CONSTRUCTION METHOD OF SUBJECTIVE MODEL EXPRESSING COLOR IMPRESSIONS

International Journal on Artificial Intelligence Tools 2000年第4期9卷 551-568页

作者： MAKOTO KAWAMURA TAKEHISA ONISAWA Doctoral Program in Engineering University of Tsukuba Japan Institute of Engineering Mechanics & Systems University of Tsukuba Japan

This paper proposes a method to construct a subjective model expressing color impressions, which is expressed by fuzzy rules. Hue and tone are dealt with in the premise part of fuzzy rules and the degree of color impressions is expressed in the consequent part. Color impressions are the basic concept known as psychological effects of colors. In this paper two pieces of subjective information are considered in order to construct the subjective model. One is the information of the absolute relationship between a color and the subjective degree of its impressions. And the other is the one about the relative relationship between colors on a subjective measure in terms of color impressions. Two kinds of questionnaires, called the absolute and the comparative judgments, are performed to get the subjective information. Additionally, this paper proposes improves the method so that is more applicable to the practical use. A validity of the proposed methods are examined by evaluation experiments.

This paper proposes a method to estimate the posture of an athlete moving on a vast field in a sporting event using a pan-tilt-zoom camera. In order to estimate the posture of an athlete on a sports field from a dynamic video sequence, our method extracts image features to search correspondence points among successive frames and computes the homography transformation matrix that compensates for changes the camera parameters (e.g., angle of view and posture). The effectiveness of this method is qualitatively verified using MLB TV broadcast video. The accuracy and error factors are also quantitatively verified by CG simulation.

This paper discusses a problem concerning intertemporal decision-making under uncertainty when its subject has psychological biases. Here, we consider an investment company as a decision maker that invests money from investors in a financial asset and pays some dividend every period depending on the performance of the investment. On the other hand, we assume investors have such psychological biases as inconsistent time preference and loss aversion. Through numerical experiments we show that the optimal dividend distribution under inconsistent time preference and loss aversion is quite different from the distribution without these psychological factors, and that combinations of the two factors produce various patterns of dividend distribution. © 2009 Elsevier Inc.

A humanoid control method based on human knack for human care service was discussed. It was found that the humanoid model 'HRP1S' and the human model which possessed human parameters and was not able to rise by itself were used in simulation. The analysis showed that the human care by humanoid was realized and the effectiveness of the humanoid control method was verified.

＜正＞Introduction Constant-amplitude fatigue strength for the cross-ply fiber-metal laminate GLARE-3 has been studied with a particular emphasis on an elucidation of the directional characteristic. Tension-tension fatigue tests are performed at room temperature on five kinds of plain coupon specimen with a different off-axis angle. The directional characteristic of tile fatigue strength of GLARE-3 is elucidated on the basis of the off-axis S-N relationships. The off-axis S-N relationships of GLARE-3 are compared with those of unidirectional GLARE-2 [1]to

The global trend in broadband internet services reveals an increased focus on reliability, customer service, and integrating new technologies like IoT, 5G, or FMC. Customer service is primarily determined by network quality and reliability, price, and the quality of customer support provided by ISPs. Meanwhile, existing network quality measurement methods often involve numerous parameters, ranging from download speed and server response time to video streaming quality, each providing a separate insight into aspects of user experience. Therefore, the importance of the composite index method is becoming increasingly relevant. This method allows the integration of these various parameters into a single, easily understandable integrated index, simplifying complex data analysis into a more concise and interpretable form. As a result of this approach, internet service providers can more effectively monitor and enhance the customer experience and the overall quality of their services for various purposes with a single composite parameter value, providing reassurance and confidence in their operations. © 2024 IEEE.

For the person having functional disorder in their legs, we have developed Hybrid Assistive Leg(HAL). The purpose of this study is to propose the method to control HAL. In this method, according to human walking, the walking task is divided into phases. Keeping COG be controlled through all phases by manipulating ZMP, it would be possible to generate the stable motions without falling down which have several speeds and step lengths. Using computer simulation, we would confirm the effectiveness of this method and the ability for applying this method to the rehabilitation program for handicapped people. © Springer-Verlag Berlin Heidelberg 2002.

We have developed the power assistive suit, HAL (Hybrid Assistive Leg) which provide the self-walking aid for gait disorder persons or aged persons. In this paper, We introduce HAL-3 system, improving HAL-1,2 systems which had developed previously. EMG signal was used as the input information of power assist controller. We propose a calibration method to identify parameters which relates the EMG to joint torque by using HAL-3. We could obtain suitable torque estimated by EMG and realize an apparatus that enables power to be used for walking and standing up according to the intention of the operator. © Springer-Verlag Berlin Heidelberg 2002.

As online social media content continues to grow, so does the spread of hate speech. Hate speech has devastating consequences unless it is detected and monitored early. Recently, deep neural network-based hate speech detection models, particularly conventional single-channel Convolutional Neural Network (CNN), have achieved remarkable performance. However, the effectiveness of the models depends on the type of language they are trained on and the training data size. We argue that the effectiveness of the models could further be enhanced if we use multi-channel CNN models even for under-resourced languages that have limited training data size. This is because the single-channel CNN might fail to consider the potential effect of multiple channels to generate better features, which is not well investigated for hate speech detection. Therefore, in this work, we explore the use of multi-channel CNN to extract better features from different channels in an end-to-end manner on top of a word2vec embedding layer. Tested on a new small-scale Amharic hate speech dataset containing 2000 annotated social media comments, the experimental results show that the proposed multi-channel CNN model outperforms the single-channel CNN models but underperform from the baseline Support Vector Machine (SVM) with an average F-score of 81.3%, 78.2%, and 92.5% respectively. The finding of the study implies that the proposed MC-CNN model can be used as an alternative solution for hate speech detection using a deep learning approach when dataset scarcity is an issue. © 2022, ICST Institute for Computer Sciences, Social Informatics and Telecommunications engineering.
