ABSTRACT
According to the increase of using data mining techniques in improving educational systems
operations, Educational Data Mining has been introduced as a new and fast growing research
area. Educational Data Mining aims to analyze data in educational environments in order to
solve educational research problems. In this paper a new associative classification technique
has been proposed to predict students final performance. Despite of several machine learning
approaches such as ANNs, SVMs, etc. associative classifiers maintain interpretability along
with high accuracy. In this research work, we have employed Honeybee Colony Optimization
and Particle Swarm Optimization to extract association rule for student performance prediction
as a multi-objective classification problem. Results indicate that the proposed swarm based
algorithm outperforms well-known classification techniques on student performance prediction
classification problem.

1. INTRODUCTION
As the volume of archived data increases, the need for more efficient and faster data analysis
techniques increases concurrently. All of the saved records in databases of organizations would
be useless, if decision makers do not employ effective knowledge discovery techniques. Data
mining methods analyze huge amount of databases to discover valuable and ready to use
knowledge [8].
Nowadays, data mining techniques have been used in academic and educational environments
and leave a remarkable effect in this domain [9]. Educational Data Mining (EDM) refers to the
employment of knowledge discovery techniques and methods in education. The main goal of
EDM is to enhance various educational activities such as student performance prediction,
education facility improvement, etc.](https://image.slidesharecdn.com/associationrulediscoveryforstudentperformancepredictionusingmetaheuristicalgorithms-151118103305-lva1-app6891/85/Association-rule-discovery-for-student-performance-prediction-using-metaheuristic-algorithms-1-320.jpg)

As mentioned above, EDM is a domain that uses machine learning, data mining and statistical
techniques, analyses educational data. Thanks to employ of these techniques, it is possible to
improve the learning/teaching processes involving students or instructors.
Educational data come in many different and very complex formats. The last surveys in this
scope is related to (Alejandro Pena-Ayala,2013), establishing the following EDM approaches [1]:
• Student behavior modeling
• Student performance modeling
• Student modeling
• Assessment
• Curriculum, domain knowledge, sequencing, and teachers support
• Student support and feedback
Other survey is related to Romero and Ventura [2], which is survey on educational data mining
between 1995 and 2005. Using data mining techniques in higher education is a recent research
domain; there are a lot of works in this area. That is because of its potentials to educational
institutes.
Ayesha et al. employed the k-means data mining clustering algorithm to predict students’
learning activities in an educational database including classroom quizzes, final and mid exam
and other assignments. This correlated information will be conveyed to the teacher before the
transfer of final exam. This study helps the teachers to improve the performance of students and
reduce the failing ratio by taking appropriate steps at on time [3].
Baradwaj and Pal, in the year 2011, used the classification as data mining methods to evaluate
student’ performance, they applied decision tree technique for classification. The aim of their
research is to extract knowledge that describes students’ performance in end semester quizzes.
They used students’ educational data from the student’ previous database including Class test ,
Assignment marks , Attendance, , Seminar. This study helps sooner in identifying the students
who need more attention and allow the teacher to provide appropriate advising [4].
Chandra and Nandhini, applied the association rule mining method based on students courses to
identifies students’ break patterns. The aim of their research is to identify hidden relationship
between the failed courses and suggests relevant causes of the failure to improve the low capacity
students’ performances. The extracted association rules lay out some hidden patterns of students’
courses which could serve as a foundation stone for academic planners in making decisions and
modification and an aid in the curriculum re-structuring with a view to improving students’
performance and reducing break rate [5].
Shannaq et al, used the classification since data mining technique to predict the numbers of listed
students by evaluating academic data from enrolled students to study the main attributes that may
affect the students’ truth (number of enrolled students) [6].The decision tree as a classification
method to extract classification rules and the extracted classification rules are analyzed and
evaluated using different evaluation methods. It allows the University management to prepare
necessary resources for the new enrolled students and indicates at an early stage which type of
students will potentially be enrolled and what areas to focus over in higher education systems for
support and feedback.](https://image.slidesharecdn.com/associationrulediscoveryforstudentperformancepredictionusingmetaheuristicalgorithms-151118103305-lva1-app6891/85/Association-rule-discovery-for-student-performance-prediction-using-metaheuristic-algorithms-2-320.jpg)

Made a prediction model using the GP method to identify at-risk students in traditional school
settings. A feature selection technique was used to reduce the attributes [7].
Wolff et al. (2013) have applied a decision-tree as data mining techniques to identify at-risk
students in a virtual learning environment.
In this paper a new associative classification technique has been proposed to predict students
final performance. In this research work, we have employed Honeybee Colony Optimization and
Particle Swarm Optimization to extract association rule for student performance prediction as a
multi-objective classification problem. Results indicate that the proposed swarm based algorithm
outperforms well-known classification techniques on student performance prediction
classification problem.
The rest of this paper is organized as follows: Section 2 presents the new proposed classification
method for student performance prediction.
2. PROPOSED METHOD
In this section, we introduce a new approach, called Bee-RM, of multi-objective optimization
based on the optimization of bee colony algorithm and particle swarm optimization.
In the following, we present the outlines of our proposed approach.
Association rule extraction is widely used data mining tasks. This is due to the interpretability
feature of these rules for non-experts. The extraction of the association rules is usually performed
using the meta-heuristic algorithms. In this paper, we take two major factors into consideration
regarding the classification: the first one is the accuracy and the second is Interpretability.
The knowledge base used in this work is presented as a rule base. It is an important issue to select
a set of optimum rules in these systems. In our Bee-RM approach, the rule extraction is
performed using “pareto optimality” and considering the multi-objective factor.
Since there is rarely a unique solution which optimizes all objective functions, we look for a
trade-off between objectives instead of seeking a unique solution for multi objective
optimization.
2.1 RULE GENERATION BY BEE_RM
In this work, we decided to continuously extract rules as there is only few works which perform
continuous rule extraction. The advantage of the continuous rule extraction is that the whole
space is explored. However, the whole space exploration needs a lot of space, which demands to
use more powerful algorithms.
In the following, we present how to model the association rules using the bee colony optimization
and particle swarm optimization (PSO). Each member of the population is presented as an array
with three rows. Then, each association rule is created by a member.
Since rules are created for each class, we use class zero as an example.](https://image.slidesharecdn.com/associationrulediscoveryforstudentperformancepredictionusingmetaheuristicalgorithms-151118103305-lva1-app6891/85/Association-rule-discovery-for-student-performance-prediction-using-metaheuristic-algorithms-3-320.jpg)

Table 3 shows accuracy of Bee_RM versus several recent and famous classification methods.
We used 3 famous tools in data mining, for comparison.
To compare our results with other studies, we have used WEKA, Rapidminer and KEEL
softwares.
Six evolutionary rule learning algorithms are used in which 3 of them learn fuzzy rules and 3 of
them learn crisp rules in an evolutionary way. These results reveals, our proposed method
Bee_RM using 10-fold cross validation obtains the highest classification accuracy, 53.46%,
reported so far. So, we can draw this conclusion that the combination of Bee Colony
Optimization and particle swarm optimization with continues logic, would be very effective in
predicting student final performance in educational data.
Although there is not any accurate definition for interpretability of classification methods but the
number of rules (NR) and mean length of rules(Len) are often mentioned as two main factors of
interpretability.
4. CONCLUSIONS
In this paper we employed the capability of swarm based techniques to extract association rules
for student performance prediction as a multi-objective classification problem. The proposed
algorithm had a low convergence time and it used a few number of parameters. Honeybee Colony
Optimization and Particle Swarm Optimization were the two used metaheuristics to extract
association rules. The fitness function in both of these algorithms considers support and length of
the association rules. Results showed that using the proposed metaheuristic-based rule discovery
approach enables us to extract accurate and interpretable knowledge for student performance
prediction. Our future works focus on using new proposed metaheuristic algorithms such as
Gravity Search and Vortex Search Algorithm instead of PSO and Honeybee Colony. Moreover,
we aim to consider other measures such as confidence, correlation and interestingness along with
support and rule length.

Each member of the population is presented as an array with three rows. Then, each association rule is created by a member. Since rules are created for each class, we use class zero as an example.
- 4. 118 Computer Science & Information Technology (CS & IT) In the first array, “A” presents absence and “P” presents the specific property in the rule. In this approach, we do not need to perform bins and so the span is seen continuously. The second array’s values show the lower limit of each property. The third array shows the upper limit of each property. Therefore, the rule presented by these arrays is: 0=classthen7<F4<8.5)and(0.2<F1<0.9If The first array contains discrete values, in the ConstructSolution function, we use the bee colony optimization in order to predicate and in the case of two other arrays which present the span, we use PSO optimization. In the first fold of each category in the dataset, the generation is performed “MaxGeneration “ times. Inside each generation, the population size is equal to the value of “Population” parameter. In each execution of the algorithm, for each class in the dataset, the generation is performed and every member of the population produces the optimized results. Then, we use the “optimized association rules extracted for all classes” as input of the classifier method in order to classify the test dataset. Finally, the average accuracy obtained by 10-fold execution is considered as the main accuracy of the Bee_RM algorithm. 2.2 HONEYBEE HIVE OPTIMIZATION (HHO) The “ConstructSolution” method for optimizing the first array, create a path for each bee according to the Dance Table and heuristic information.

- 5. Computer Science & Information Technology (CS & IT) 119 2.3 PARTICLE SWARM OPTIMIZATION (PSO) We use the particle swarm optimization (PSO) algorithm in a continuous space and in multi objective form. The objective function in Eq (3) is used to calculate the Local-best found by each individual inside the same individual. The Global-best found in the whole population of individuals is kept in another variable called Gbest in each individual. In other word, we do not have a unique Global-best but many. Fitness = Support Percent*Support (solution) + (1-SupportPercent)* Confidence (solution) (3) All Gbest are the most optimized local Non-dominated association rules obtained by Eq (4) optimization in the current population. To calculate the location of the next move of particle, we use the average of these local Non-dominated rules as demonstrated in the Eq(5) and Eq(6). The more general rules cover a big span of the dataset records. It reduces the interestingness of the rules. Our objective is to make a trade-off between interestingness and support value of obtained association rules. We try to extract more detailed association rules with high support value and interestingness by defining the “Interval-p” parameter. 2.4 STOPPING CONDITION Once all rules are created by all members of the current population, local non-dominated and global non-dominated rules are determined. The most important condition to stop the training phase is a constant number of repetitions. The members continue the procedure till the stop condition is satisfied. The procedure stops if the repetition number of procedure is reached (the “Maxgeneration” number). Then, the best association rules according the Pareto-optimality optimization are selected. 3. EXPERIMENTAL RESULTS This section shows the experimental results of the proposed method versus other classification techniques. Our proposed method will be analyses educational data generated on a Moodle platform. Moodle’s log is the baseline system used in this research. Moodle is a free virtual learning environment (VLE). Moodle is therefore evolving system and dynamic. Anyone can download and install it. An administrator is responsible for managing users (students, teachers, etc.) and course virtual classrooms. The Moodle system view differs depending on the role the user plays (teacher, student, administrator etc.).
- 6. 120 Computer Science & Information Technology (CS & IT) Moodle is developed by programmers as an open source system, from all over the world. As of 2013, Moodle system has over 77,000 registered sites in over 215 countries. It prepares support to over 65 million students all over the world, trained by over 1.2 million teachers. Moodle is only one of many support tools for virtual learning environment (VLE). There are other similar distance systems like, for example, ATutor, eCollege, Desire2Learn or Dokeos. The information of interaction is stored as attributes in a user (student) profile. In our data set, 11 attributes and values are stored, with 357 records. These attributes include: number of interaction between student-student, student-teacher, and etc. Detail of this data set is as follows. Table 1 shows detail information about attributes of Moodle data set. Experimentally, we have tried to set the best parameters for proposed method. The values of different user-defined parameters of Bee_RM is reported in Table 2. Table 1.Information about features of Moodle dataset.
