Therefore, a machine learning algorithm is needed to help predict CRF, one of which is the Extreme Gradient Boosting (XGBoost) algorithm. However, XGBoost has one thing that must be considered, namely the presence of hyperparameters that need to be tuned. In this research, tuning was done using grid search and random search methods, which would be compared to get a good performance and help predict GGK. In the dataset used, several features were incomplete, so that data cleaning was carried out. Based on the unbalanced amount of data, oversampling with SMOTE and random oversampling methods were needed to balance the data. Next, the data were normalized using two: min-max and z-score normalization. After the data had been normalized, a splitting process was performed with a division of 70% for training data and 30% for testing data. Furthermore, the hyperparameter was tuned to obtain the optimal parameter value, which was then performed data processing and evaluated to obtain the accuracy and f-measure values of the tuned parameter values. In the grid search method with data performed with min-max and z-score normalization combined with oversampling random oversampling, the best results were obtained with an accuracy value of 99.28% and an f-measure value of 0.9942. Comparison with other methods was carried out and the proposed method obtained an accuracy of 99.33% and f-measure 1.0.

Hence, it provides services or products such as term deposits. Term deposits give banks the most reliable source of profit and credits. Bank uses direct marketing to attract customers to subscribe to the deposit program. By using data mining, a bank can predict the client who will subscribe to the term deposit program. In this research, the dataset to be tested is bank marketing by Portuguese banking institutions. The data mining algorithm used is K-Nearest Neighbors (KNN), but it has a sensitive weakness to outliers which causes the accuracy of this algorithm is not good. This research aims to cover up the weakness of the KNN by detecting outliers in the dataset and improving the accuracy of the KNN. The outlier detection method used in this research is Subspace Outlier Detection (SOD) and Principal Component Analysis (PCA) as dimensional reduction method. The dataset was splitting into 70% training data and 30% testing data as new data. K-fold cross-validation was used to search the K Neighbors value of KNN during the modeling training data. The classification results of testing data based on the confusion matrix show the accuracy of the KNN algorithm which only uses PCA is 91%. While the KNN algorithm accuracy with SOD and PCA is 94%. It can be concluded that the accuracy of KNN using SOD is better than accuracy of KNN without SOD by improving the accuracy by 3% in the bank marketing dataset.
