The ability of data mining to provide predictive information
derived from huge databases became an effective tool in the hands
of companies and individuals، allowing them to focus on areas that
are important to them from the massive data generated
by the
march of their daily lives. Along with the increasing importance of
this science there was a rapidly increasing in the tools that produced
to implement the theory concepts as fast as possible. So it will be
hard to take a decision on which of these tools is the best to
perform the desired task. This study provides a comparison
between the two most commonly used data mining tools according
to opinion polls، namely: Rapidminer and R programming language
in order to help researchers and developers to choose the best suited
tool for them between the two. Adopted the comparison on seven
criteria: platform، algorithms، input/output formats، visualization،
user’s evaluation، infrastructure and potential development، and
performance by applying a set of classification algorithms on a
number of data sets and using two techniques to split data set: cross
validation and hold-out to make sure of the results. The Results
show that R supports the largest number of algorithms، input/output
formats، and visualization. While Rapidminer superiority in terms
of ease of use and support for a greater number of platforms. In
terms of performance the accuracy of classification models that
were built using the R packages were higher. That was not true in
some cases imposed by the nature of the data because we did not
added any pre-processing stage. Finally the preference option in
any tool is depending on the extent of the user experience and
purpose that the tool is used for
In this paper we introduce a comparison for some of data mining algorithm for traffic accidents analysis.
We start by describing available data for entry by analyzing the structure of statistical reports in Lattakia traffic directorate, and proceed
to data mining stage which enables us to smart study of factors that play roles in traffic accident and find its inter-relations and importance for causing traffic accident.
That comes after building data warehouse upon the database we built to store the data we gathered.
In this research we list a some of models was tested which is a sample of a many cases we checked to have the research results.
Association Rules is an important field in Data Mining, which is
used to discover useful knowledge from a massive databases.
Association Rules have been used to extract the information from
the database transactions, and Apriori Algorithm is a pra
ctical
application for Association Rules and it is used to find frequent
itemsets from database transactions. In this paper, we present a
new improving on Apriori Algorithm by reduction generating of
candidate itemsets and this leads to improving efficiency Apriori
Algorithm.
In this research, we offered a new and simple way of
Handwriting Characters Recognition. This way extracts positions of
the black points from binary images (black, white) according to
certain coordinates which are used in the stages of training an
d
testing. The extracted positions are stored in a database according
to appropriate structure for predictive data mining.
We used training data to build a predictive model which helps
in Recognition testing data depending on the data stored in the
database. We have conducted a number of tests on different
samples of handwriting character images. We got accurate results,
within the required conditions.
The main goal of data mining process is to extract information and
discover knowledge from huge databases, where the clustering is
one of the most important functionalities which can be done in this
area. There are many of clustering algorithms an
d methods, but
determining or estimating the number of clusters which should be
extracted from a dataset is one of the most important issues most of
these methods encounter it. This research focuses on the problem of
estimating number of clusters in the case of agglomerative
hierarchical clustering. We present an evaluation of three of the
most common methods used in estimating number of clusters.
The objective of this paper is presenting an educational data
mining case study, by applying data mining techniques.
