A CONCEPTUAL METADATA FRAMEWORK FOR SPATIAL DATA WAREHOUSEIJDKP
Metadata represents the information about data to be stored in Data Warehouses. It is a mandatory
element of Data Warehouse to build an efficient Data Warehouse. Metadata helps in data integration,
lineage, data quality and populating transformed data into data warehouse. Spatial data warehouses are
based on spatial data mostly collected from Geographical Information Systems (GIS) and the transactional
systems that are specific to an application or enterprise. Metadata design and deployment is the most
critical phase in building of data warehouse where it is mandatory to bring the spatial information and
data modeling together. In this paper, we present a holistic metadata framework that drives metadata
creation for spatial data warehouse. Theoretically, the proposed metadata framework improves the
efficiency of accessing of data in response to frequent queries on SDWs. In other words, the proposed
framework decreases the response time of the query and accurate information is fetched from Data
Warehouse including the spatial information

Study and Analysis of K-Means Clustering Algorithm Using RapidminerIJERA Editor
Institution is a place where teacher explains and student just understands and learns the lesson. Every student has his own definition for toughness and easiness and there isn’t any absolute scale for measuring knowledge but examination score indicate the performance of student. In this case study, knowledge of data mining is combined with educational strategies to improve students’ performance. Generally, data mining (sometimes called data or knowledge discovery) is the process of analysing data from different perspectives and summarizing it into useful information. Data mining software is one of a number of analytical tools for data. It allows users to analyse 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 database. Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters).This project describes the use of clustering data mining technique to improve the efficiency of academic performance in the educational institutions .In this project, a live experiment was conducted on students .By conducting an exam on students of computer science major using MOODLE(LMS) and analysing that data generated using RapidMiner(Datamining Software) and later by performing clustering on the data. This method helps to identify the students who need special advising or counselling by the teacher to give high quality of education.
A MIXTURE MODEL OF HUBNESS AND PCA FOR DETECTION OF PROJECTED OUTLIERSZac Darcy
With the Advancement of time and technology, Outlier Mining methodologies help to sift through the large
amount of interesting data patterns and winnows the malicious data entering in any field of concern. It has
become indispensible to build not only a robust and a generalised model for anomaly detection but also to
dress the same model with extra features like utmost accuracy and precision. Although the K-means
algorithm is one of the most popular, unsupervised, unique and the easiest clustering algorithm, yet it can
be used to dovetail PCA with hubness and the robust model formed from Guassian Mixture to build a very
generalised and a robust anomaly detection system. A major loophole of the K-means algorithm is its
constant attempt to find the local minima and result in a cluster that leads to ambiguity. In this paper, an
attempt has done to combine K-means algorithm with PCA technique that results in the formation of more
closely centred clusters that work more accurately with K-means algorithm
USING ONTOLOGIES TO IMPROVE DOCUMENT CLASSIFICATION WITH TRANSDUCTIVE SUPPORT...IJDKP
Many applications of automatic document classification require learning accurately with little training
data. The semi-supervised classification technique uses labeled and unlabeled data for training. This
technique has shown to be effective in some cases; however, the use of unlabeled data is not always
beneficial.
On the other hand, the emergence of web technologies has originated the collaborative development of
ontologies. In this paper, we propose the use of ontologies in order to improve the accuracy and efficiency
of the semi-supervised document classification.
We used support vector machines, which is one of the most effective algorithms that have been studied for
text. Our algorithm enhances the performance of transductive support vector machines through the use of
ontologies. We report experimental results applying our algorithm to three different datasets. Our
experiments show an increment of accuracy of 4% on average and up to 20%, in comparison with the
traditional semi-supervised model.
Clustering technology has been applied in numerous applications. It can enhance the performance
of information retrieval systems, it can also group Internet users to help improve the click-through rate of
on-line advertising, etc. Over the past few decades, a great many data clustering algorithms have been
developed, including K-Means, DBSCAN, Bi-Clustering and Spectral clustering, etc. In recent years, two
new data clustering algorithms have been proposed, which are affinity propagation (AP, 2007) and density
peak based clustering (DP, 2014). In this work, we empirically compare the performance of these two latest
data clustering algorithms with state-of-the-art, using 6 external and 2 internal clustering validation metrics.
Our experimental results on 16 public datasets show that, the two latest clustering algorithms, AP and DP,
do not always outperform DBSCAN. Therefore, to find the best clustering algorithm for a specific dataset, all
of AP, DP and DBSCAN should be considered. Moreover, we find that the comparison of different clustering
algorithms is closely related to the clustering evaluation metrics adopted. For instance, when using the
Silhouette clustering validation metric, the overall performance of K-Means is as good as AP and DP. This
work has important reference values for researchers and engineers who need to select appropriate clustering
algorithms for their specific applications.
Clustering the results of a search helps the user to overview the information returned. In this paper, we
look upon the clustering task as cataloguing the search results. By catalogue we mean a structured label
list that can help the user to realize the labels and search results. Labelling Cluster is crucial because
meaningless or confusing labels may mislead users to check wrong clusters for the query and lose extra
time. Additionally, labels should reflect the contents of documents within the cluster accurately. To be able
to label clusters effectively, a new cluster labelling method is introduced. More emphasis was given to
/produce comprehensible and accurate cluster labels in addition to the discovery of document clusters. We
also present a new metric that employs to assess the success of cluster labelling. We adopt a comparative
evaluation strategy to derive the relative performance of the proposed method with respect to the two
prominent search result clustering methods: Suffix Tree Clustering and Lingo.
we perform the experiments using the publicly available Datasets Ambient and ODP-239
Deep Convolutional Neural Network based Intrusion Detection SystemSri Ram
In the present era, the cyberspace is growing tremendously and Intrusion detection system (IDS) plays an key role in it to ensure the information security. The IDS, which works in network and host level, should be capable of identifying various malicious attacks. The job of network based IDS is to differentiate between normal and malicious traffic data and raise alert in case of an attack. Apart from the traditional signature and anomaly based approaches, many researchers have employed various Deep Learning (DL) techniques for detecting intrusion as DL models are capable of extracting salient features automatically from the input data. The application of Deep Convolutional Neural Network (DCNN), which is utilized quite often for solving research problems in image processing and vision fields, is not explored much for IDS. In this paper, a DCNN architecture for IDS which is trained on KDDCUP 99 data set is proposed. This work also shows that the DCNN-IDS model performs superior when compared with other existing works.
Optimisation towards Latent Dirichlet Allocation: Its Topic Number and Collap...IJECEIAES
Latent Dirichlet Allocation (LDA) is a probability model for grouping hidden topics in documents by the number of predefined topics. If conducted incorrectly, determining the amount of K topics will result in limited word correlation with topics. Too large or too small number of K topics causes inaccuracies in grouping topics in the formation of training models. This study aims to determine the optimal number of corpus topics in the LDA method using the maximum likelihood and Minimum Description Length (MDL) approach. The experimental process uses Indonesian news articles with the number of documents at 25, 50, 90, and 600; in each document, the numbers of words are 3898, 7760, 13005, and 4365. The results show that the maximum likelihood and MDL approach result in the same number of optimal topics. The optimal number of topics is influenced by alpha and beta parameters. In addition, the number of documents does not affect the computation times but the number of words does. Computational times for each of those datasets are 2.9721, 6.49637, 13.2967, and 3.7152 seconds. The optimisation model has resulted in many LDA topics as a classification model. This experiment shows that the highest average accuracy is 61% with alpha 0.1 and beta 0.001.
An Iterative Improved k-means ClusteringIDES Editor
Clustering is a data mining (machine learning),
unsupervised learning technique used to place data elements
into related groups without advance knowledge of the group
definitions. One of the most popular and widely studied
clustering methods that minimize the clustering error for
points in Euclidean space is called K-means clustering.
However, the k-means method converges to one of many local
minima, and it is known that the final results depend on the
initial starting points (means). In this research paper, we have
introduced and tested an improved algorithm to start the kmeans
with good starting points (means). The good initial
starting points allow k-means to converge to a better local
minimum; also the numbers of iteration over the full dataset
are being decreased. Experimental results show that initial
starting points lead to good solution reducing the number of
iterations to form a cluster.
Mining academic social network is becoming increasingly necessary with the increasing amount of data. It

academic social networks. In this paper, we are presenting an efficient frequent item set mining technique
for social academic network. The proposed framework first processes the research documents and then the
enhanced frequent item set mining is applied to find the strength of relationship between the researchers.
The proposed method will be fast in comparison to older algorithms. Also it will takes less main memory
space for computation purpose.
sis of health condition is very challenging task for every human being because life is directly related to health

research work, we have used various classification techniques for classification of thyroid data. CART gives highest
accuracy 99.47% as best model. Feature selection plays very important role to computationally efficient and increase
the performance of model. This research work focus on Info Gain and Gain Ratio feature selection technique to
reduce the irrelevant features from original data set and computationally increase the performance of model. We have
applied both the feature selection techniques on best model i. e. CART. Our proposed CART-Info Gain and CARTGain
Ratio gives 99.47% and 99.20% accuracy with 25 and 3 feature respectively.
New proximity estimate for incremental update of non uniformly distributed cl...IJDKP
The conventional clustering algorithms mine static databases and generate a set of patterns in the form of
clusters. Many real life databases keep growing incrementally. For such dynamic databases, the patterns
extracted from the original database become obsolete. Thus the conventional clustering algorithms are not
suitable for incremental databases due to lack of capability to modify the clustering results in accordance
with recent updates. In this paper, the author proposes a new incremental clustering algorithm called
CFICA(Cluster Feature-Based Incremental Clustering Approach for numerical data) to handle numerical
data and suggests a new proximity metric called Inverse Proximity Estimate (IPE) which considers the
proximity of a data point to a cluster representative as well as its proximity to a farthest point in its vicinity.
CFICA makes use of the proposed proximity metric to determine the membership of a data point into a
cluster.
CLASSIFIER SELECTION MODELS FOR INTRUSION DETECTION SYSTEM (IDS)ieijjournal1
Any abnormal activity can be assumed to be anomalies intrusion. In the literature several techniques and
algorithms have been discussed for anomaly detection. In the most of cases true positive and false positive
parameters have been used to compare their performance. However, depending upon the application a
wrong true positive or wrong false positive may have severe detrimental effects. This necessitates inclusion
of cost sensitive parameters in the performance. Moreover the most common testing dataset KDD-CUP-99
has huge size of data which intern require certain amount of pre-processing. Our work in this paper starts
with enumerating the necessity of cost sensitive analysis with some real life examples. After discussing
KDD-CUP-99 an approach is proposed for feature elimination and then features selection to reduce the
number of more relevant features directly and size of KDD-CUP-99 indirectly. From the reported
literature general methods for anomaly detection are selected which perform best for different types of
attacks. These different classifiers are clubbed to form an ensemble. A cost opportunistic technique is
suggested to allocate the relative weights to classifiers ensemble for generating the final result. The cost
sensitivity of true positive and false positive results is done and a method is proposed to select the elements
of cost sensitivity metrics for further improving the results to achieve the overall better performance. The
impact on performance trade of due to incorporating the cost sensitivity is discussed.

Anonymization of data using mapreduce on cloudeSAT Journals
Abstract In computer world cloud services are provided by the service providers. The user wants to share the private data which are stored in cloud server for different reasons like data mining, data analysis etc. These can bring the privacy concern. Privacy preservation can be satisfied by Anonymizing data sets through generalization to satisfy privacy requirements by using k-anonymity technique which is a widely used type of privacy preserving techniques. At present days the data of cloud applications are increasing their scale day by day concern with Big Data trend. So it is very difficult thing to accept, manage, maintain and process the large scaled data with-in the required time stamps. Thus for privacy preserving on privacy sensitive , large scaled data is very difficult task for existing anonymization techniques because they will not manage the scaled data sets. This approach addresses the anonymization problem on large scale cloud data sets using two phase top down specialization approach and MapReduce framework. Innovative MapReduce jobs are carefully designed in both phases of this technique to achieve specialization computation on scalable data sets. Scalability and efficiency of Top Down Specialization (TDS) is significantly increased over the existing approach.

The Use of K-NN and Bees Algorithm for Big Data Intrusion Detection SystemIOSRjournaljce
Big data problem in intrusion detection system is mainly due to the large volume of the data. The dimension of the original data is 41. Some of the feature of original data are unnecessary. In this process, the volume of data has expanded into hundreds and thousands of gigabytes(GB) of information. The dimension span of data and volume can be reduced and the system is enhanced by using K-NN and BA. The reduction ratio of KDD datasets and processing speed is very slow so the data has been reduced for extracting features by Bees Algorithm (AB) and use K-nearest neighbors as classification (KNN). So, the KDD99 datasets applied in the experiments with significant features. The results have gave higher detection and accuracy rate as well as reduced false positive rate. Keywords: Big Data; Intru

Perfomance Comparison of Decsion Tree Algorithms to Findout the Reason for St...ijcnes
Educational data mining is used to study the data available in the educational field and bring out the hidden knowledge from it. Classification methods like decision trees, rule mining can be applied on the educational data for predicting the students behavior. This paper focuses on finding thesuitablealgorithm which yields the best result to find out the reason behind students absenteeism in an academic year. The first step in this processis to gather students data by using questionnaire.The datais collected from 123 under graduate students from a private college which is situated in a semirural area. The second step is to clean the data which is appropriate for mining purpose and choose the relevant attributes. In the final step, three different Decision tree induction algorithms namely, ID3(Iterative Dichotomiser), C4.5 and CART(Classification and Regression Tree)were applied for comparison of results for the same data sample collected using questionnaire. The results were compared to find the algorithm which yields the best result in predicting the reason for student s absenteeism.
Data Preparation and Reduction Technique in Intrusion Detection Systems: ANOV...CSCJournals
Intrusion detection system plays a main role in detecting anomaly and suspected behaviors in many organization environments. The detection process involves collecting and analyzing real traffic data which in heavy-loaded networks represents the most challenging aspect in designing efficient IDS.
Collected data should be prepared and reduced to enhance the classification accuracy and computation performance.
In this research, a proposed technique called, ANOVA-PCA, is applied on NSL-KDD dataset of 41 features which are reduced to 10. It is tested and evaluated with three types of supervised classifiers: k-nearest neighbor, decision tree, and random forest. Results are obtained using various performance measures, and they are compared with other feature selection algorithms such as neighbor component analysis (NCA) and ReliefF. Results showed that the proposed method was simple, faster in computation compared with others, and good classification accuracy of 98.9% was achieved.
Data imputing uses to posit missing data values, as missing data have a negative effect on the computation validity of models. This study develops a genetic algorithm (GA) to optimize imputing for missing cost data of fans used in road tunnels by the Swedish Transport Administration (Trafikverket). GA uses to impute the missing cost data using an optimized valid data period. The results show highly correlated data (R- squared 0.99) after imputing the missing data. Therefore, GA provides a wide search space to optimize imputing and create complete data. The complete data can be used for forecasting and life cycle cost analysis.

Predictive Data Mining with Normalized Adaptive Training Method for Neural Ne...IJERDJOURNAL
Abstract:- Predictive data mining is an upcoming and fast-growing field and offers a competitive edge for the benefit of organization. In recent decades, researchers have developed new techniques and intelligent algorithms for predictive data mining. In this research paper, we have proposed a novel training algorithm for optimizing neural networks for prediction purpose and to utilize it for the development of prediction models. Models developed in MATLAB Neural Network Toolbox have been tested for insurance datasets taken from a live data warehouse. A comparative study of the proposed algorithm with other popular first and second order algorithms has been presented to judge the predictive accuracy of the suggested technique. Various graphs have been presented to analyse the convergence behaviour of different algorithms towards point of minimum error.
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
