Brain-computer interface (BCI) and brain-machine interface (BMI) technologies have recently entered the research limelight. In many such systems, external computers and machines are controlled by brain activity signals measured using near-infrared spectroscopy (NIRS) or electroencephalograph (EEG) devices. In this paper, we propose a novel boosting algorithm for BCI using a probabilistic data interpolation scheme. In our model, interpolated data is generated around classification errors using a probability distribution function, as opposed to conventional AdaBoost which increases weights corresponding to the misclassified examples. By using the interpolated data, the discriminated boundary is shown to control the external machine effectively. We verify our boosting method with an experiment in which NIRS data is obtained from subjects performing a basic arithmetic task, and discuss the results.

The new classification method was proposed which visualizes a multidimensional data set. A dendrogram was created by the distance calculation among the labels. Based on this dendrogram, the colored classification of the cluster group was carried out on the spherical surface based on the label data. This method can be applied to a variety of data. Here, the following problems were analyzed which are the chain-link problem that the representation is generally made difficult, and a problem of the separation of the layered random number planes. In each problem, the representation position of each representative point was examined.

It is clear that each position and the aptitude of a role have effected a team state in organized sports. Many researches are made from standpoints, such as the physical features and mental features. However, the research that shows individual role and relationship within a team in the game in consideration of both sides is very rare. And, the relevance about the amount of physical features and amount of mental features is not yet clear. So, in this research, we aim to develop the clustering method in considering physical and mental features for judging a individual role and adaptation in the game. In this paper, we report the concept of the algorithm and result of the data analysis.

The acceptance standard of the MS which is recommended at present is hereinafter. It is judged as a MS when the abdominal circumscript exceeds a standard in the first stage and then, 2 items exceed a standard value from the following 5 items of the fasting blood sugar level, the systolic blood pressure, the diastolic blood pressure, the acylglycerol, and HDL cholesterol. In the method, every single item is compared with the standard value. It is then judged to be extraordinary even if when exceeding a little. Also, in the non- pycnic type, it isn't evaluating accurately a MS modality except the abdominal circumscript. We establish a non-ill area outside the standard value. The general MS distinction method was contrived which depends on SOM and the problem of the existing method was verified by this SOM method. by this SOM method.

For learning in continuous value space, reinforcement learning used neural networks is investigated actively. But network configurations of conventional neural network models are fixed, and it is almost impossible to predict and determine proper configuration for best learning performance, because, in reinforcement learning, quantities of training data to obtain enough learning performance are unknown. In this study, we propose a reinforcement learning introduced neuron addition mechanism which is based on RCE model, and evaluate its basical performance.

Competitive facility location problem (CFLP) is one of optimal location problems for commercial facilities, e.g. shops and stores, and the objective of a decision maker for the CFLP is to maximize the obtaining demands from customers of facilities. This study focuses on a CFLP with uncertain and vagueness demands. By representing the demand for facilities with fuzzy random numbers, a CFLP can be formulated as a fuzzy random programming problem. For solving the formulated CFLP, it is reformulated to the problem as the problem to find their optimal solutions maximizing a degree of necessity under some chance constraint. After showing that one of their optimal solutions can be found by solving 0-1 programming problems, their solution method is proposed by improving the tabu search algorithm with strategic oscillation. The efficiency of the proposed method is shown by the results of applying it to numerical examples of CFLP.

In general, it is not easy to put Reinforcement Learning into practical use. Our approach mainly deals with the problem of designing state and action spaces. Recently, we have proposed a co-construction method of state and action spaces. In this paper, we propose a detection method of environmental changes and a co-construction method by partially enlarging of the calibration of state and action spaces to adapt dynamic environment. In addition, the validity of the proposed method is confirmed through computational experiments using a so-called "path plannning problem" under dynamic environment.

We apply shift type transformation for fuzzy subjects. We find the inference solutions depend on high level gene number h. The h gets bigger, the tumor of the solutions becomes larger. We use both straight line subjects and S-function subjects. We find no difference between the solutions in straight line subjects and those in S-function subjects.

Ariticulated steering is a system which has front and rear body, connected them at center pin, and turns by the difference between angle of their body. Compared with front wheel steering and rear wheel steering, the turning radius of this type vehicle is small, and both front and rear wheel follow the same path. Such features enable this vehicle is suitable for working in construction. But this steering system is difficult to control the position and angle of the vehicle, because when we change the steering angle, the position and angle of the vehicle also changes. In this study, we propose automated driving system that consider the characteristics of articulated steering type vehicle.

We propose a classification method for high dimension low sample-size data. High dimension low sample-size data (HDLSS data) is data in which the number of dimensions is much larger than the number of objects. Such data is commonly found amongst real world data such as microarray data or image data. However, it is well known that we tend to obtain poor classification results when applying conventional clustering methods which are based on distance for this type of data. In this paper, we propose an adaptable feature selection method and a related clustering method along with the results of several numerical examples to show the improved performance.

The specification of blood vessel region in the retinal fundus images is one of the important basic technologies in the development of the computer-aided diagnosis systems for funduscopy. In this report, a new blood vessel region extraction method based on the black-top-hat transformation (BTH), which is one of morphological operations, is proposed. In the proposed method, firstly, BTHs with two structuring elements having different radii are applied to the retinal fundus image in parallel. Then the binarization is achieved for the transformed images and tentative blood vessel regions are extracted by using binarized images. Consequently, the final blood regions are determined by correcting the images, which are obtained after synthesizing complementary tentative images. In this study, the experiments using some practical retinal fundus images were executed, and the effectiveness of the proposed method was verified by detection rate of the blood vessels. From the experimental results, it can be said that the proposed method is effective for the blood vessel region extraction from the retinal fundus images.

This paper presents a Takagi-Sugeno fuzzy modeling and linear matrix inequaility (LMI) based parallel distributed compensation (PDC) approach to modeling and control of an F16 aircraft nonlinear model. After presenting dynamics of an F16 nonlinear model, fuzzy model-based control results are discussed in comparison with linear control results. The fuzzy controllers designed using the LMI based PDC approach guarantee not only stability but also decay rate and constraints on control inputs (actuator saturation) and outputs. Finally, simulation results demonstrate that the fuzzy controllers can stabilize the original (not simplified) nonlinear F16 model with given initial conditions although the linear controllers cannot stabilize the systems.

There have been many studies on semi-supervised classification, but methodological aspects such as generalization capability of a particular method and relation of solutions by different methods of clustering is relatively unknown. We consider a family of method related to K-means, and show how the above problems are studied and solved. Moreover methods of on-line K-means are generalized and semi-supervision is incorporated.

This paper deals with a design of the fuzzy model following control systems with disturbances. We guarantee the boundedness of the inner states for the control systems. Numerical example shows that the output signal of the control systems asymptotically follows the reference model output signal with disturbances.

In the field of robot-assisted therapy, the impression evaluation for robot behaviors are important for enhancing the effect of treatment.This paper presents the impression evaluation for mixed walking motion of animal type quadrupedal robot "AIBO" .We verified the effects of different behaviors on human sensibility evaluation by comparing between the normal pre-installed gait and the animal-like gait generated by imitating canine walking, optimizing a leg path using a genetic algorithm and applying a zoological basis.Moreover, we analyzed the relationship between behaviors and impressions by evaluating the three mixed walking motions.

We propose Chain Form Reinforcement Learning for a reinforcement learning agent. In the real world, learning is difficult because there are an infinite number of states and actions that need a large number of stored memories and learning times. To solve a problem, estimated values are categorized as"GOOD" or "NO GOOD" in the reinforcement learning process. Additionally, the alignment sequence of estimated values is changed because they are regardedas an important sequence themselves. We conducted some simulations and observed the influence of our methods.

Reinforcement learning has important aspects for exploratory try-and-error and delayed reward. However, it needs many learning cycles and takes a long time to get a sufficient reliable learned result. In order to solve the problem, there is a transfer learning, which requires how to decide the transferring knowledge and how to transfer it. Additionally, an achieved knowledge is not always suited for the task in the real world. In this research, we proposed a communication method based on PCA and discussed these problems with several methods and simple simulation.

Army ants performs the altruism, in which an ant sacrifices its own well-being for the benefit of another ants. We developed the multi agent system of army ants. A kind of altruism is appeared in the simulation results of the system which has 2 kinds of ant agents, `Major ant' and `Minor ant'. Ants communicate with each other pheromones. The pheromones evaporate at a ratio and diffused into the space of neighbors. The other ants can recognize them as the signals from the other ants. In this paper, the distribution of diffusion is performed on a stochastic function. This paper describes the performing altruism of ant based multi agent system.
