This research is discussing about the usage of data mining which addressed for bearing fault diagnosis. Bearing was one of the essential parts in industry machinery. Bearing was used to reduce machines frictions or could be a moving component which oppressed each other.  This fault diagnosis can avoid loss and damage of other machines components. This research was started with data preprocessing using wavelet discrete transformation, feature extraction, feature reduction using Principal Component Analysis (PCA), and classification process using Naïve Bayes classifier methods. Naïve Bayes Classifier is a classification method which based on probability and Bayesian theorem. Output of these method shows that Naïve Bayes classification have a good performance which shown by a good accuracy in each data test.

Data Set

In the current scenario, the researchers are focusing towards health care project for the prediction of the disease and its type. In addition to the prediction, there exists a need to find the influencing parameter that directly related to the disease prediction. The analysis of the parameters needed to the prediction of the disease still remains a challenging issue. With this view, we focus on predicting the heart disease by applying the dataset with boosting the parameters of the dataset. The heart disease data set extracted from UCI Machine Learning Repository is used for implementation. The anaconda Navigator IDE along with Spyder is used for implementing the Python code. Our contribution is folded is folded in three ways. First, the data preprocessing is done and the attribute relationship is identified by the correlation values. Second, the data set is fitted to random boost regressor and the important features are identified. Third, the dataset is feature scaled reduced and then fitted to random forest classifier, decision tree classifier, Naïve bayes classifier, logistic regression classifier, kernel support vector machine and KNN classifier. Fourth, the dataset is reduced with principal component analysis with five components and then fitted to the above mentioned classifiers. Fifth, the performance of the classifiers is analyzed with the metrics like accuracy, recall, fscore and precision. Experimental results shows that, the Naïve bayes classifier is more effective with the precision, Recall and Fscore of 0.89 without random boost, 0.88 with random boosting and 0.90 with principal component analysis. Experimental results show, the Naïve bayes classifier is more effective with the accuracy of 89% without random boost, 90% with random boosting and 91% with principal component analysis.

Naïve Bayes Classifier

Sistem presidensial merupakan salah satu bentuk demokrasi di Indonesia. Sistem tersebut menitikberatkan pada penyelenggaraan pemilihan umum presiden dan wakilnya yang dilakukan secara langsung oleh rakyat. Tingkat terpilihnya seorang presiden dapat dilihat dari opini publik yang beredar, salah satunya pada media sosial yang juga merupakan bagian dari  kampanye. Dalam penelitian ini akan dianalisa opini yang berkaitan dengan elektabilitas calon presiden dari media sosial Twitter dari media sosial Twitter menggunakan metode Naïve Bayes Classifier (NBC) dan menentukan faktor-faktor yang terbentuk dari opini menggunakan Principal Component Analysis (PCA). Data opini dari media sosial Twitter didapatkan menggunakan kata kunci “Jokowi” dan “Prabowo”. Sebagian opini tersebut dipilih sebagai data latih untuk  didapatkan kelas bersentimen negatif dan positif. Setelah proses pelatihan, dilakukan proses terhadap data uji dan data validasi. Hasil akurasi untuk data uji topik Jokowi pada tweet bersentimen positif mendapatkan akurasi sebesar 88.63% dan negatif sebesar 91.06%. Sementara untuk Prabowo bersentimen positif mendapatkan akurasi sebesar 88.58% dan negatif sebesar 80.37%. Rerata akurasi untuk keseluruhan topik adalah adalah 86.89%. Untuk mendapatkan faktor pada setiap sentimen, dilakukan proses perhitungan nilai PCA. Setiap sentimen tersebut kemudian dilakukan analisis faktor oleh pakar, yakni didapatkan 20 faktor yang sudah berhasil diinterpretasikan oleh pakar.

Naïve Bayes Classifier

The classification could be a latent variable that is probabilistically relating to the discovered variables. In Bayesian algorithmic ways, logical thinking works in probabilistic mode. However PCM based parallel abductive reasoning with Naïve Bayes (NB) on cancer information could be a powerful technique to perform effective prediction in classification. Whereas whilst classifying the cancer information the strategy reads the parallel changes and predicts the severity level for supplementary treatments. Since the Bayesian classifier gives many premises for several supervised learning algorithms thereby the proposed Parallel abductive Naïve Bayes Classifier algorithm based on factor analysis of PCA enhances the granularity of prediction. The Principal components are chosen on multi-perspective domain of curator analysis dataset. Experimental result shows that it is potential to get parallel abductive classifiers that have comparatively high impact on prediction.
