In this work, data is obtained from two sources, the NASA Metrics Data Program, and the open source Eclipse project.Feature selection before learning is applied, and in this area a number of different feature selection methods are applied to find which work best.Given the cost and importance of removing errors improvements in fault detection and removal can be of significant benefit.
Various types of software models are there like waterfall model, V-Shaped model, spiral model, prototype model, agile model, Iterative model etc.
These models give step by step implementation of various phases of software development.
Software Quality Software Quality refers to the study of software features both external and internal taking into consideration certain attributes.
External features mean how software is performing in a real-world environment while internal features refer to the quality of code written for the software.
Some works are not in either database and no count is displayed.
Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.A significant proportion of the cost of software development is due to software testing and maintenance.This is in part the result of the inevitable imperfections due to human error, lack of quality during the design and coding of software, and the increasing need to reduce faults to improve customer satisfaction in a competitive marketplace.External quality is dependent on the internal in the sense that software works in the real-world environment with respect to the code written by the coder.Software Testing After the software product is implemented, it goes through the testing phase to find any underlying error or bug.In data modeling, initially, a conceptual data model is created which is later translated to the physical data model.UML(Unified Modeling Language)This was all about Software Engineering.Two machine learning algorithms are applied to the data - Naive Bayes and the Support Vector Machine - and predictive results are compared to those of previous efforts and found to be superior on selected data sets and comparable on others.In addition, a new classification method is proposed, Rank Sum, in which a ranking abstraction is laid over bin densities for each class, and a classification is determined based on the sum of ranks over features.A novel extension of this method is also described based on an observed polarising of points by class when rank sum is applied to training data to convert it into 2D rank sum space.SVM is applied to this transformed data to produce models the parameters of which can be set according to trade-off curves to obtain a particular performance trade-off. These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different.
