Maglev vehicle, which is guided originally by the interactions between the onboard superconducting magnets and the induced currents of short-circuited coils on the ground. Although the original electrodynamic guidance system may have a sufficient spring modulus, the damping factor is not enough so that it may not provide a good ride comfort for pas...
