    The techniques of artificial intelligence (AI) have been rapidly developing in video games. One of the main aims of AI implementation is to win against the human players. This is already achieved in some games, such as chess and shogi. Nowadays, the interest is moved to enhance the enjoyment of the players. Many researches are devoted to develop a human-like AI player to entertain human player. In this paper, we focused on a video game named PuyoPuyo. PuyoPuyo is one of the tile-matchins puzzle game controlling two pair of falling blocks. Random distribution of the blocks makes it difficult to set them into the ideal pattern. Skilled player seems to have some ideal pattern template models in their mind. This paper tried to derive these templates from the placements of blocks stacked by the skilled human player. Using these templates, it is partially capable of reconstruction the player's placements.

    Memory on human conduct intellectual creative activity is important. However, interaction with advanced information media is complicated, in a memory by using the complex interactions that an adverse effect is a problem. There are two types of short-term memory and long-term memory in the storage, there is a need to examine the issue from both sides. As a matter of short-term memory, even though the capacity of short-term memory is limited, forgetting of ideas it occurs and will use the capacity of short-term memory in the interaction. As a matter of long-term memory, due to the lack of meta memory of storage that rely on external storage devices, dead storage of memory occurs it can not access the storage. In this study, we pointed out the problems with the interaction of the information media, we propose solutions.

    Research on physical human-robot interaction hasbeen attracting attention recently, focusing on robot embodiment. The work reported here proposes Active Touch Communication Robot(AcToR), a robot that is modeled on the hearing dog. A hearing dog is a type of dog assist people who are deaf or hard of hearing by alerting their handler to important sounds. AcToR uses the sense of touch to notify a human of the intention to transfer information. For example, when AcToR detects that a cell phone that is in another location has received a call, AcToR moves to the user's location and makes contact with the user's body to notify the user of the incoming call. The AcToR robot is based on the Roomba and uses the Roomba's bumper and contact sensors to detect contact. This paper reports the results of psychological experiments using the AcToR robot that indicate the feasibility of using touch to transfer information from a robot to a person.

    In our laboratory, the Interactive Chaotic Amusement System (ICAS) using network of chaotic elements have been already developed. We have also studied the calculation method of relaxation degree from the frequency power content ratio and the evaluation of human impression for the relaxation effect of generated sounds. In this research, we try to construct the system to judge the degree of relaxation based on the heart rate variability and to adjust the automatic operation to obtain the relaxation effect by presenting the sound to the user. In this paper, as an advance research on the construction of this system, we analyzed various features of the heartbeat (electrocardiogram) measured in a different state and found an index that judges the relaxation degree by using fuzzy inference. And we performed the experiment to generate a relaxation sound so that the subject might be felt relaxation adopting interactive sound generation system ICAS.

    Since we can use calligraphy characters fonts on a computer, it is easy for anyone to write calligraphy characters without a brush. But it is impossible to express features of calligraphy characters particularly such as scratched look or blurred look because one calligraphy characters font has one shape of calligraphy characters. A prior research solved this problem and made calligraphy characters fonts which is scratched or blurred, but the system another problem. We can't adjust scratched or blurred look of the fonts by the system. Then, in my research, we make a system which we can use easily by innovating onomatopoeia.

    In recent years, expression education that improves imagination and communication skills of learners has been attracting attention. Current education is carried out in a one-to-many situation. Therefore it is not clear whether each learner is able to achieve his/her objective in the education particularly for expression education, because it requires class situation that a teacher has one-on-one communication with a learner. In this paper, we propose a robot to support the expression education under one-to-one situation. We conducted an experiment to verify the effect of the robot. The result showed that the robot has same effect as when performing the expression education with a human teacher.

    Clustering gene expression data has been done by many researchers. They are using traditional methods of agglomerative hierarchical clustering, which fail to use domain knowledge obtained from vast gene studies. An example of such domain knowledge is gene ontology terms for messenger RNA. We propose two methods of clustering gene expression data and different experiments using gene ontology terms. One is traditional agglomerative hierarchical clustering using similarities based on gene ontology terms. Another is algorithms using the modularity index applied to networks including gene ontology terms. Clustering results of real large-scale experiments are shown.

    Recently, in assessing harmful chemicals, low cost cell experiment has attracted a lot of attention as an alternative to animal experiment.Also in acquisition of gene expression data, it is able to acquire the large data more accurately since the next-generation sequencer is implemented. However, methods for analyzing gene expression data acquired by next-generation sequencer from cell experiment have not been established yet. In this study, we propose one of such method: a method to extract RNAs of characterizing a correlation of gene expression data. Specifically, Optimal problems for the correlation coefficients are given and the optimal solutions are acquired by the meta-heuristics. Information between gene expression data is summarized by the proposal method. The features of sets of RNAs are discussed and the effectiveness of the proposal method is evaluated through data experiments.

    Discrimination methods have been proposed by developing a discriminator used with data contains discrimination information. However, when the observed data is multivariate data the discrimination becomes more difficult. In order to solve this problem, a variable selection is important to improve the correct identification rate. In this paper, a new variable selection method is proposed through the principal components by using the relationship between discrimination information and principal components. Several numerical examples show a better performance of the proposed method.

    k-means clustering (KM) algorithm, also called hard c-means clustering (HCM) algorithm, is a very powerful clustering algorithm, but it has a serious problem of strong initial value dependence. To decrease the dependence, Arthur and Vassilvitskii proposed an algorithm of k-means++ clustering (KM++) algorithm on 2007. By the way, there are many case that each object is allocated on an unit sphere, e.g. text clustering. Honik, Kober, and Buchta proposed spherical k-means clustering (SKM) algorithm to classify such objects on 2012. However, the algorithm also has the same problem of initial value dependence as KM. Therefore, this report discuss the following points: (1) the dissimilarity of SKM is extended to satisfy the triangle inequality, and (2) spherical k-means++ clustering (SKM++) algorithm which works well for the problem is proposed. The report shows that the effectiveness of SKM+ is theoretically guaranteed.

    Clustering is a technique of unsupervised classification. The methods are classified into two types, one is hierarchical and the other is non-hierarchical. Fuzzy Non-metric Model (FNM) is a method of non-hierarchical clustering. FNM is very useful because Euclidean spaceis not required on data space and only similarity or dissimilarity between data is needed. However FNM cannot handle uncertain data, e.g. incomplete data, or data which have errors. In order to handle such data, concept of data with tolerance has been proposed. The methods using the concept can handle the uncertain data in the framework of optimization, e.g. Fuzzy $c$-means for data with Tolerance (FCM-T). In this report, first we will propose new clustering algorithm to apply the concept of tolerance to FNM. Second, we will show that the proposed algorithm handle incomplete data. Third, we will verify the effectiveness of the proposed algorithm in comparison with other ones for incomplete data through some numerical examples.

    Although semi-supervised clustering is a promising approach for improving partition quality in large-scale data analysis, it is often difficult to utilize an enough amount of supervised objects. A virtual sample approach is a practical technique for improving classification quality in semi-supervised learning, in which additional virtual samples are generated by combining several supervised objects. In this research, the virtual sample approach is adopted in semi-supervised fuzzy co-clustering and its characteristics are demonstrated through several numerical experiments.

    A prediction method of game results using kick information is studied in this paper. Although it is not possible to exactly know a strategy that an opponent team is taking, that strategy is well represented by how the players in the team kick during games. Extracted kicks such as passes and dribbles form a kickdistribution, which hopefully represent the strategy. A series of computational experiments are conducted in order to examine the performance of the proposed method.

    How to allocate goods in shop shelves makes great influence to sales amount. Searching best fit allocation of goods to shelves is a kind of combinatorial problem. This becomes a problem of integer programming and utilizing genetic algorithm may be an effective method. Reviewing past researches, there are few researches made on this. Formerly, we have presented a papers concerning optimization in allocating goods to shop shelves utilizing genetic algorithm. In those papers, the problem that goods were not allowed to allocate in multiple shelves and the problem that goods were allowed to allocate in multiple shelves were pursued. In this paper, we examine the problem that allows goods to be allocated in multiple shelves and introduce the concept of sales profits and sales probabilities. Optimization in allocating goods to shop shelves is investigated. Expansion of shelf position is executed. Utilizing genetic algorithm, optimum solution is pursued and verified by a numerical example. Various patterns of problems must be examined hereafter.

    In industry, making a correct forecasting is inevitable. If the correct forecasting is not executed, there arise a lot of stocks and/or it also causes lack of goods. Time series analysis, neural networks and other methods are applied to this problem. There are some related researches made on this. However, it can be said that an application to sales forecasting is rather a few s a whole, In this paper, neural network is applied and Multilayer perceptron Algorithm is newly developed. The method is applied to the food production data of prepared frozen foods. When there is a big change of the data, the neural networks cannot learn the past data properly, therefore we have devised a new method to cope with this. Repeating the data into plural section, smooth change is established and we could make a neural network learn more smoothly.

    In industries, how to improve forecasting accuracy such as sales, shipping is an important issue. There are many researches made on this. In this paper, a hybrid method is introduced and plural methods are compared. Focusing that the equation of exponential smoothing method(ESM) is equivalent to (1,1) order ARMA model equation, a new method of estimation of smoothing constant in exponential smoothing method is proposed before by us which satisfies minimum variance of forecasting error. Generally, smoothing constant is selected arbitrarily. But in this paper, we utilize above stated theoretical solution. Firstly, we make estimation of ARMA model parameter and then estimate smoothing constants. Thus theoretical solution is derived in a simple way and it may be utilized in various fields. Combining the trend removing method with this method, we aim to improve forecasting accuracy. Furthermore, "a day of the week index", is newly introduced to the daily shipping data of the sanitary materials and we obtained good result.

    In Interval AHP, a comparison is considered to consist of the real values in the corresponding interval weights. The widths of the interval weights are minimized so as to be close to the given comparisons as much as possible. In the same concept of Interval AHP, this study proposes the model to obtain fuzzy weights as the extension of the interval weights. In order to obtain fuzzy weights, Interval AHP is modified by focusing on the lower bounds of the interval weights from the viewpoint of belief function in evidence theory. As the given comparisons are more consistent, it means that they are based on the higher-level sets of fuzzy weights, which are denoted as interval weights.

    From the viewpoint that the vagueness of decision maker's evaluation causes the inconsistency of a pairwise comparison matrix, Interval AHP estimating interval priorities has been proposed. In this paper, we demonstrate the insufficiency of the conventional interval priority estimation method and propose several modified estimation methods which reflect more vagueness of decision maker's evaluation. In those proposed methods, interval priorities are estimated easily by solving a linear programming problem. Numerical experiments are conducted to compare estimation methods from the point of view of the accuracy in estimating interval priorities and dominance relations between alternatives. Through the experiments, the advantages of modified estimations over the conventional one are demonstrated. Furthermore, we investigate the best estimation method among them.
