ONE HIDDEN LAYER ANFIS MODEL FOR OOS DEVELOPMENT EFFORT ESTIMATION
ONE HIDDEN LAYER ANFIS MODEL FOR OOS DEVELOPMENT EFFORT ESTIMATIONInternational Journal of Technical Research & Application
In the present paper, applicability and
capability of A.I techniques for effort estimation prediction has
been investigated. It is seen that neuro fuzzy models are very
robust, characterized by fast computation, capable of handling
the distorted data. Due to the presence of data non-linearity, it is
an efficient quantitative tool to predict effort estimation. The one
hidden layer network has been developed named as OHLANFIS
using MATLAB simulation environment.
Here the initial parameters of the OHLANFIS are
identified using the subtractive clustering method. Parameters of
the Gaussian membership function are optimally determined
using the hybrid learning algorithm. From the analysis it is seen
that the Effort Estimation prediction model developed using
OHLANFIS technique has been able to perform well over normal

Today, Software measurement are based on various techniques such that neural network, Genetic
algorithm, Fuzzy Logic etc. This study involves the efficiency of applying support vector machine using
Gaussian Radial Basis kernel function to software measurement problem to increase the performance and
accuracy. Support vector machines (SVM) are innovative approach to constructing learning machines that
Minimize generalization error. There is a close relationship between SVMs and the Radial Basis Function
(RBF) classifiers. Both have found numerous applications such as in optical character recognition, object
detection, face verification, text categorization, and so on. The result demonstrated that the accuracy and
generalization performance of SVM Gaussian Radial Basis kernel function is better than RBFN. We also
examine and summarize the several superior points of the SVM compared with RBFN.

Accurately estimating the software size, cost, effort and schedule is probably the biggest
challenge facing software developers today. It has major implications for the management of
software development because both the overestimates and underestimates have direct impact for
causing damage to software companies. Lot of models have been proposed over the years by
various researchers for carrying out effort estimations. Also some of the studies for early stage
effort estimations suggest the importance of early estimations. New paradigms offer alternatives
to estimate the software development effort, in particular the Computational Intelligence (CI)
that exploits mechanisms of interaction between humans and processes domain
knowledge with the intention of building intelligent systems (IS). Among IS,
Artificial Neural Network and Fuzzy Logic are the two most popular soft computing techniques
for software development effort estimation. In this paper neural network models and Mamdani
FIS model have been used to predict the early stage effort estimations using the student dataset.
It has been found that Mamdani FIS was able to predict the early stage efforts more efficiently in
comparison to the neural network models based models.
Software Cost Estimation Using Clustering and Ranking Scheme
Software cost estimation is an important task in the software design and development process.
Planning and budgeting tasks are carried out with reference to the software cost values. A variety of
software properties are used in the cost estimation process. Hardware, products, technology and
methodology factors are used in the cost estimation process. The software cost estimation quality is
measured with reference to the accuracy levels.
Software cost estimation is carried out using three types of techniques. They are regression based
model, anology based model and machine learning model. Each model has a set of technique for the
software cost estimation process. 11 cost estimation techniques fewer than 3 different categories are
used in the system. The Attribute Relational File Format (ARFF) is used maintain the software product
property values. The ARFF file is used as the main input for the system.
The proposed system is designed to perform the clustering and ranking of software cost
estimation methods. Non overlapped clustering technique is enhanced with optimal centroid estimation
mechanism. The system improves the clustering and ranking process accuracy. The system produces
efficient ranking results on software cost estimation methods.
Application of Genetic Algorithm in Software Engineering: A Review

Review on Algorithmic and Non Algorithmic Software Cost Estimation Techniques
Effective software cost estimation is the most challenging and important activities in software development. Developers want a simple and accurate method of efforts estimation. Estimation of the cost before starting of work is a prediction and prediction always not accurate. Software effort estimation is a very critical task in the software engineering and to control quality and efficiency a suitable estimation technique is crucial. This paper gives a review of various available software effort estimation methods, mainly focus on the algorithmic model and non algorithmic model. These existing methods for software cost estimation are illustrated and their aspect will be discussed. No single technique is best for all situations, and thus a careful comparison of the results of several approaches is most likely to produce realistic estimation. This paper provides a detailed overview of existing software cost estimation models and techniques. This paper presents the strength and weakness of various cost estimation methods. This paper focuses on some of the relevant reasons that cause inaccurate estimation.

Benchmarking machine learning techniques
Machine Learning approaches are good in solving problems that have less information. In most cases, the
software domain problems characterize as a process of learning that depend on the various circumstances
and changes accordingly. A predictive model is constructed by using machine learning approaches and
classified them into defective and non-defective modules. Machine learning techniques help developers to
retrieve useful information after the classification and enable them to analyse data from different
perspectives. Machine learning techniques are proven to be useful in terms of software bug prediction. This
study used public available data sets of software modules and provides comparative performance analysis
of different machine learning techniques for software bug prediction. Results showed most of the machine
learning methods performed well on software bug datasets.

Software metrics validation
In the software measurement validations, assessing the validation of software metrics in software
engineering is a very difficult task due to lack of theoretical methodology and empirical methodology [41,
44, 45]. During recent years, there have been a number of researchers addressing the issue of validating
software metrics. At present, software metrics are validated theoretically using properties of measures.
Further, software measurement plays an important role in understanding and controlling software
development practices and products. The major requirement in software measurement is that the measures
must represent accurately those attributes they purport to quantify and validation is critical to the success
of software measurement. Normally, validation is a collection of analysis and testing activities across the
full life cycle and complements the efforts of other quality engineering functions and validation is a critical
task in any engineering project. Further, validation objective is to discover defects in a system and assess
whether or not the system is useful and usable in operational situation. In the case of software engineering,
validation is one of the software engineering disciplines that help build quality into software. The major
objective of software validation process is to determine that the software performs its intended functions
correctly and provides information about its quality and reliability. This paper discusses the validation
methodology, techniques and different properties of measures that are used for software metrics validation.
In most cases, theoretical and empirical validations are conducted for software metrics validations in
software engineering [1-50].

APPLYING REQUIREMENT BASED COMPLEXITY FOR THE ESTIMATION OF SOFTWARE DEVELOPM...
The need of computing the software complexity in requirement analysis phase of software
development life cycle (SDLC) would be an enormous benefit for estimating the required
development and testing effort for yet to be developed software. Also, a relationship between
source code and difficulty in developing a source code are also attempted in order to estimate the
complexity of the proposed software for cost estimation, man power build up, code and
developer’s evaluation. Therefore, this paper presents a systematic and an integrated approach
for the estimation of software development and testing effort on the basis of improved
requirement based complexity (IRBC) of the proposed software. The IRBC measure serves as the
basis for estimation of these software development activities to enable the developers and
practitioners to predict the critical information about the software development intricacies and
obtained from software requirement specification (SRS) of proposed software. Hence, this paper
presents an integrated approach, for the prediction of software development and testing effort
using IRBC. For validation purpose, the proposed measures are categorically compared with
various established and prevalent practices proposed in the past. Finally, the results obtained, validates the claim, for the approaches discussed in this paper, for estimation of software development and testing effort, in the early phases of SDLC appears to be robust, comprehensive, early alarming and compares well with other measures proposed in the past.
Cause-Effect Graphing: Rigorous Test Case Design
A tester’s toolbox today contains a number of test case design techniques—classification trees, pairwise testing, design of experiments-based methods, and combinatorial testing. Each of these methods is supported by automated tools. Tools provide consistency in test case design, which can increase the all-important test coverage in software testing. Cause-effect graphing, another test design technique, is superior from a test coverage perspective, reducing the number of test cases needed to provide excellent coverage. Gary Mogyorodi describes these black box test case design techniques, summarizes the advantages and disadvantages of each technique, and provides a comparison of the features of the tools that support them. Using an example problem, he compares the number of test cases derived and the test coverage obtained using each technique, highlighting the advantages of cause-effect graphing. Join Gary to see what new techniques you might want to add to your toolbox.

This paper presents a Multi-objective Hyper-heuristic Evolutionary Algorithm (MHypEA) for the solution
of Scheduling and Inspection Planning in Software Development Projects. Scheduling and Inspection
planning is a vital problem in software engineering whose main objective is to schedule the persons to
various activities in the software development process such as coding, inspection, testing and rework in
such a way that the quality of the software product is maximum and at the same time the project make span
and cost of the project are minimum. The problem becomes challenging when the size of the project is
huge. The MHypEA is an effective metaheuristic search technique for suggesting scheduling and inspection
planning. It incorporates twelve low-level heuristics which are based on different methods of selection,
crossover and mutation operations of Evolutionary Algorithms. The selection mechanism to select a lowlevel
heuristic is based on reinforcement learning with adaptive weights. The efficacy of the algorithm has
been studied on randomly generated test problem.

TOWARDS PREDICTING SOFTWARE DEFECTS WITH CLUSTERING TECHNIQUES
The purpose of software defect prediction is to improve the quality of a software project by building a
predictive model to decide whether a software module is or is not fault prone. In recent years, much
research in using machine learning techniques in this topic has been performed. Our aim was to evaluate
the performance of clustering techniques with feature selection schemes to address the problem of software
defect prediction problem. We analysed the National Aeronautics and Space Administration (NASA)
dataset benchmarks using three clustering algorithms: (1) Farthest First, (2) X-Means, and (3) selforganizing map (SOM). In order to evaluate different feature selection algorithms, this article presents a
comparative analysis involving software defects prediction based on Bat, Cuckoo, Grey Wolf Optimizer
(GWO), and particle swarm optimizer (PSO). The results obtained with the proposed clustering models
enabled us to build an efficient predictive model with a satisfactory detection rate and acceptable number
of features.

Determining risky software projects early is a very important factor for project success. In this study it is aimed to choose the most correctly resulting modelling method that will be useful for early prediction of risky software projects to help companies to avoid losing time and money on unsuccessful projects and also facing legal requirements because of not being able to fullfill their responsibilites to their customers While making the research for this subject, it is seen that in previous researches, usually traditional modelling techniques were preferred. But it is observed that these methods were mostly resulted with high misclassification ratio. To overcome this problem, this study proposes a three-layered neural network (NN) architecture with a backpropagation algorithm. NN architecture was trained by using two different data sets which were OMRON data set (collected by OMRON) and 2016-2020 ES.LV data set (collected by the authors) separately. For the made of this study firstly the most relevant classification method (Gaussian Naive Bayes Algorithm) and the most relevant neural network method (Scaled Conjugate Gradient Backpropagation Algorithm) was chosen and both data sets were trained by using each method seperately for the purpose of observing which type of modelling architecture would give better results. Experimental results of this study showed that the neural network approach is useful for predicting whether a project is risky or not risky.

techniques used to predict software defects such as regression, association rules, clustering, and classification. This paper is concerned
with classification based software defect prediction. This paper investigates the effectiveness of using a radial basis function neural
network and a probabilistic neural network on prediction accuracy and defect prediction. The conclusions to be drawn from this work is
that the neural networks used in here provide an acceptable level of accuracy but a poor defect prediction ability. Probabilistic neural
networks perform consistently better with respect to the two performance measures used across all datasets. It may be advisable to use
a range of software defect prediction models to complement each other rather than relying on a single technique.
Decision support systems, Supplier selection, Information systems, Boolean al...
For organizations operating with number of products/services and number of suppliers, to select the right
supplier meeting all their requirements will be a challenging job. Such organizations need a good
decision support system to evaluate the suppliers effectively. Several decision support systems have been
reported to deal with complex selection process to decide the right supplier. Many mathematical models
have also been developed. This paper presents a new method, named as Bit Decision Making (BDM)
method, which treats such complex system of decision making as a collection and sequence of reasonable
number of meaningful and manageable sub-systems by identifying and processing the relevant decision
criteria in each sub-system. Help of Boolean logic and Boolean algebra is taken to assign binary digit
values to the selection criteria and generate mathematical equations that correlate the inputs to the output
at each stage of decision making. Each sub-system with its own mathematical model has been treated as a
standardized decision sub-system for that phase of making decision in evaluating suppliers. The sequence
and connectivity of the sub-systems along with their outputs finally lead to selection of the best supplier. A
real-world case of evaluation of information technology (IT) tenders has been dealt with for application of
the proposed method. The paper discusses in detail the theory, methodology, application and features of
the new method.
Thesis Part I EMGT 698
Although there has been an extensive study over delivering, increasing and maintaining software quality, there has not been enough aide- mémoire on ‘Rating a Software‘s Quality’. This study would project the literature review thus far and also sculpt the scope and need for the evolution of a rating system of software quality for the future.
A simplified predictive framework for cost evaluation to fault assessment usi...
Software engineering is an integral part of any software development scheme which frequently encounters bugs, errors, and faults. Predictive evaluation of software fault contributes towards mitigating this challenge to a large extent; however, there is no benchmarked framework being reported in this case yet. Therefore, this paper introduces a computational framework of the cost evaluation method to facilitate a better form of predictive assessment of software faults. Based on lines of code, the proposed scheme deploys adopts a machine-learning approach to address the perform predictive analysis of faults. The proposed scheme presents an analytical framework of the correlation-based cost model integrated with multiple standards machine learning (ML) models, e.g., linear regression, support vector regression, and artificial neural networks (ANN). These learning models are executed and trained to predict software faults with higher accuracy. The study considers assessing the outcomes based on error-based performance metrics in detail to determine how well each learning model performs and how accurate it is at learning. It also looked at the factors contributing to the training loss of neural networks. The validation result demonstrates that, compared to logistic regression and support vector regression, neural network achieves a significantly lower error score for software fault prediction.
The Impact of Software Complexity on Cost and Quality - A Comparative Analysi...
Early prediction of software quality is important for better software planning and controlling. In early
development phases, design complexity metrics are considered as useful indicators of software testing
effort and some quality attributes. Although many studies investigate the relationship between design
complexity and cost and quality, it is unclear what we have learned beyond the scope of individual studies.
This paper presented a systematic review on the influence of software complexity metrics on quality
attributes. We aggregated Spearman correlation coefficients from 59 different data sets from 57 primary
studies by a tailored meta-analysis approach. We found that fault proneness and maintainability are most
frequently investigated attributes. Chidamber & Kemerer metric suite is most frequently used but not all of
them are good quality attribute indicators. Moreover, the impact of these metrics is not different in
proprietary and open source projects. The result provides some implications for building quality model
across project type.
A Model To Compare The Degree Of Refactoring Opportunities Of Three Projects ...
Refactoring is applied to the software artifacts so as to improve its internal structure, while preserving its
external behavior. Refactoring is an uncertain process and it is difficult to give some units for
measurement. The amount to refactoring that can be applied to the source-code depends upon the skills of
the developer. In this research, we have perceived refactoring as a quantified object on an ordinal scale of
measurement. We have a proposed a model for determining the degree of refactoring opportunities in the
given source-code. The model is applied on the three projects collected from a company. UML diagrams
are drawn for each project. The values for source-code metrics, that are useful in determining the quality of
code, are calculated for each UML of the projects. Based on the nominal values of metrics, each relevant
UML is represented on an ordinal scale. A machine learning tool, weka, is used to analyze the dataset,
imported in the form of arff file, produced by the three projects

A NOVEL APPROACH TO ERROR DETECTION AND CORRECTION OF C PROGRAMS USING MACHIN...
There has always been a struggle for programmers to identify the errors while executing a program- be it
syntactical or logical error. This struggle has led to a research in identification of syntactical and logical
errors. This paper makes an attempt to survey those research works which can be used to identify errors as
well as proposes a new model based on machine learning and data mining which can detect logical and
syntactical errors by correcting them or providing suggestions. The proposed work is based on use of
hashtags to identify each correct program uniquely and this in turn can be compared with the logically
incorrect program in order to identify errors.
Function Point Software Cost Estimates using Neuro-Fuzzy technique
Software estimation accuracy is among the greatest challenges for software developers. As Neurofuzzy based system is able to approximate the non-linear function with more precision so it is used as a soft computing approach to generate model by formulating the relationship based on its training. The approach presented in this paper is independent of the nature and type of estimation. In this paper, Function point is used as algorithmic model and an attempt is being made to validate the soundness of Neuro fuzzy technique using ISBSG and NASA project data.

GALE: Geometric active learning for Search-Based Software Engineering
Multi-objective evolutionary algorithms (MOEAs) help software engineers find novel solutions to complex problems. When automatic tools explore too many options, they are slow to use and hard to comprehend. GALE is a near-linear time MOEA that builds a piecewise approximation to the surface of best solutions along the Pareto frontier. For each piece, GALE mutates solutions towards the better end. In numerous case studies, GALE finds comparable solutions to standard methods (NSGA-II, SPEA2) using far fewer evaluations (e.g. 20 evaluations, not 1,000). GALE is recommended when a model is expensive to evaluate, or when some audience needs to browse and understand how an MOEA has made its conclusions.

how to sell pi coins in South Korea profitably.
Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.
How can i find a pi vendor/merchant?
Well for those who haven't traded with a pi merchant or who don't already have one. I will leave the telegram id of my personal pi merchant who i trade pi with.

The European Unemployment Puzzle: implications from population aging
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.
