APPLYING REQUIREMENT BASED COMPLEXITY FOR THE ESTIMATION OF SOFTWARE DEVELOPM...cscpconf
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.

IRJET- Software Bug Prediction using Machine Learning ApproachIRJET Journal
This document discusses using machine learning techniques to predict software bugs based on historical data. Specifically, it compares the performance of the Naive Bayes and J48 (Decision Tree) classifiers on bug prediction. The Naive Bayes and J48 classifiers are trained on datasets from real software projects containing product metrics and defect information. Their performance is evaluated based on accuracy, F-measure, recall, and precision. The results show that the J48 Decision Tree classifier has the best performance and is more accurate at predicting bugs compared to the Naive Bayes classifier. The authors conclude that machine learning is an effective approach for software bug prediction and can improve software quality if used early in the development process.

Software size estimation at early stages of project development holds great significance to meet
the competitive demands of software industry. Software size represents one of the most
interesting internal attributes which has been used in several effort/cost models as a predictor
of effort and cost needed to design and implement the software. The whole world is focusing
towards object oriented paradigm thus it is essential to use an accurate methodology for
measuring the size of object oriented projects. The class point approach is used to quantify
classes which are the logical building blocks in object oriented paradigm. In this paper, we
propose a class point based approach for software size estimation of On-Line Analytical
Processing (OLAP) systems. OLAP is an approach to swiftly answer decision support queries
based on multidimensional view of data. Materialized views can significantly reduce the
execution time for decision support queries. We perform a case study based on the TPC-H
benchmark which is a representative of OLAP System. We have used a Greedy based approach
to determine a good set of views to be materialized. After finding the number of views, the class
point approach is used to estimate the size of an OLAP System The results of our approach are
validated.

An unsupervised feature selection algorithm with feature ranking for maximizi...Asir Singh
Prediction plays a vital role in decision making. Correct prediction leads to right decision making to save the life, energy,
efforts, money and time. The right decision prevents physical and material losses and it is practiced in all the fields including medical,
finance, environmental studies, engineering and emerging technologies. Prediction is carried out by a model called classifier. The
predictive accuracy of the classifier highly depends on the training datasets utilized for training the classifier. The irrelevant and
redundant features of the training dataset reduce the accuracy of the classifier. Hence, the irrelevant and redundant features must be
removed from the training dataset through the process known as feature selection. This paper proposes a feature selection algorithm
namely unsupervised learning with ranking based feature selection (FSULR). It removes redundant features by clustering and eliminates
irrelevant features by statistical measures to select the most significant features from the training dataset. The performance of this
proposed algorithm is compared with the other seven feature selection algorithms by well known classifiers namely naive Bayes (NB),
instance based (IB1) and tree based J48. Experimental results show that the proposed algorithm yields better prediction accuracy for
classifiers.
This document discusses various techniques for estimating software project costs, schedules, and sizes. It covers function point analysis, lines of code estimation, productivity models like COCOMO, and probabilistic techniques like PERT estimation. Key approaches mentioned include analogies, decomposition, mathematical models, mean schedule dates, and probability distributions.
This document describes a web application called the Course Outcome Attainment Estimation System. The system allows faculty to accurately calculate course outcome attainment percentages and reduces the time required compared to manual calculations. Student continuous assessment marks, assignment marks, and other data are entered and stored in a database. The system then calculates individual course outcome percentages and graphs. It generates the overall course outcome attainment percentage using direct internal and external assessment marks. The objectives are to create an easy-to-use system that accurately calculates results with less time than manual methods. It also allows storing and printing results for future use.
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
ANFIS Model.

Abstract
Lean Six Sigma projects and the quality engineering profession have to deal with an extensive selection of tools
most of them requiring specialized training. The increased availability of standard statistical software motivates the
use of advanced data science techniques to identify relationships between potential causes and project metrics. In
these circumstances, Symbolic Regression has received increased attention from researchers and practitioners to
uncover the intrinsic relationships hidden within complex data without requiring specialized training for its
implementation. The objective of this paper is to evaluate the advantages and drawbacks of using computer assisted
Symbolic Regression within the Analyze phase of a Lean Six Sigma project. An application of this approach in a
service industry project is also presented.

1. Introduction
Lean Six Sigma (LSS) has become a well-known hybrid methodology for quality and productivity improvement in
organizations. Its wide adoption in several industries has shaped Process Innovation and Operational Excellence
initiatives, enabling LSS to become a main topic in quality practitioner sites of interest [1], recognized Six Sigma
(SS) certification body of knowledge contents [2], and professional society conferences [3].
However LSS projects and the quality engineering profession have to deal with an extensive selection of tools most
of them requiring specialized training. To assist LSS practitioners it is common to categorize tools based on the
traditional DMAIC model which stands for Define, Measure, Analyze, Improve, and Control phases. Table 1
presents an overview of the main tools that are commonly used in each phase of a LSS project, allowing team
members to progressively develop an understanding between realizing each phase’s intent and how the selected
tools can contribute to that purpose.
This paper focuses on the Analyze phase where tools for statistical model building are most likely to be selected.
The increased availability of standard statistical software motivates the use of advanced data science techniques to
identify relationships between potential causes and project metrics. In these circumstances Symbolic Regression
(SR) has received increased attention from researchers and practitioners even though SR is still in an early stage of
commercial availability.

This document analyzes and compares maintainability metrics for aspect-oriented software (AOS) and object-oriented software (OOS) using five projects. It discusses metrics like number of children, depth of inheritance tree, lack of cohesion of methods, weighted methods per class, and lines of code. The results show that for most metrics like NOC, DIT, LCOM, and WMC, the mean values are higher for OOS compared to AOS, indicating that AOS is generally more maintainable based on these metrics. LOC is also lower on average for AOS. The study concludes that an AOP version is more maintainable than an OOP version according to the chosen metrics.
This document describes a student result system project created using C programming language.

The source code implements functions for the main menu, record insertion, display, sorting, searching, and average calculation. UML diagrams show the design of the student record class and interaction between functions.
1. Software project estimation involves decomposing a project into smaller problems like major functions and activities. Estimates can be based on similar past projects, decomposition techniques, or empirical models.
2. Accurate estimates depend on properly estimating the size of the software product using techniques like lines of code, function points, or standard components. Baseline metrics from past projects are then applied to the size estimates.
3. Decomposition techniques involve estimating the effort needed for each task or function and combining them. Process-based estimation decomposes the software process into tasks while problem-based estimation decomposes the problem.
ANALYZABILITY METRIC FOR MAINTAINABILITY OF OBJECT ORIENTED SOFTWARE SYSTEMIAEME Publication
Analyzability is one of the major factors in the prediction of maintainability aspect that can improve the quality of the intended software solution in an appropriate manner. In fact, the right analyzability measure will go a long way in decreasing the inadequacies and deficiencies through identification of the modified parts and failure causes in the software system. The analyzability metric identification is not possible in every software solution because of its non- functional nature in the real world, but in object-oriented software system there is an opportunity to find out the analyzability metric in the form of class inheritance hierarchies. In this research paper, the researcher measured the analyzability factor for the object-oriented software systems and also validated in accordance with the famed weyker’s properties. The proposed analyzability metric here is intended to lead the new developments in object-oriented software maintainability parameter in future and help the new researchers do their research the right way thus eventually achieving the quality aspect of the objectoriented software system and fulfilling the needs of the users.

Rail transport is one of the important modes of transport in India. Now a days we
see that there are railways that are present for the long as well as short distance
travelling which makes the life of the people easier. When compared to other
means of transport, a railway is the cheapest means of transport. The maintenance
of the railway database also plays a major role in the smooth running of this
system. The Online Train Ticket Management System will help in reserving the
tickets of the railways to travel from a particular source to the destination.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications

Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

INTRODUCTION
Function-oriented software metrics use a measure of the functionality delivered
by the application as a normalization value. Since ‘functionality’ cannot be
measured directly, it must be derived indirectly using other direct measures.
Function-oriented metrics were first proposed by Albrecht, who suggested a
measure called the function point. Function points are derived using an empirical
relationship based on countable (direct) measures of software's information
domain and assessments of software complexity.
Function points are computed by completing the table as shown below. Five
information domain characteristics are determined and counts are provided in the
appropriate table location. Information domain values are defined in the
following manner:

5. Dr. G. Prasuna, Associate Professor, CSE Dept., St. Ann's College of Engineering and Technology, Chirala
Number of user inputs. Each user input that provides distinct application oriented data to thesoftware is
counted. Inputs should be distinguished from inquiries, which are counted separately.
Number of user outputs. Each user output that provides application oriented information tothe user is counted.
In this context output refers to reports, screens, error messages, etc. Individual data items within a report are not
counted separately.
Number of user inquiries. An inquiry is defined as an on-line input that results in the generation of some
immediate software response in the form of an on-line output. Each distinct inquiry is counted.
Number of files. Each logical master file (i.e., a logical grouping of data that may be one partof a large database
or a separate file) is counted.
Number of external interfaces. All machine readable interfaces (e.g., data files on storagemedia) that are used
to transmit information to another system are counted.
Once these data have been collected, a complexity value is associated with each count. Organizations that use
function point methods develop criteria for determining whether a particular entry is simple, average, or
complex. Nonetheless, the determination of complexity is somewhat subjective.

FUNCTION POINTS(FP) COMPUTATION
To compute function points (FP), the following relationship is used:
FP = count total * [0.65 + 0.01 Σ ( Fi)]
where count total is the sum of all FP entries .
The Fi (i = 1 to 14) are "complexity adjustment values" based on responses to the following questions :
1. Does the system require reliable backup and recovery?
2. Are data communications required?
3. Are there distributed processing functions?
4. Is performance critical?
5. Will the system run in an existing, heavily utilized operational environment?
6. Does the system require on-line data entry?
7. Does the on-line data entry require the input transaction to be built over multiple screens or operations?
8. Are the master files updated on-line?
9. Are the inputs, outputs, files, or inquiries complex?
10. Is the internal processing complex?
11. Is the code designed to be reusable?
12. Are conversion and installation included in the design?
13. Is the system designed for multiple installations in different organizations?
14. Is the application designed to facilitate change and ease of use by the user?
7. Dr. G. Prasuna, Associate Professor, CSE Dept., St. Ann's College of Engineering and Technology, Chirala
Each of these questions is answered using a scale that ranges from 0 (not important or applicable) to 5 (absolutely
essential). The constant values in Equation and the weighting factors that are applied to information domain counts
are determined empirically.
Once function points have been calculated, they are used in a manner analogous to LOC as a way to normalize
measures for software productivity, quality, and other attributes:
Errors per FP.
Productivity = FP/ Person-Month
Quality = No of faults / FP
Cost= $/FP
Documentation = Pages count / FP.
ADVANTAGES:
This method is independent of programming languages.
It is based on the data which can be obtained in early stage of project
DISADVANTAGES:
This method is more suitable for Business systems and can be developed for that domain
Many aspects of this method are not validated
The functional point has no significant ant meaning, it’s just a numerical value.

Problem:
Given the following values, compute function point when all
complexity adjustment factor (CAF) and weighting factors are average.
User Input = 45
User Output = 50
User Inquiries = 35
User Files = 8
External Interface = 4
9. Dr. G. Prasuna, Associate Professor, CSE Dept., St. Ann's College of Engineering and Technology, Chirala
Solution:
As complexity adjustment factor is average (given in question), hence, scale = 3.
∑Fi = 14 * 3 = 42 where i=1 to 14
CAF = 0.65 + ( 0.01 * 42 ) = 1.07
As weighting factors are also average (given in question) hence we will multiply
each individual function point to corresponding values in TABLE.
Count_total = (45*4) + (50*5) + (35*4) + (8*10) + (4*7)
= 180 + 250 + 140 + 80 + 28 = 678
Function Point = Count_total *[0.65+(0.01 *∑Fi )] where i=1 to 14
= 678 *[ 0.65 +(0.01 * 42)] = 725.46 FP

After calculating Function points of an application, we can estimate the effort easily.
For example, if application with 100 Function Points requires 25 PM Effort, we can
estimate the effort for our application having 725.46 Function Points.
For 100 Function Points application Effort is 25 PM
For 725.46 Function Points application Effort = (725.46/100)*25 =181.36 PM
