Abstract   Many parameter-tuning algorithms have been proposed for training Fuzzy Wavelet Neural Networks (FWNNs). Absence of appropriate structure, convergence to local optima and low speed in learning algorithms are deficiencies of FWNNs in previous studies. In this paper, a Memetic Algorithm (MA) is introduced to train FWNN for addressing aforementioned learning lacks. Differential Evolution...

The Internet is changing the transaction pattern of B2B markets. One of the major concerns of IT knowledge-based companies is how to take advantage of B2B online markets. These companies believe that the only possible strategy for entering these markets is to launch independent websites, and they are usually reluctant to enter these markets due to the requirements such as financial resources an...

Risk is anything that threatens the successful achievement of a project’s goals. The fundamental principle of risk-based testing is to do more thorough testing to those parts of the software system that present the highest risk. In this fast abstract, we introduce risk-based testing and discuss applying risk analysis to select test cases for regression testing which is essential to ensure softw...

An alternative to the typical technique of selecting training examples independently from a fixed distribution is fonnulated and analyzed, in which the current example is presented repeatedly until the error for that item is reduced to some criterion value, ~; then, another item is randomly selected. The convergence time can be dramatically increased or decreased by this heuristic, depending on...

With the rapid increase of data volume, more and more applications have to be implemented in a distributed environment. In order to obtain high performance, we need to carefully divide the whole dataset into multiple partitions and put them into distributed data nodes. During this process, the selection of partition key would greatly affect the overall performance. Nevertheless, there are few w...

Marketing establishes a communication network between producers and consumers. Nowadays, marketing approach is customer-focused and products are directly oriented to meet customer needs. Marketing, which is a long process, needs organization and management. Therefore strategic marketing planning becomes more and more important in today’s competitive conditions. Main focus of this paper is to ev...

Software is unequivocally the foremost and indispensable entity in this technologically driven world. Therefore quality assurance, and in particular, software testing is a crucial step in the software development cycle. This paper presents an effective test selection strategy that uses a Spectrum of Complexity Metrics (SCM). Our aim in this paper is to increase the efficiency of the testing pro...

Brain regions involved in transforming sensory signals into movement commands are the likely sites where decisions are formed. Once formed, a decision must be read out from the activity of populations of neurons to produce a choice of action. How this occurs remains unresolved. We recorded from four superior colliculus neurons simultaneously while monkeys performed a target selection task. We i...

In this paper, we explore the use of genetic algorithms (GAs) to construct a system called GABIL that continually learns and refines concept classification rules from its interaction with the environment. The performance of this system is compared with that of two other concept learners (NEWGEM and C4.5) on a suite of target concepts. From this comparison, we identify strategies responsible for...
