Fuzzy rule-based classification system (FRBCS) is a popular machine learning technique for classification purposes. One of the major issues when applying it on imbalanced data sets is its biased to the majority class, such that, it performs poorly in respect to the minority class. However many cases the minority classes are more important than the majority ones. In this paper, we have extended ...

In recent years, researches on reinforcement learning (RL) have focused on bridging the gap between adaptive optimal control and bio-inspired learning techniques. Neural network reinforcement learning (NNRL) is among the most popular algorithms in the RL framework. The advantage of using neural networks enables the RL to search for optimal policies more efficiently in several real-life applicat...

The success of the World Wide Web and the Internet is causing great demand of bandwidth, increasing the latency and overloading popular servers. We propose an approach to treat very popular and frequently changed web documents using a continuously reliable multicast transmission. The beneets are very eecient use of the network resources, a reduction on the server's load, lower response times an...

We present a set of experiments involving sentence classification, addressing issues of representation and feature selection, and we compare our findings with similar results from work on the more general text classification task. The domain of our investigation is an email-based help-desk corpus. Our investigations compare the use of various popular classification algorithms with various popul...

research on popular music in iran has a short history. perhaps the article “sociology of the music of the masses in iran”, published in 1980, can be considered as the first methodological and systematic study on the popular music in iran.  in that article, the researcher, using marxist and neo-marxist approaches to study popular music, provides a general view on the music of the masses of the p...

Parametric surfaces are a powerful and popular modeling tool in computer graphics and computer aided design, while ray tracing is a versatile and very popular rendering technique. As a result, there is a strong incentive in developing fast, accurate, and reliable algorithms for solving the ray-patch-intersection problem. In this paper, we discuss and compare three recent geometric algorithms fo...
