ABSTRACT : Due to the huge growth and expansion of the World Wide Web, a large amount of
information is available online. Through Search engines we can easily access this information with
the help of Search engine indexing. To facilitate fast and accurate information retrieval search
engine indexing collects, parses, and store data. This paper explains partitioning clustering technique
for implementing indexing phase of search engine. Clustering techniques are widely used for
grouping a set of objects in such a way that objects in the same group are more to each other than to
those in other groups in "Web Usage Mining". Clustering methods are largely divided into two
groups: hierarchical and partitioning methods. This paper proposes the k–mean partitioning method
of clustering and also provide a comparison of k–mean clustering and Single link HAC .

Study Of Data Mining Algorithm For Cloud Computing
ABSTRACT
This technical paper consists of the study of data mining algorithm in cloud computing. Cloud
Computing is an environment created in user's machine from online application stored in clouds and
run through web browser. Therefore, it is essential to manage user's data efficiently. Data mining
also known as knowledge discovery is the process of analyzing data from different perspectives and
summarizing it into useful information where the information can be used to increase revenue, cut
costs of implementation and maintenances, or all. Data mining software and/or algorithms is one of
a number of analytical tools for analyzing data. It allows users to analyze data from many different
dimensions or angles, categorize it, and summarize the relationships identified. Technically, data
mining is the process of finding correlations or patterns among dozens of fields in large relational
databases. The process of mining data can be done in many ways; this paper discusses the
theoretical study of two algorithms K–means and Apriori, their explanation using flow chart and
pseudo code, and comparison for time and space complexity of the two for the dataset of an "Online
Retail Shop".

Digital Imaging Technologies Have Become Indispensable...
ABSTRACT
Digital imaging technologies have become indispensable components for clinical procedures. Major
advances in the field of medical imaging and computer technology have created opportunity for
quantitative analyses of medical images and provided powerful techniques to probe the structure,
pathology and function of the human body . In medical applications, skilled operators usually
extract the desired regions that may be anatomically separate but statistically indistinguishable. It is
subjected to manual errors and biases, which is time consuming, and has poor reproducibility. The
problem faced in clustering is the identification of clusters in given data. A widely used method for
clustering is based on K–means in which the data is partitioned into K number of clusters. In this
method, clusters are predefined which is highly dependent on the initial identification of elements
representing the clusters well. Several researchers in clustering has focused on improving the
clustering process such that the clusters are not dependent on the initial identification of cluster
representation.

A Comparative Analysis of Force Directed Layout Algorithms for Biological Networks
Brief Description:
I will conduct a comparative analysis of multiple force–directed algorithms used to identify clusters
in biological networks. The analysis will consider topics such as the algorithm process, amount of
preprocessing, complexity, and flexibility of the algorithms for different types and sizes of data. K–
Means, SPICi, Markov Clustering, RNSC, and PBD will be used for the comparison. I will identify
the best algorithm according to my analysis for each type of input data studied.
Background: how to determine if a clustering algorithm is good/if a cluster is good→ modularity
Proteins control all processes within the cell. Though some proteins work individually, most work in
groups to participate in some biochemical event. Examples of these processes include protein–
protein interaction networks, metabolome, correlation/co–expression values, synthetic lethality, and
signal transduction (Cooper, lecture). The study of proteins that work together can allow a greater
understanding of cellular processes. New pathways, proteins, or systems can be identified via
network analysis. In order to recognize groups of proteins that work together, a biological network,
called a graph, is formed.
The study of graphs has a prominent history in mathematics and statistics. Graph Theory

In order to detect the drifting concept we are using sliding window technique.
Sliding window
It is the one of the most important technique in data mining which removes the obsolete transactions
in the current window. With this technique we can test the latest data points in the present window

Now–a–days usage of data is more so that will find the clusters in the huge data is a big task. As a
result we are using practical categorical representative named Node Importance Representative
(NIR). It represent clusters by measuring the importance of each attribute value in the clusters.
Based on this we propose Drift Concept Detection (DCD).
1.3 DRIFT CONCEPT DETECTION (DCD)
In DCD, the incoming categorical data points at the present sliding window are first allocated into
the corresponding proper cluster at the last clustering result, and the number of outliers that are not
able to be assigned into any cluster is counted. After that, the distribution of clusters and outliers
between the last clustering result and the current temporal clustering result are compared with each
other. If the distribution is changed (exceeding some criteria), the concepts are said to drift

Abstract – The current classroom utilization of University of Lethbridge is around 50%. Now, they
are planning to increase it up to 80%. The data of classrooms for last five years are available that
includes Course name, Course Level, Approved size, Sitting types, Actual enrollment and so on.
Now, our job is to find out classroom utilization trend, Compare approved and actual enrollment
values, find patterns among the classroom size, level and schedule. Above all, based on the data we
have to take decision on how we can change the schedule of the classes and their length to have a
better utilization yield. We have worked ... Show more content on Helpwriting.net ...
Second, even though two universities may have same utilization rates but they may have different
areas of classroom per student. Third, there is no standard framework to find out how all the
universities are doing year by year. We do not know the factors that influence the classroom size,
student enrollment and utilization. There are a lot of questions to be answer. Now, our job is to find
out classroom utilization trend, Compare approved and actual enrollment values, find patterns
among the classroom size, level and schedule. Above all, based on the data we have to take decision
on how we can change the schedule of the classes and their length to have a better utilization yield.
Problem description and prior work
There have been significant works related to Multidimensional data mining. But there is hardly any
work to find any work related to classroom utilization trend associating multidimensional pattern.
But here we have presented some of the data mining technique that we may apply to this field.
Apriori algorithm is one of the notable works for mining multidimensional association rules. A
recent study of Khare et al. [3] has implemented multidimensional association rules using Boolean
relational calculus to discover frequent predicate sets. For the purpose of retrieving pattern from
database, the relational database is first transformed into Boolean matrix by setting us a Boolean
matrix Am*n , where m (are records) and n ( are different dimension

This technology had been embedded in different products and also the company's own special–
purpose products. Dan woods (2010) quoted another example of a new company; WiseWindow had
been applying this analysis into social media content. This analysis had helped the company to
obtain clues to the future trends and allow WiseWindow to connect its engine to thousands of
streams of social media and traking millions of comments a day. WiseWindow had found a way to
examine the course of growth of clusters and turn this analysis into leading indicators (Dan woods,
2010).
2.1.2 Advantages of cluster analysis
– It is the easiest method for companies to collect data for analysis. As companies cannot connect
with all their customers, they normally divide the market into different groups with similar needs
and wants (E.Mooi and M.Sarstedt, 2011). Firms would then target each segment by positioning
themselves in a unique segment such as Ferrari positioning in the high end sports car market.
– This analysis is also cost effective as it would only require a sample from the population.
– This method of analysis could also be used for special context. There are research and studies that
uses this analysis to evaluate on special context, such as evaluating supermarket shopping paths
(Larson et al. 2005) or obtaining employer's branding strategies (Moroko & Uncles,

It is like a database where crawler searches the documents and put into it. It is used to store the data
which is search by the crawler. It provides the documents as a input to the clustering algorithm to
make the cluster. 5.5.2 Clustering This phase take the input of documents to make the cluster. To
make the cluster I have applied an agglomerative approach which is a hierarchal approach. It take 2
document and make one cluster and produce the hierarchy. With this hierarchy approach a hierarchy
of cluster like mega cluster ,super clusters are generated by itself which help in the searching in
efficient way. Now it can create the index at each level. As it is taking the common words in clusters
then index at higher level will be smelled. When the user search for matter it will go to the higher
index. As the user put the more words in the query our search will get narrowed and user will get the
particular documents which is relevant. This can be explained with the help of an example. Example
Fig. 5.5 Hierarchal clustering Now it has hierarchy of clusters and at each level it has index. At
higher level it has smaller index which will take less time in searching. Now when the user searches

This paper presents the analysis of Kmeans and K–Medians clustering algorithm in detecting
outliers. Clustering is generally used in pattern recognition where if a user wants to search for some
particular pattern, clustering reduces the searching load. The k–means clustering and kmedians
clustering algorithm's performance in detecting outliers are analysed here. K–means clustering
clusters the similar data with the help of the mean value and squared error criterion. Kmedians is
similar to k–means algorithm but median values are calculated there. Outliers are the one different

Also it includes resizing of image data. 2.2 Image Segmentation: Image Segmentation is concerned
about segmenting the image into various segments using various techniques. In early days a semi–
automatic approach was being used to detect the exact boundaries of the brain tumor. However the
semiautomatic methods were not very successful as they had human induced errors and were time
consuming. A better application of tumor detection was made by introducing fully automated tumor
detection systems. Various methods have been proposed like Markov random fields method, Fuzzy
c–means (FCM) clustering, Otsu's thresholding, K–Mean's, neural network. In this project, four
different algorithms namely Otsu's method, Thresholding, K–means method and Fuzzy c–means and
PSO have been used for designing the brain tumor extraction system. Various segmentation
techniques which will be used in this project to segregate the different regions on the basis of
interest are described as follows: a) K–means: K–means is a clustering technique which aims to
partition a set of observations so as to minimize the within cluster sum of squares (WCSS). The
evaluating function for an image a (m, n) is given as: c(i)=Arg min|mxy2–nxy2| Where i is the no. of
clusters in which the image is to be partitioned. b) Otsu's Method: Otsu's Method divides the image
into two classes of regions namely foreground and background. The background and foreground
regions are selected using the following weighted

Advantages And Disadvantages Of Birch
BIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data
mining algorithm used to achieve hierarchical clustering over particularly huge data–sets. An
advantage of Birch is its capacity to incrementally and dynamically cluster incoming, multi–
dimensional metric data points in an effort to generate the best quality clustering for a given set of
resources (memory and time constraints). In most cases, Birch only requires a single scan of the
database. In addition, Birch is accepted as the, "first clustering algorithm proposed in the database
area to handle 'noise' (data points that are not part of the underlying pattern) efficiently.
Clustering Feature and CF Tree
The idea of Clustering Feature and CF tree are at the core of BIRCH'S incremental clustering. A
Clustering Feature is a triple summarizing the information that we maintain about a cluster.
Definition: Known N d–dimensions data points in a cluster :{Xi} where i=1, 2,..., N, the Clustering
Feature (CF) vector of cluster is defined as a triple:CF=(N,LS,SS), where N is the number of data
points in the cluster, LS is the linear sum of the N data points,i.e. N,Xi, and SS is the square sum of
the N data points i.e. submission of points n up to sum numbers Xi,.

Modifying the path to the leaf: After inserting "Ent" into a leaf, we must bring up to date the CF
information for each nonleaf entry on the path to the leaf. In the absence of a split, this basically
involves adding CF vectors to reflect the addition of "Ent". A leaf split requires us to insert a new
nonleaf entry into the parent node, to illustrate the newly created leaf. If the parent has space for this
entry, at all higher levels, we only need to bring up to date the CF vectors to reflect the addition of
"Ent". In general, however, we may have to split the parent as well, and soon up to the root. I f the

The Applications Of Cluster Analysis
Cluster Analysis
Introduction
Cluster analysis is the technique of grouping individuals into market segments on the basis of the
multivariate survey information (Dolnicar, 2003). Market segmentation remains one of the most
fundamental strategies for marketing. Organizations have to evaluate and choose the segments
wisely as their target as this will determine how the organization will be in the marketplace. The
quality of groupings management that an organization opts for is very paramount for the
organizational success, and it calls for professional use of techniques to determine useful segments.
Cluster analysis provides a plentiful of techniques employed in determining the number of segments
and their characteristics (Wedel & Kamakura, ... Show more content on Helpwriting.net ...
The organizations may also find helpful information on the Internet as there are many organizations
that put their data online.
2. Segmentation
After an organization gathers data from the market research, an organization then can embark on
market segmentation. As companies cannot connect with all of their potential customers, they need
to divide markets into groups of consumers, clients, or customers with similar needs or wants
(Sarstedt & Mooi, 2014). In other words, it is the grouping together of potential customers by their
willingness or their potential willingness in buying of the product you plan to sell. It is important
also to note that customers should not only be willing to make purchases from your company but
also they must also have sufficient income for them to qualify to become your customers. The
variables, in this case, which are vital include gender, age, home ownership, or loyalty to a particular
brand that you must overcome.
3. Carrying out market analysis
Once the relevant data is in hand, the next step is the carrying out of a final market analysis. In this
phase, you ought to be looking at a specific customer base that you will have to target with your
product. You need to do a keen observation to find out if among the clusters formed there are
custgome4rs large enough to justify your targeted marketing. After identifying the customers that
justify your criteria, and then you must start your marketing campaign. At this juncture, you

Cluster Analysis And Factor Analysis
Introduction
Cluster analysis has many different algorithms and methods to classify objects(Saunders, 1994).
One of the challenges faced by the researchers in different areas is to organize their data which is
possible by cluster analysis, it is a data analysis tool which focus on classifying the different objects
into groups such that the degree of association of the objects in a same group is highest if they
belong and least if they do not belong. Cluster analysis is a simple term, it does not identify any
statistical method or model and also there is no need to make any assumptions about distribution of
data, it is used to form groups of relevant variables without providing any explanation (Stockburger,
n.d.).
Despite their popularity, cluster analysis do provide a great opportunity for confusion and
misapplication when compared to factor analysis, discriminant analysis and multidimensional
scaling (Saunders, 1994). Both cluster analysis and factor analysis is used to organize the data into
clusters or onto factors, most of the researchers who are new to this concept may feel that these two
analyses are same, but they differ in many ways, the main objective of cluster analysis is to
categorize the data, whereas factor analysis simplify the data, it explains the correlation in a set of
data and relate variables to each other (Verial, n.d.). Cluster analysis and discriminant analysis are
the two terms where we can often get confused, the basic difference between them is

Evolutionary Computing Based Approach For Unsupervised...
Abstract– Genetic Algorithm (GA) is a stochastic randomized blind search and optimization
technique based on evolutionary computing that has already been proved to be robust and effective
from its outcome in solving problems from variety of application domains. Clustering is a vital
technique to extract meaningful and hidden information from the datasets. Clustering techniques
have a broad field of application including bioinformatics, image processing and data mining. In
order to the find the close association between the densities of data points, in the given dataset of
pixels of an image, clustering provides an easy analysis and proper validation. In this paper, we
propose an evolutionary computing based approach for unsupervised image clustering using elitist
GA (EGA) – a efficient variant of GA that segments an image into its constituent parts
automatically. The aim of this algorithm is to produce precise segmentation of images using
intensity information along with their neighbourhood relationships. Experimental results from
simulation study reveal that the algorithm generates good quality segmented image. Keywords–

Detection Of Brain Tumor Detection Essay
Abstract–A tumor is the growth in the abnormal tissue of the brain which causes damage to the other
cells necessary for functioning. Detection of brain tumor is a difficult task, as there are various
techniques involved in it. The active imaging resource used for brain tumor detection is Magnetic
Resonance Imaging (MRI). It is necessary to use technique which can give the accurate location and
size of the tumor. There are various algorithms proposed for brain tumor detection, this paper
presents a survey on the various brain tumor detection algorithms. It gives the existing techniques
and what are the advantages and disadvantages of these techniques.
Keywords–Brain tumor, MR Imaging (MRI),segmentation,K–means
I. INTRODUCTION A tumor is a mass of cell that is formed by accumulation of abnormal cells.
The complex brain tumors can be categorized on the basis of their origin, growth pattern and
malignancy. It can be detected as benign or malignant, benign being the non–cancerous and
malignant the cancerous.
The diagnosis of brain tumor is difficult because of the diversity in shape, size and location in the
brain. Medical imaging helps in the detection of tumor, there are various techniques like MRI, CT
scan, Ultrasound and X–ray. We are taking Magnetic Resonance Imaging (MRI) into consideration.
MRI gives high quality images of the body parts and is often used while treating tumors. To detect
the tumor area in the human brain, separation of cells from the nuclei is

technologies to commit serious crimes like cracking sites, fraud in different domains, prohibited
access etc. Thus, the inquiry of such cases is very difficult and more significant task. So, we need to
do the analysis of crime scene data. In digital forensic analysis time factor play very critical role. So
it's a not an easy task for investigator to do such complex analysis in very short period of time. This
is the main reason we used the digital forensic analysis of documents technique where complex task
is accomplished using a simpler approach. Such type of analysis technique includes document
clustering. So, clustering algorithms play very important role for efficient results. In this paper we
used proposed novel approach to achieve more efficient document clustering in forensic analysis.
Keywords: Document Clustering, Forensic Analysis, Investigation, Data Mining. 1. Introduction:
Recently in the world of digital technology especially in the computer world there is tremendous
increase in crime like unauthorized access, money laundering etc. So, investigation of such cases is
much more important task for that kind of crime investigation that's why we need to do digital

different clustering algorithm techniques in data mining. Clustering techniques is broadly used in
many applications such as pattern recognition, market research, image processing and data analysis.
Cluster Analysis is an excellent data mining tool for a large and multivariate database. A cluster of
data objects can be treated as one group. In clustering analysis our object is first partition the set of
data into similar data groups and then assigns labels to those groups. Clustering is a suitable
example of unsupervised classification. Keywords–Data Mining; Clustering algorithms; Techniques;

Installing A Realistic Wireless Sensor Network Setting
Abstract–Hierarchical routing is a promising approach for point–to point routing with very small
routing state. While there are many theoretical analyses and high–level simulations demonstrating
its benefits, there has been little work to evaluate it in a realistic wireless sensor network setting.
Based on numerous proposed hierarchical routing infrastructures, we surveyed some hierarchical
clustering algorithms and briefly discussed them. Main purpose of this paper is to present some
recent hierarchical protocols and point out silent features of them. These routing protocols very
much benefit in prolonging network lifetime and save energy of sensor nodes.
Keywords: hierarchical protocols, clustering, wireless sensor networks, residual ... Show more
Due to limited and non–rechargeable energy provision, the energy resource of sensor networks
should be managed wisely to extend the lifetime of sensors. Sensor networks have recently emerged
as a platform for several important surveillance and control applications .Each sensor has an
onboard radio that can be used to send the collected data to interested parties. One of the advantages
of wireless sensors networks (WSNs) is their ability to operate unattended in harsh environments in
which contemporary human–in–the–loop monitoring schemes are risky, inefficient and sometimes
infeasible. Therefore, sensors are expected to be deployed randomly in the area of interest by a
relatively uncontrolled means, e.g. dropped by a helicopter, and to collectively form a network in an
ad–hoc manner. In order to achieve high energy efficiency and increase the network scalability,
sensor nodes can be organized into clusters. Data collected from sensors are sent to the cluster head
first, and then forwarded to the base station. Network lifetime can be defined as the time elapsed
until the first node (or the last node) in the network depletes its energy (dies). A number of protocols
have been proposed to reduce useful energy consumption. These protocols can be classified into
three classes. Protocols in the first class control the transmission power level at each node to
increase network capacity while

Bootstrap Sampling In Cluster Analysis Essay
Bootstrap sampling in cluster analysis is a valuable tool that can be used in bioinformatics as well as
in other areas of research. In bioinformatics, clustering can be used in genetics studies to find
clusters of subjects according to their gene expression levels. We can then see if subjects with the
same disease state or treatment have the same gene profiles, which can give us more information
about diseases or treatments and their relations to genetics.
The Hierarchical Ordered Partitioning and Collapsing Hybrid (HOPACH) clustering algorithm can
be used to identify clusters of data. There is a package in R that corresponds to this method which is
built especially for bioinformatical data. This method works in four steps: ... Show more content on
Helpwriting.net ...
One question that was asked during the in–class discussion, but was never answered was the number
of bootstrap datasets that were used in the HOPACH method. In looking further into this, I found
that the default number of bootstrap samples is 1000. The documentation for this package noted that
this method is computationally expensive, especially as the number of bootstrap samples gets larger.
Something that I would be interested in learning more about is the extent to which the number of
bootstrap samples affects the results of the cluster validation as well as how low you can go in the
number of bootstrap samples while still ensuring a relatively high level of accuracy. Especially for
big data sets I would assume that it is important to minimize the computational time and power used
in analysis, so it would be valuable to have more information on the effects of lowering the number
of bootstrap samples both on computational expense as well as on accuracy.
I am also curious concerning other ways the HOPACH method along with bootstrapping could be
used within the field of bioinformatics. One application, which we touched on a little bit during our
discussion, might be to cluster genes rather than research subjects. I think this would only be
practical after the number of genes of interest had been minimized through other

View Point Based Similarity Measure By Clustering

Professor, Department of CSE Ganapathy Engineering College , Hunter Raod ,Warangal Abstract–
This All clustering methods have to assume some cluster relationship among the data objects that
they are applied on. Similarity between a pair of objects can be defined either explicitly or
implicitly. In this paper, we introduce a novel multi–viewpoint based similarity measure and two
related clustering methods. The major difference between a traditional dissimilarity/similarity
measure and ours is that the former uses only a single viewpoint, which is the origin, while the latter
utilizes many different viewpoints, which are objects assumed to not be in the same cluster with the
two objects being measured. Using multiple viewpoints, more informative assessment of similarity
could be achieved. Theoretical analysis and empirical study are conducted to support this claim.
Two criterion functions for document clustering are proposed based on this new measure. We
compare them with several well–known clustering algorithms that use other popular similarity
measures on various document collections to verify the advantages of our proposal. Keywords–

routing path, minimum vary of hops, and minimum trafﬁc load in terms of leveling energy

Brain tumor detection is a tedious job because of the complex structure of the brain. From the MR
images, the information such as tumor location can be understood. It provides an easier way to
diagnose the tumor and plan the surgical approach for its removal. Doctors do not have a method
that can be used for brain tumor detection and standardization, which leads to varying conclusions
between one doctor to another. There comes the requirement of an automated system for locating
tumor in Magnetic Resonance Image (MRI).
The existing classification methods have limitation in accuracy, exactness and require manual
interaction. So, designing automated system using image segmentation techniques helps make the
detection accurate and efficient.
A new system that can be used as a second decision for the surgeons and radiologists is proposed. In
this system, brain tumors have been segmented with the help of two methods that is Enhanced K–
Strange Points and K–Means algorithms followed by Morphological Filtering.

The Enhanced K–Strange Points Clustering algorithm converged faster with less number of steps
than the K–Means Clustering algorithm.
Segmentation of brain image is imperative in surgical planning and treatment planning in the field of
medicine. In this work, we have proposed a computer–aided system for brain MR image
segmentation using Enhanced K–Strange Points Clustering algorithms

Data Mining Method Of Extracting The Data From Large Database

Clustering plays an important role in data mining process. Clustering is the approach of grouping the
data into classes or clusters so that the objects within each cluster have high similarity in comparison
with one another[12].The common approach of clustering techniques is that to find cluster centroid
and then the data are clustered. Several clustering techniques are partitioning methods, hierarchical
methods, density based methods, grid based methods, model based methods and constraint based
clustering. Clustering is a challenging field of research in which its potential applications pose their
own requirements [4]. Clustering is also called as the data segmentation because clustering method
partitions the large data sets into smaller data groups according to their similarities. The main
objective of cluster analysis is to increase intra–group similarity and inter–group dissimilarity.
Detecting outlier is one of the important tasks. A failure to detect outliers or their ineffective
handling can have serious ramifications on the strength of the inferences drained from the exercise
[4]. Outlier detection has direct applications in a wide variety of domains such as mining for
anomalies to detect network intrusions, fraud detection in mobile phone industry and recently for
detecting terrorism related activities [5].Outliers are found using the filters which is offered by data
mining tools. Liver disorder is also referred to as

relationships, on the clustering performance, is not studied. Another Word–Net–based clustering
method is presented in (Fodeh et al., 2011), where the role of nouns, especially polysemous and
synonymous nouns in document clustering is investigated. A subset of core semantic features is

fifteen years. They have developed a reputation for the cheapest computer parts by focussing on a

Ultimately, P&P computers can gain a competitive advantage through understanding the desires and
needs of their loyal customer base. Furthermore, this project will also use association rules within
customer segments to predict what items are most likely to be purchased together thus informing
future business decisions. Background: Loyalty programmes have rapidly proliferated in almost all
consumer focussed industries. In the United States alone, explicit opt in programme memberships
topped 2.6 billion in 2012 (IIDA, 2014). The vast amount of transactional and demographic data
gathered from loyalty programmes has been used by many organisations to drive business decisions.
The use of supervised and unsupervised learning has been used to gather different information about
customer desires, trends and loyalty. There are two primary modelling approaches, they are recency,
frequency and monetary (RFM) model and the customer life value model (CLV). The RFM model
focusses on three key metrics; how recently a customer has purchased, how often they purchase and
how much money they spend. On the other hand, the CLV model attempts to predict the amount of
money a customer will spend with the company from present day till the time the business
relationship is terminated. Gupta et al (2006) indicate that the main limitation to RFM models is that
they use a scoring system and do not provide a specific dollar value. However, there are successful
cases where an RFM model was

Abstract– There are different types of tumors are available. Astrocytoma is the most common type
of tumor (30% of all brain tumor) and is usually a malignant one. Astrocytoma can be subdivided
into four grades. Each grade has its own characteristics and unique treatment. In the event that any
wrong treatment is given to these evaluations that prompts passing. So finding the position and
shape of tumor is very important for the further treatment. The proposed system of this paper is to
find the exact position and shape of the tumor cells. That helps the physician for further treatment.
In the proposed system, it consists of four modules (i) Pre–processing, (ii) Segmentation of brain in
MR Images,(iii) Quality extraction and (iv) Inexact reasoning. Preprocessing is carried out by
sifting. Segmentation is carried out by cutting edge both K–means and Fuzzy C–means calculations.
Quality extraction is by thresholding. Finally, Approximate reasoning method to recognize the tumor
shape and position in MRI image. If the tumor is a mass in shape then k–means algorithm is enough
to extract it from brain cells. Suppose if it is a malignant (spread over the brain) one then the Fuzzy
C–means algorithm

Distance Between Clusters And Nearest Neighbor
Distance between clusters
Nearest neighbor (single linkage). In this measure the similarity between two clusters is defined as
the smallest distance between two objects in different clusters. Distance between cluster A and
cluster B is the minimum amongst the following pairs (1,5), (1,6), (1,7), (2,5), (2,6), and (2,7). In
each iteration, the distance between two different clusters is equal to the distance between its closest
members.
Furthest neighbor (complete linkage). With this similarity measure, the distance between two
different clusters is equal to the maximum amongst all pairs. It is equal to the distance amongst their
members who are the farthest.
UPGMA Using the average linkage method, called UPGMA, the distance between two different
clusters is equal to the average of the distance of all their pairs. This method is usually preferred
over nearest neighbor or farthest neighbor because it encompasses the knowledge of all pairs instead
of focusing on one single pair.
Average linkage within groups. UPGMA considers average of all pairs. The average linkage method
combines clusters in such a way that the average distance in the resulting cluster from all the pairs is
as small as possible.This method is particularly useful when it is computationally expensive to
calculate distances between all pairs.
Ward's method. In each cluster the means for each variable is computed. Then the Euclidean
distance of each member from this means is calculated. These

CLUSTERING TECHNIQUES
Clustering or Cluster analysis is defined as the process of organizing objects into groups whose
members are similar in some way. Therefore, a cluster is the collection of objects which are similar
to each other and are dissimilar to the objects belonging to other clusters. The objects in one cluster
are more related and have high similarity when compared to the objects that are in other cluster. So,
we can also define clustering as "The process of grouping a set of data objects into clusters or
various groups so that the objects within the clusters have high similarity, but very dissimilar to
objects that are in other clusters". Based on the attribute values that interpret the objects and distance

In the case of Image Recognition the concept of clustering can be applied to identify the clusters in
handwritten character recognition systems. Many applications of clustering are also found in Web
search. Clustering can be utilized to organize the query results in groups and present the outcomes in
a concise and effectively available way. We can distinguish and sparse regions in object space by
automated clustering and from that we can find general interesting correlations and overall
distribution patterns among data attributes. Cluster analysis has been broadly utilized as a part of
various applications, like market research, pattern recognition, data analysis, and image processing.
In business, clustering can offer marketers some assistance with discovering distinct groups in their
client bases and portray client groups taking into account the purchasing patterns. In science, it can
be utilized to determine plant and animal scientific categorizations, order qualities with similar
functionality, and addition knowledge into structures inborn in populations. For the identification of
the same land use in the earth observation database we use clustering. It can also be used for finding
groups of houses in a city based on the house type, value and the geographic location. It will be
helpful in identifying the groups of the policy holders with the highest average claim cost of the
automobile insurance.
