Social Network Based Recommendation System, Manish Singh Jan 2013

Social Network Based Recommendation System, Manish Singh

Computer Science

Every day we are overwhelmed with choices and options. Recommendation systems have gained popularity in providing suggestions. But every web application today has its own recommendation system. The recommendations provided by these systems are generic than user specific. Also the consumers of these systems are facing with the challenge of trusting these resources as they come from anonymous users. In this paper we propose a social networking based collaborative filtering recommendation system for movies. The prediction rating for a movie is provided based on similarity between you and your friends in the recommendation system. We have used two approaches to …

An Application Of Association Rule Mining To Unit Test Selection, Karl Nils Gunderson Jan 2013

An Application Of Association Rule Mining To Unit Test Selection, Karl Nils Gunderson

Computer Science

Appropriate selection of unit tests during the software development process is vital when many unit tests exist. The developer may be unfamiliar with some tests and non-obvious relationships between application code and test code may exist. Poor test selection may lead to defects. This is especially true when the application is large and many developers are involved. By the application of association rule mining to the unit test selection process and by comparison with extant selection techniques, we will provide a quantitative analysis of the benefits of heuristic and its limit to development where process patterns are stable.

Real Parameter Optimization Using Differential Evolution, Deepak Dawar Jan 2013

Real Parameter Optimization Using Differential Evolution, Deepak Dawar

Computer Science

Over recent years, Evolutionary Algorithms (EA) have emerged as a practical approach to solve hard optimization problems presented in real life. The inherent advantage of EA over other types of numerical optimization methods lies in the fact that they require very little or no prior knowledge of the objective function. Information like differentiability or continuity is not necessary. The inspiration to learn from evolutionary processes and emulate them on a computer comes from varied directions, the most pertinent of which is the field of optimization. This paper presents one such Evolutionary Algorithm known as Differential Evolution (DE) and tests its …

Noise Removal From Attribute-Groups For Classification, Angshu Kar Jan 2013

Noise Removal From Attribute-Groups For Classification, Angshu Kar

Computer Science

In this work, we present a novel algorithm that considers attributes from different experimental sources as separate groups for the purpose of classification. We remove noise from each of these groups, combine them, and then run the classifier on the grouped data. Examples are considered to be noise if they do not contribute to the prediction but, rather, degrade the quality of the classification result. As part of this work, we identify a measure that appropriately labels noise without knowledge of the class labels. Our method shows that the classification result is better when run on such filtered, grouped data …

Simulating Multi-Agent Decision Making For A Self Healing Smart Grid, Steve Martin Bou Ghosn Jan 2013

Simulating Multi-Agent Decision Making For A Self Healing Smart Grid, Steve Martin Bou Ghosn

Computer Science

Dynamic real-time power systems like the national power grid operate in continuously changing environments such as adverse weather conditions, power line malfunctions, device failures, etc. These disruptions can lead to different fault conditions in the power system, ranging from a local outage to a cascading failure of global proportions. It is vital to be able to guarantee that all consumers with critical loads won’t be seriously affected when these outages occur, and to also be able to detect potential faults early on, to prevent them from spreading and creating a generalized failure. In order to achieve this, the power grid …

Job Scheduling With Genetic Algorithm, Debarshi Barat Jan 2013

Job Scheduling With Genetic Algorithm, Debarshi Barat

Computer Science

In this paper, we have used a Genetic Algorithm (GA) approach for providing a solution to the Job Scheduling Problem (JSP) of placing 5000 jobs on 806 machines. The GA starts off with a randomly generated population of 100 chromosomes, each of which represents a random placement of jobs on machines. The population then goes through the process of reproduction, crossover and mutation to create a new population for the next generation until a predefined number of generations are reached. Since the performance of a GA depends on the parameters like population size, crossover rate and mutation rate, a series …

Parallelization Of Generic Pso Java Code Using Mpjexpress, Manoj Babu Madamanchi

Computer Science

Many scientific, engineering and economic problems involve the optimization of a set of parameters. The Particle Swarm Optimization (PSO) is one of the new techniques that have been empirically shown to perform well. The PSO algorithm is a population-based search algorithm based on simulating the social behavior of birds within a flock. Large-scale engineering optimization problems impose large computational demands, resulting in long solution times even on modern high-end processors. To obtain enhanced computational throughput and global search capability parallel algorithms and parallel architectures have drawn lots of attention. Parallelization of PSO has proved to enhance computational throughput and global …

Adaptive Regression Testing Strategies For Cost-Effective Regression Testing, Amanda Jo Schwartz Jan 2013

Adaptive Regression Testing Strategies For Cost-Effective Regression Testing, Amanda Jo Schwartz

Computer Science

Regression testing is an important but expensive part of the software development life-cycle. Many different techniques have been proposed for reducing the cost of regression testing. To date, much research has been performed comparing regression testing techniques, but very little research has been performed to aid practitioners and researchers in choosing the most cost-effective technique for a particular regression testing session. One recent study investigated this problem and proposed Adaptive Regression Testing (ART) strategies to aid practitioners in choosing the most cost-effective technique for a specific version of a software system.

Model-Based Exploratory Testing: A Controlled Experiment, Christopher J. Schaefer Jan 2013

Model-Based Exploratory Testing: A Controlled Experiment, Christopher J. Schaefer

Computer Science

Testing methods of software systems have been receiving more and more focus in recent years. Exploratory Testing (ET) is one such testing method. The advantages of ET are generally outweighed by its disadvantages, mainly the time necessary to perform it. Multiple test automation methods and frameworks offer time saving benefits, in generally what is already a limited amount of time in the development process. In this study we propose Model-based Exploratory Testing (MBET), an approach that incorporates the advantages of ET and the time saving automation of Model-based Testing (MBT). To assess our approach, we conducted a controlled experiment focusing …
