This document summarizes a research paper on using k-means clustering to analyze big data. It begins with an introduction to big data and its characteristics. It then discusses related work on big data storage, mining, and analytics. The HACE theorem for defining big data is presented. The k-means clustering algorithm is explained as an efficient method for partitioning big data into groups. The proposed system uses k-means clustering followed by data mining and classification modules. Experimental results on two datasets show that the recursive k-means approach finds clusters closer to the actual number than the iterative approach. In conclusion, clustering is effective for handling big data attributes like heterogeneity and complexity, and k-means distribution helps distribute data into appropriate clusters.
An Efficient Approach for Clustering High Dimensional DataIJSTA
The document discusses clustering high dimensional data using an efficient approach called "Big Data Clustering using k-Mediods BAT Algorithm" (KMBAT). KMBAT simultaneously considers all data points as potential exemplars and exchanges real-valued messages between data points until a high-quality set of exemplars and corresponding clusters emerges. It is demonstrated on Facebook user profile data stored in an HDInsight Hadoop cluster. KMBAT finds better clustering solutions than other methods in less time for high dimensional big data.

Big data is a prominent term which characterizes the improvement and availability of data in all three
formats like structure, unstructured and semi formats. Structure data is located in a fixed field of a record
or file and it is present in the relational data bases and spreadsheets whereas an unstructured data file
includes text and multimedia contents. The primary objective of this big data concept is to describe the
extreme volume of data sets i.e. both structured and unstructured. It is further defined with three “V”
dimensions namely Volume, Velocity and Variety, and two more “V” also added i.e. Value and Veracity.
Volume denotes the size of data, Velocity depends upon the speed of the data processing, Variety is
described with the types of the data, Value which derives the business value and Veracity describes about
the quality of the data and data understandability. Nowadays, big data has become unique and preferred
research areas in the field of computer science. Many open research problems are available in big data
and good solutions also been proposed by the researchers even though there is a need for development of
many new techniques and algorithms for big data analysis in order to get optimal solutions. In this paper,

Misusability Measure Based Sanitization of Big Data for Privacy Preserving Ma...IJECEIAES
Leakage and misuse of sensitive data is a challenging problem to enterprises. It has become more serious problem with the advent of cloud and big data. The rationale behind this is the increase in outsourcing of data to public cloud and publishing data for wider visibility. Therefore Privacy Preserving Data Publishing (PPDP), Privacy Preserving Data Mining (PPDM) and Privacy Preserving Distributed Data Mining (PPDM) are crucial in the contemporary era. PPDP and PPDM can protect privacy at data and process levels respectively. Therefore, with big data privacy to data became indispensable due to the fact that data is stored and processed in semi-trusted environment. In this paper we proposed a comprehensive methodology for effective sanitization of data based on misusability measure for preserving privacy to get rid of data leakage and misuse. We followed a hybrid approach that caters to the needs of privacy preserving MapReduce programming. We proposed an algorithm known as Misusability Measure-Based Privacy Preserving Algorithm (MMPP) which considers level of misusability prior to choosing and application of appropriate sanitization on big data. Our empirical study with Amazon EC2 and EMR revealed that the proposed methodology is useful in realizing privacy preserving Map Reduce programming.

A Survey of Agent Based Pre-Processing and Knowledge RetrievalIOSR Journals
Abstract: Information retrieval is the major task in present scenario as quantum of data is increasing with a
tremendous speed. So, to manage & mine knowledge for different users as per their interest, is the goal of every
organization whether it is related to grid computing, business intelligence, distributed databases or any other.
To achieve this goal of extracting quality information from large databases, software agents have proved to be
a strong pillar. Over the decades, researchers have implemented the concept of multi agents to get the process
of data mining done by focusing on its various steps. Among which data pre-processing is found to be the most
sensitive and crucial step as the quality of knowledge to be retrieved is totally dependent on the quality of raw
data. Many methods or tools are available to pre-process the data in an automated fashion using intelligent
(self learning) mobile agents effectively in distributed as well as centralized databases but various quality
factors are still to get attention to improve the retrieved knowledge quality. This article will provide a review of
the integration of these two emerging fields of software agents and knowledge retrieval process with the focus
on data pre-processing step.

This document proposes an improved steganography approach using color-guided channels in digital images. It begins with an introduction to steganography and discusses how it can be used to hide secret data or messages within cover objects like images, video, or audio files. The proposed method embeds data into a color image's RGB channels. It first converts the secret message to a binary bit stream and compresses it using run length encoding. The data is then embedded directly into the LSBs of some channels and indirectly into other channels by encoding counts. This approach aims to improve the visual quality of the stego image and have higher embedding capacity compared to existing methods.

Certain Investigation on Dynamic Clustering in Dynamic Dataminingijdmtaiir
Clustering is the process of grouping a set of objects
into classes of similar objects. Dynamic clustering comes in a
new research area that is concerned about dataset with dynamic
aspects. It requires updates of the clusters whenever new data
records are added to the dataset and may result in a change of
clustering over time. When there is a continuous update and
huge amount of dynamic data, rescan the database is not
possible in static data mining. But this is possible in Dynamic
data mining process. This dynamic data mining occurs when
the derived information is present for the purpose of analysis
and the environment is dynamic, i.e. many updates occur.
Since this has now been established by most researchers and
they will move into solving some of the problems and the
research is to concentrate on solving the problem of using data
mining dynamic databases. This paper gives some
investigation of existing work done in some papers related with
dynamic clustering and incremental data clustering

The document proposes an improved model for big data analytics using dynamic multi-swarm optimization and unsupervised learning algorithms. It develops an algorithm called DynamicK-reference Clustering that combines dynamic multi-swarm optimization with a k-reference clustering algorithm. The k-reference clustering algorithm uses reference distance weighting, Euclidean distance, and chi-square relative frequency to cluster mixed datasets. It was tested on several datasets from a machine learning repository and was shown to more efficiently cluster large, mixed datasets than other clustering algorithms like k-means and particle swarm optimization. The dynamic multi-swarm optimization helps guide the clustering algorithm to obtain more accurate cluster formations by providing the best initial value of k clusters.

1. INTRODUCTION
Big Data defines to datasets whose sizes (large in volume) are beyond the ability of typical database
software tools to capture, store, manage and analyze. There is no predefined definition of how big a dataset should
be in order to be considered Big Data. New technological tools have to be in place to manage and process this Big
Data phenomenon. Now a day’s Big Data technologies as a new generation of technologies and architectures
designed to extract value or pattern economically from very large volumes of a wide variety of data by enabling high
velocity capture, discovery and analysis. Big data is data that exceeds the processing capacity of traditional database
systems. The data is too big, moves too fast, or does not fit the structures of existing database architectures. To gain
value from these data, there must be an alternative way to process it.
1.1 Characteristics of Big Data-

Basically there are three main attributes of big data are as Volume, Varity and Velocity. Since volume
defines a large and huge data that cannot handle within a specified time parameter. Varity defines the difference in
structure and data types of data, due to this complex structure have evolved. Velocity shows the speeds of coming
data get increased according to time since data size changes as time get change.
2. LITERATURE SURVEY
The studies of past historical concerns are necessary to acquire the detail knowledge about topic. Since here
is the discussion about few of the papers has been carried out to define different views of author related to big data
and its mining to extract useful pattern from it.
Yang Song defines the concept of storage mining that meets the data analytics in this cloud based data
center infrastructures imposes remarkable challenges to IT management operations, e.g., due to virtualization
techniques and more stringent requirements for cost and efficiency. They was defined the Information Lifecycle
Management (ILM) with Storage Tiering that reduces the cost solution that focuses on moving less accessed storage
volumes (e.g., virtual disks in storage virtualization ) to low-end storage devices in order to free up space on high-
end devices with superb performance, e.g., good results within specified time. They had defined there are two main
challenges for big data mining as big data storage and scalable machine learning. The defined scalable machine
learning framework uses Hadoop & Cassandra cluster to implement predictive analytics.
Shuliang Wang et all Spatial Data Mining in the Context of Big Data in that they had explained Spatial data
plays a primary role in big data, attracting human interests. Spatial data mining confronts much difficulty when
attracting the value hidden in spatial big data. The techniques to discover knowledge from spatial big data may help
data to become intelligent. Spatial data is closely related to human daily life, permeated all walks of life. The
number, size and complexity are all in sharp increasing. A large amount of data has been stored in the spatial
database and warehouse in types of text, graphics, images and multimedia. Big data is voluminous and it grows
quickly, but it has very low density in value, which means there is a lot of junk data. Big data processing is to
implement the transitions: from data to information, from information to knowledge and from knowledge to
wisdom. Big data processing includes object superposition, target buffer, spatial data cleaning, spatial data analysis,
spatial data mining, spatial feature extraction, image segmentation, and image classification.
Hui Chen et all explained the concept of Parallel Mining Frequent Patterns over Big Transactional Data in
Extended MapReduce. They had explained the extended mapreduce framework in that a parallel algorithm is
presented for mining the frequent patterns in a big transactional data. According to MapReduce frame, the big data
is firstly split into a lot of data subfiles, and the subfiles are concurrently processed by a cluster consisting of
hundreds or thousands computers. In order to improve the performance of proposed method, the insignificant
patterns in the data subfile are efficiently located and pruned by probability analysis. The simulation result proves
that the method is efficient and scalable, and can be used to efficiently mine frequent patterns in big data.
Xindong Wu et all was defines a three tier big data processing framework. The research challenges form a
three tier structure and center around the “Big Data mining platform”(Tier I), which focuses on low-level data
accessing and computing. Challenges on information sharing and privacy, and Big Data application domains and
knowledge form Tier II, which concentrates on high-level semantics, application domain knowledge, and user
privacy issues. The outmost circle shows Tier III challenges on actual mining algorithms.
3. HACE THEOREM
3. Vol-1 Issue- 2 2015 IJARIIE-ISSN(O)-2395-4396
1184 www.ijariie.com 338
The HACE theorem defines an efficient way to handle the big data by considering it attributes. HACE
Theorem Statement defined as Big Data starts with large-volume, heterogeneous, autonomous sources with
distributed and decentralized control, and seeks to explore complex and evolving relationships among data.
These characteristics make it a major challenge for discovering useful knowledge from the Big Data. The
fundamental characteristic of the Big Data is the huge volume of data represented by heterogeneous and diverse
dimensionalities. This is because different information collectors prefer their own schemata or protocols for data
recording, and the nature of different applications also results in diverse data representations. An autonomous data
source with distributed controls is one of characteristic of Big Data applications. Being autonomous, each data
source is able to generate and collect information without involving (or relying on) any centralized control. While the
volume of the Big Data increases, so do the complexity and the relationships underneath the data. In an early stage of data
information systems, the concentrating on finding best feature values to represent each observation. As the data comes
from various autonomous sources followed by their own schemata defines a new level of complexity that cannot be easily
track out and doesn’t show any information. Since evolving relationships are get enhanced and affect on entire process of
mining big data.
By considering the challenges evolved due to these characteristics of big data can be easily achieved since define
a solution in such a way that a heterogeneity, decentralized control and complex and newly evolving relationships are get
handled easily. To mine big data properly means accurate and within approximated time, the handling of data by
considering these attribute gives better results.
The HACE equation for big data is
Big Data = Heterogeneous + Autonomous sources with distributed and decentralized control + Complex +
Evolving Relationships.
4. K-MEANS ALGORITHM
The clustering is a good way to classify and define data according to its similarity and dissimilarity. There are
various methods of clustering basically here the method of partitioning has used. The K-means is a one of partitioning
algorithm in which partitioning of objects has done, which is depends on the factor of similarity that means clusters are
formed in such a way that objects in the same cluster having high similarity but dissimilar to objects in other cluster.
K-Means is one of the simplest algorithm used for clustering. K-means partitions “n” observations/objects
into k clusters in which each observation/object belongs to the one cluster having similar attributes but dissimilar to
object in other cluster.
a. Algorithm K-Means-
Input:
k: the number of clusters,
D: a data set containing n objects.
Output:
A group or set of k clusters.
Method:
1) Arbitrarily choose k objects from D as the initial centers;
2) repeat

3) assign/reassign each object to the cluster to which the object is the most similar, based on the mean value of the
objects in the cluster;
4) update the cluster means, that is calculate the mean value of the objects for each cluster;

In this category of clustering the k-means is the simplest and easy method to cluster the data. The similarity
measurement for this method is carried out by distance measurement. It is most common to calculate the
dissimilarity between two patterns using a distance measure define on the feature space. The most popular metric for
distance measurement is Euclidean distance.

similar objects should be enclosed in a one cluster. In second stage data mining trends applied to mine data
efficiently from the existing clustered data set.
In this system there are two classification trends has set such as heterogeneity and homogeneity. Firstly
heterogeneity classification has been carried out since the difference in structure and attributes of objects defined.
Then in next step homogeneity factor and classification done to define similarity within the objects. Finally the
calculation of fitness factor has calculated since define or put exact or most similar data set as output according to
user request that comes from various clusters. In proposed system to build a stream-based Big Data analytic
framework for fast response and real-time decision making. The key challenges and research issues includes a
designing Big Data sampling mechanisms to reduce Big Data volumes to a manageable size for processing and
building prediction models from Big Data streams.

6. RECURSIVE findK() FUNCTION
Searching is the process of looking for a particular value in a collection. For example, a program that
maintains the membership list for a club might need to look up the information about a particular member. This
involves some form of search process. A explanation of something that refers to itself is called a recursive
definition. At first glance it looks like the function expects an initial standard deviation; but in fact, it is used such
that on the first run, that parameter is initialized to -1. Therefore, it will calculate the initial standard deviation based
on the entire sample. Within it there is a variable, tolerance, which is used to indicate how close the smaller samples
standard deviation should be to the last standard deviation to continue splitting the sample. This value is chosen
arbitrarily, and it is likely the experiment results could have been better had attempted to let the program "learn" a
good value to use.

7. DATA SETS AND RESULTS
Presented here in tabular form are the results of 20 experimental runs. More were done, of course, but due
to space requirements, only 20 are presented. In both sets, the number of samples was uniformly random between 5
and 12, the size of each sample varied from 50 to 100, and the mean and standard deviation of each sample spanned
0-100 and 0-5, respectively. In the first set of ten runs, the standard deviations of the initial samples were allowed to
vary. The second set used a fixed standard deviation of two.
Set 1: Variable Standard Deviation
Run: 1 2 3 4 5 6 7 8 9 10
k: 6 7 11 6 11 6 10 7 7 8
Iterative: 3 11 2 7 8 8 6 3 22 6
Recursive: 8 8 9 8 9 8 8 8 8 8
As the data show, neither algorithm was particularly successful at correctly finding k. The recursive
algorithm is a lot less erratic, and seems to be closer to finding k than its iterative counterpart. It should be noted,
however, that in several of the cases where the recursive algorithm found too few clusters, particularly when it was

one or two off, looking at the individual generated clusters reveals that actually, it was very good - just that two or
three of the means were incredibly close, and the algorithm could not differentiate between all the sets. For
example, in the first run of the fixed standard deviation, one of the means was 87.68 with another at 89.78. In this
case, it is unlikely even a human could have differentiated between the two. Similarly, in the sixth run of the same
set, two of the generated means were less than a standard deviation apart. However, a glaring issue with the
recursive trials is that it appears to always hover around eight or nine indicating that perhaps the tolerance was so
low, it encouraged splitting the sample all the time. However, even varying the side of the equation in which the
tolerance was applied (or subtracting it instead of adding it) did not change the variety of results obtained.
8. CONCLUSIONS
A big data can be handled effectively by using clustering approach and concentrating on attributes of big
data such as Heterogeneity and evolves complex relationship. Here the use of iterative k means defines the exact
clustering method which helps to distribute data. A classification of big data carried out in such a way that objects in
the one cluster are having similarity but objects in other clusters are dissimilar to same. Whenever user want to
retrieve a data by considering several attributes can possible with the help of defined approach.
