Abstract

Waiting is a boring thing for some people, let alone having to queue up in long queues. In everyday life waiting in a queue is a common thing, for example the queue at the bank teller. This queue can occur due to the arrival of the increasingly enlarged and can not be offset by existing services. A long queue will keep people waiting until they get bored and even leave. This will make the bank losers due to loss of customers, on the contrary if there is no queue then the service facility (teller) many unemployed will cause losses for the bank. So needed a solution to overcome this, one of them is by simulation. Simulations are performed to simulate real existing queuing systems with properties that are easier to observe than the original system, to determine the performance of the system. In this research, Hyperexponential method is used to calculate service time with single channel to observe how system performance. Based on the results of the study, the server obtained adequate to serve is as much as 3 servers, if only 1 or 2 servers will result in the average waiting time is too long which resulted in customers will be bored waiting while while using 4 servers will result in the average waiting time zero so the server is idle

Abstract

Unbalanced data classification is a crucial problem in the field of machine learning and data mining. Data imbalances have a poor impact on classification results where minority classes are often misclassified as a majority class. k-Nearest Neighbor is one of the most popular and simple classification methods but it is not equipped with the ability to work on unbalanced datasets. In this study, the Synthetic Minority Over-Sampling Technique (SMOTE) was applied to solve the class imbalance problem on the Credit Card Fraud dataset. By applying the 10-cross-validation evaluation scheme, it was found that SMOTE increases the mean of  G-Mean by 53.4% to 81.0% and the mean of  F-Measure by 38.7 to 81.8%Keywords: Class imbalance, Synthetic Minority Over-sampling Technique, k-Nearest Neighbor
