Two Stages

Both fuzzy c-means (FCM) clustering and outlier detection are useful data mining techniques in real applications. In this paper, we show that the task of outlier detection could be achieved as by-product of fuzzy c-means clustering. The proposed strategy consists of two stages. The first stage consists of purely fuzzy c-means process, while the second stage identifies exceptional objects according to a novel metric based on the entropy of membership values. We provide experimental results to demonstrate the effectiveness of our technique.

Consumers an important asset in a company that should be maintained properly especially potential customers. Tight competition requires companies to focus on the needs of the customer wants. Consumer segmentation is one of the processes carried out in the marketing strategy. To support the grouping process results consumers or consumer segmentation data mining is the support of a very important role. Based on mapping studies on data mining in support of consumer segmentation obtained two algorithms are often used for consumer segmentation include a K-Means Clustering and Fuzzy C-Means clustering. The attributes used for mining in customer segmentation processes are customer data, products, demographics, consumer behavior, transactions, RFMDC, RFM (Recency, Frequency Monetary) and LTV (Life Time Value). And it is important to combine the clustering algorithm to algorithm Classification, Association, and CPV to get the potential value of each cluster.

Student Graduation

Analysis and excavation of information on educational data is an inseparable part of organizing student academic systems in universities. The excavation of information is known as Educational Data mining (EDM), which is a discipline that focuses on the application of techniques and data mining devices specifically in the field of education. One of the EDM processes is related to the need for prediction especially to gain knowledge regarding the progress of student studies. Practically the activity of getting information / knowledge about the progress of student studies is difficult to do conventionally considering the size of the data volume is quite large. The approach to data mining clustering on student study progress data for prediction of predicate graduation tends to be not optimal. Fuzzy C-means (FCM) modeling optimized with Particle Swarm Optimization (PSO) can produce a more optimal prediction performance. In the case of prediction of student graduation prediction, the application of PSO-based FCM algorithm model produces more optimal results, with predictive accuracy of 86% while the FCM algorithm modeling is 79%.

Snorkeling adalah salah satu hobu yang sangat digemari saat ini. Snorkeling sering di lakukan untuk refreshing sambil menyegarkan pikiran setelah berkutat dengan aktifitas dan pekerjaan yang menguras pikiran. Piranti atau (peralatan) snorkeling yang paling utama terdiri dari 4 alat yaitu, masker selam, baju selam, snorkel dan kaki katak atau sirip selam. Dalam penerapanya banyak kendala yang dihadapi para penyelam terutama dalam hal memilih piranti masih bersifat manual yaitu para penyelam hanya mendapat informasi dari instruktur snorkeling yang berada di kawasan snorkeling. Keadaan tersebut sudah pasti membuat proses pemilihan menjadi tidak efesien karena keterbatasan informasi yang bisa didapat sehingga perlunya dibuatkan sebuah sistem pendukung keputusan. Fuzzy C-means Clustering (FCM) adalah suatu teknik pengelompokan data yang mana keberadaan tiap-tiap titik dalam suatu cluster ditentukan oleh derajat keanggotaan. Pada penelitian ini akan digunakan metode perhitungan FCM untuk menentukan piranti yang tepat untuk direkomendasikan kepada User. Dengan adanya sistem pendukung keputusan dapat membantu user dalam memilih piranti yang sesuai dengan kriteria yang diinginkanya.

Fuzzy C Means Clustering

Technical organisations are ranked based on performance indicators like resources, students' intake, global reputation, and research activities. Student performance and placement are important factors in deciding the ranking of a university. Student performance analysis is a recent and widely researched domain aimed at reforming the education system. The analysis assists institutions to understand and improve their performance and educational outcomes. Admissions, academics, and placement are the three most significant processes during which the large amount of data is gathered within a university and there is a requirement of analysis. The data mining techniques are used for data analysis processes and it encompasses data understanding, pre-processing, modelling, and implementation. In this research work, fuzzy c-means clustering technique is used to understand fuzziness of student performance, classify and map the student performance to employability. To understand this objective, the dataset has been collected from universities, pre-processed, and analysed.

Learning Interest

<p class="0abstract">Students' learning interest and motivation in programming language to date are determined by their scores and abilities to create applications. However, this is not sufficient to identify students' learning interest in programming language because some students got low scores. This study aims to identify students' learning interest in Dipanegara school of informatics management and computer (STMIK), Makassar, in Java programming language. The samples were 65 technical information students and 63 information system students. The data collection technique of this study was questionnaire and processed with data mining technique. Additionally, Fuzzy C-Means clustering method was applied on Java Netbeans programming language to classify the level of students' interest in studying Java programming language.   The result of the study was a web-based application that could determine students’ learning interests. It was obtained through questionnaires and resulted as follows: 47 students had high learning interest, 45 students had moderate interest, and 36 students had fair interest out of 128 samples.</p>

Fuzzy C Means Clustering

Finding pathogenic factors and how they are spread in the environment has become a global demand, recently. Cutaneous Leishmaniasis (CL) created by Leishmania is a special parasitic disease which can be passed on to human through phlebotomus of vector-born. Studies show that economic situation, cultural issues, as well as environmental and ecological conditions can affect the prevalence of this disease. In this study, Data Mining is utilized in order to predict CL prevalence rate and obtain a risk map. This case is based on effective environmental parameters on CL and a Neuro-Fuzzy system was also used. Learning capacity of Neuro-Fuzzy systems in neural network on one hand and reasoning power of fuzzy systems on the other, make it very efficient to use. In this research, in order to predict CL prevalence rate, an adaptive Neuro-fuzzy inference system with fuzzy inference structure of fuzzy C Means clustering was applied to determine the initial membership functions. Regarding to high incidence of CL in Ilam province, counties of Ilam, Mehran, and Dehloran have been examined and evaluated. The CL prevalence rate was predicted in 2012 by providing effective environmental map and topography properties including temperature, moisture, annual, rainfall, vegetation and elevation. Results indicate that the model precision with fuzzy C Means clustering structure rises acceptable RMSE values of both training and checking data and support our analyses. Using the proposed data mining technology, the pattern of disease spatial distribution and vulnerable areas become identifiable and the map can be used by experts and decision makers of public health as a useful tool in management and optimal decision-making.
