 Second-Order Learning for Complex Forecasting Tasks: Case Study of Video-On-Demand Steven H. Kim, and Jonghyung Joo Vol. 3, No. 1, Page: 31 ~ 45 Keywords : Neural networks, case based reasoning, induction Show / Hide Abstract Abstract To date, research on data mining has focused primarily on individual techniques to su, pp.rt knowledge discovery. However, the integration of elementary learning techniques offers a promising strategy for challenging a, pp.ications such as forecasting nonlinear processes. This paper explores the utility of an integrated a, pp.oach which utilizes a second-order learning process. The a, pp.oach is compared against individual techniques relating to a neural network, case based reasoning, and induction. In the interest of concreteness, the concepts are presented through a case study involving the prediction of network traffic for video-on-demand.
 Predicting Exchange Rates with Modified Elman Network Beum-Jo Park Vol. 3, No. 1, Page: 47 ~ 68 Keywords : Predictions of Daily Exchange Rate Returns, Nonlinearity, BDS statistic, Artificial Neural Networks, Backpropagation Show / Hide Abstract Abstract This paper discusses a method of modified Elman network(1990) for nonlinear predictions and its a, pp.ication to forecasting daily exchange rate returns. The method consists of two stages that take advantages of both time domain filter and modified feedback networks. The first stage straightforwardly employs the filtering technique to remove extreme noise. In the second stage neural networks are designed to take the feedback from both hidden-layer units and the deviation of outputs from target values during learning. This combined feedback can be exploited to transfer unconsidered information on errors into the network system and, consequently, would improve predictions. The method a, pp.ars to dominate linear ARMA models and standard dynamic neural networks in one-step-ahead forecasting exchange rate returns.
 A learning algorithm of fuzzy neural networks with extended fuzzy weights Young-Su Son, Young-Nam Na, and Sang-Hyun Bae Vol. 3, No. 1, Page: 69 ~ 81 Show / Hide Abstract Abstract In this paper, first we propose an architecture of fuzzy neural networks with triangular fuzzy weights. The proposed fuzzy neural network can handle fuzzy input vectors. In both cases, outputs from the fuzzy network are fuzzy vectors. The input-output relation of each unit of the fuzzy neural network is defined by the extention principle of Zadeh. Also we define a cost function for the level sets(i. e., $\alpha$ 수식 이미지-cuts)of fuzzy outputs and fuzzy targets. Then we derive a learning algorithm from the cost function for adjusting three parameters of each triangular fuzzy weight. Finally, we illustrate our a, pp.oach by computer simulation examples.
