Accurate estimation of software development effort is essential for effective management and control projects. Many methods have been proposed in the literature including computational intelligence models. However, none existing models proved to be suitable under all circumstances; that is, their performance varies from one dataset another. The goal an ensemble model manage each its individual models’ strengths weaknesses automatically, leading best possible decision being taken overall. In...

People depend on popular search engines, like Google and Yahoo, to retrieve the desired information from Web. Searching for right food, eat, is an example of frequent queries Web where people do not find relevant easily. One reason this un-satisfaction fact that many have personal preferences each one likes dislikes certain food. Also, some specific health conditions restrict their food choices encourage them take other In addition, cultures, live in, influence varieties. Therefore, it will...

This paper presents recently introduced learning algorithm called extreme machine (ELM) for single-hidden layer feed-forward neural-networks (SLFNs) which randomly chooses hidden nodes and analytically determines the output weights of SLFNs. The ELM avoids problems like local minima, improper rate over fitting commonly faced by iterative methods completes training very fast. We have evaluated multicategory classification performance on five different data sets related to bioinformatics...

The implementation of CPU-Scheduling algorithms such as Shortest-Job-First (SJF) and Shortest Remaining Time First (SRTF) is relying on knowing the length CPU-bursts for processes in ready queue. There are several methods to predict CPU-bursts, exponential averaging method, however these may not give an accurate or reliable predicted values. In this paper, we will propose a Machine Learning (ML) based approach estimate processes. proposed aims select most significant attributes process using...
