In this paper, we propose a new computational method for a network-growing method called greedy network-growing. We have so far introduced a network-growing algorithm called greedy network-growing based upon information theoretic competitive learning. For competitive unit outputs, we have used the inverse of the squares of Euclidean distance between input patterns and connections. The algorithm has extracted very faithful representations of input patterns. However, one problem is that learning is very slow, and sometimes ambiguous final representations are obtained. To remedy these shortcomings, we introduce a new activation function, that is, Gaussian activation functions for competitive units. By changing a parameter for the Gaussian activation functions, we can build a network that does not focus on faithful representations of input patterns, but try to extract the main characteristics of input patterns. Because this method are not concerned with detailed parts of input patterns, learning is significantly accelerated and salient features should be extracted. We applied the method to a road classification problem. Experimental results confirmed that learning was significantly accelerated and salient features could be extracted.

International conference on New Interfaces for Musical Expression, NIME 2003

In this paper, we introduce Block Jam, a Tangible User Interface that controls a dynamic polyrhythmic sequencer using 26 physical artifacts. These physical artifacts, that we call blocks, are a new type of input device for manipulating an interactive music system. The blocks’ functional and topological statuses are tightly coupled to an ad hoc sequencer, interpreting the user’s arrangement of the blocks as meaningful musical phrases and structures. We demonstrate that we have created both a tangible and visual language that enables both the novice and musically trained users by taking advantage of both their explorative and intuitive abilities. The tangible nature of the blocks and the intuitive interface promotes face-to-face collaboration and social interaction within a single system. The principle of collaboration is further extended by linking two Block Jam systems together to create a network. We discuss our project vision, design rational, related works, and the implementation of Block Jam prototypes. © 2003, Steering Committee of the International Conference on New Interfaces for Musical Expression.

Flexible self-organizing maps by information maximization

International Joint Conference on Neural Networks (IJCNN)

作者： R. Kamimura T. Takeuchi Information Science Laboratory and Future Science and Technology Joint Research Center Tokai University Hiratsuka Kanagawa Japan Human-Computer Interaction Group Institute for Human Science and Biomedical Engineering National Institute for Advanced Industrial Science and Technology Tsukuba Japan

In this paper, we propose a new information theoretic method for self-organizing maps. The method aims to control competitive processes flexibly, that is, to produce different competitive unit activations according to information content obtained in learning. Competition is realized by maximizing mutual information between input patterns and competitive units. Competitive unit outputs are computed by the inverse of distance between input patterns and competitive unit. As distance is smaller, a neuron tends to fire strongly. Thus, winning neurons represent faithfully input patterns. We applied our method to a road classification problem. Experimental results confirmed that the new method could produce more explicit self-organizing maps than conventional self-organizing methods.

Navigation Patterns and Usability of Zoomable User Interfaces with and without an Overview

引用

ACM Transactions on computer-human interaction 2002年第4期9卷 362-389页

作者： Hornbæk, Kasper Bederson, Benjamin B. Plaisant, Catherine University of Copenhagen Department of Computing Copenhagen Ø Universitetsparken 1 DK-2100 Denmark University of Maryland Department of Computer Science Human-Computer Interaction Laboratory United States

The literature on information visualization establishes the usability of interfaces with an overview of the information space, but for zoomable user interfaces, results are *** compare zoomable user interfaces with and without an overview to understand the navigation patterns and usability of these interfaces. Thirty-two subjects solved navigation and browsing tasks on two maps. We found no difference between interfaces in subjects' ability to solve tasks correctly. Eighty percent of the subjects preferred the interface with an overview, stating that it supported navigation and helped keep track of their position on the map. However, subjects were faster with the interface without an overview when using one of the two maps. We conjecture that this difference was due to the organization of that map in multiple levels, which rendered the overview unnecessary by providing richer navigation cues through semantic zooming. The combination of that map and the interface without an overview also improved subjects' recall of objects on the map. Subjects who switched between the overview and the detail windows used more time, suggesting that integration of overview and detail windows adds complexity and requires additional mental and motor effort. © 2002, ACM.

During the last years, the significant increase of mobile communications has resulted in the wide acceptance of a plethora of new services, like communication via written short messages (SMS). The limitations of the dimensions and the number of keys of the mobile phone keypad are probably the main obstacles of this service. Numerous intelligent techniques have been developed aiming at supporting users of SMS services. Special emphasis has been provided to the efficient and effective editing of words. In the presented research, we introduce a predictive algorithm that forecasts Greek letters occurrence during the process of compiling an SMS. The algorithm is based on Bayesian networks that have been trained with sufficient Greek corpus. The extracted network infers the probability of a specific letter in a word given one, two or three previous letter that have been keyed by the user with precision that reaches 95%. An important advantage, compared to other predictive algorithms is that the use of a vocabulary is not required, so the limited memory resources of mobile phones can easily accommodate the presented algorithm. The proposed method1 achieves improvement in the word editing time compared to the traditional editing method by a factor of 34.72%, as this has been proven by using Keystroke Level Modeling technique described in the paper. © Springer-Verlag Berlin Heidelberg 2002.

Greedy information acquisition in multi-layered networks

Greedy information acquisition in multi-layered networks

International Conference on Neural Information Processing

作者： R. Kamimura H. Takeuchi Information Science Laboratory and Future Science and Technology Joint Research Center Tokai University Hirakata Kanagawa Japan Human-Computer Interaction Group Institute for Human Science and Biomedical Engineering National Institute for Advanced Industrial Science and Technology Tsukuba Japan

In this paper, we extend our greedy information algorithm to multi-layered networks for improved feature detection. We have developed a new information theoretic network-growing model called greedy information acquisition. The method have shown good performance in extracting salient features in input patterns. However, because networks used in the method are single-layered ones, it has shown some difficulty in dealing with complex problems. In this context, we extend our greedy information acquisition method to multi-layered networks. By multi-layered networks, we can solve many complex problems that single-layered networks fail to do. The new algorithm was applied to two problems: the famous vertical-horizontal lines detection and a drive scene classification problem. In both cases, experimental results confirmed that our method could solve complex problems that single-layered networks fail to do. In addition, information maximization makes it possible to extract salient features in input patterns. The new algorithm can certainly contribute to the extension of neural computing.
