Fuzzy Time series (FTS) has been widely applied to handle non-linear problems, such as enrollment estimation, weather prediction and stock index forecasting. FTS predicted values on the basis of an equal interval, which is determined the early stages of forecasting in the model. In this paper, we employed Genetic Algorithms (GA) to optimize the interval at first. Based on this, then Rough Set (RS)...
Fuzzy time-series (FTS) has been applied to handle non-linear problems, such as enrollment, weather and stock index forecasting. In the forecasting processes, fuzzy logical relation (FLR) plays a pivotal role in forecasting accuracy. Usually FTS uses an equal interval to obtain forecasting values. But in this paper, we use genetic algorithm (GA) to optimize the interval at first. Based on this, then...
Feature selection is to select an informative subset from original feature set aiming at reducing the dimension of the feature space and enhancing the performance of the classifier. It is a crucial problem of pattern recognition and has attracted much attention in recent years. In this paper, we have proposed a multi-population univariate marginal distribution algorithm using random population to...
A type of UWB body-of-revolution monopole antenna is presented with an outer surface which is characterized by a sequence of 2-D line segments defined by their length and angle. Using the genetic algorithm, a 24″ wide and 6″ tall metallic antenna structure is optimized to deliver a highly stable radiation pattern particularly at high frequency end (up to 2.5 GHz). Moreover, a different configuration...
Collision detection is necessary in order to resolve interaction between teeth in dental arrangement. Dental arrangement is a part of the invisible correction system which is a computer aided system helping dentist to find a way to correct teeth in disorder. This paper discusses the importance of collision detection; a method has been developed for it, based on a physically-based modeling of triangle...

Many existing software reliability models are based on some subjective assumptions those could be easily impractical in reality. Genetic Programming(GP for short) does not need some subjective assumption due to the basic characteristic of the data. Also, this method doesn't require to understand the inherent processes for failures, but to create models based on the given data for a "true"...
Due to the combinatorial nature of product configuration problem and the characteristics of multi-objective and multi-constrain, an effective product configuration model is established to transform the complicated problem into the path optimization problem. A hybrid intelligent algorithm is adopted, which united the genetic principle, the ant colony mechanism and the simulation anneal theory into...
