Two-dimentional Encoding Schema and Genetic Operators
Tzung-Pei Hong, Ming-Wen Tsai, Tung-Kuan Liu
In this paper, we propose a new genetic algorithm based on the two-dimensional encoding method. Appropriate two-dimensional crossover and mutation operations are designed based on the two-dimensional representation to generate the next generations. A two-dimensional repairing mechanism is also proposed...

Return Distribution under Behavioral Biases: A Numerical Simulation Study
Xiaoguang Yang, Fenghua Wen, Delong Huang, Qiujun Lan
Investors’ overconfidence and regret aversion lead to behavioral biases, such as over-reaction、under-reaction and disposition effect. By constructing a numerical simulation model, this paper shows that, return distributions under the behavioral biases have higher peaks and fatter tails, and they are...

Natural Scene Segmentation Based on Information Fusion and Homogeneity Property
Heng-Da Cheng, Manasi Datar, Wen Ju
This paper presents a novel approach to natural scene segmentation. It uses both color and texture features in cooperation to provide comprehensive knowledge about every pixel in the image. A novel scheme for the collection of training samples, based on homogeneity, is proposed. Natural scene segmentation...

Fuzzy Logic for Developments and Applications of Unbalance Three-Phase Fuzzy Feeder Models
Shyi-Wen Wang
Based on the fuzzy set theory, this study introduces three novel three-phase fuzzy feeder models for fast distribution system calculations. These fuzzy models are formulated using three lumped individual phase loads to represent single-phase, three-phase unbalanced, and nonuniformly distributed loads...

Image-Based Fire Detection Using Neural Networks
Wen-Bing Horng, Jian-Wen Peng
An image-based fire detection method using neural networks is proposed in this paper. First, flame color features, based on the HSI color model, are trained by a backpropagation neural network for flame recognition. Then, based on the learned flame color features, regions with fire-like colors are roughly...

A Key Renewal Scheme under the Power Consumption for Wireless Sensor Networks
Chien Lung Wang, Tzung-Pei Hong, Gwoboa Horng, Wen-Hung Wang
In this paper, we propose a distributed, reliable and low-power-consumed key-renewal scheme for wireless sensor networks. The proposed scheme is divided into parts: the server part and the sensor-node part. The server will produce an appropriate key-generation function (KGF) for key renewal on sensor...

Hybrid Neural Network Bankruptcy Prediction: An Integration of Financial Ratios, Intellectual Capital Ratios, MDA, and Neural Network Learning
Wen-Kuei Hsieh, Shang-Ming Liu, Sung-Yi Hsieh
One purpose of this paper is to propose hybrid neural network models for bankruptcy prediction. The proposed hybrid neural network models are, respecitvely, a MDA model integrated with financial ratios, a MDA model integrated with financial ratios and intellectual capital ratios, a MDA-assisted neural...
