چکیده
Breast cancer is non-skin that caused by several factors, including glandular ducts, cells, and breast support tissue, except for the skin of breast. if not treated immediately will be fatal sufferer, so early detection important patient's safety. The success depends on right diagnosis. Measurement accuracy a diagnosis can assisted statistical methods, namely classification. K-Nearest Neighbor classification algorithm based nearest neighbor easy to implement. In process, there are problems when faced with imbalanced data. Imbalanced data cause algorithms tend focus majority class. Data imbalance overcome using Synthetic Minority Oversampling Technique (SMOTE). Ensemble methods applied improve performance classification, one which Adaptive Boosting. This study applies combined Boosting SMOTE handling results this are, handle problem application produce an 80%, sensitivity 83,33%, specificity 66,67%, G-Mean value 74,54%. So it concluded

The problem of imbalanced data, i.e., when the class labels are unequally distributed, is encountered in many real-life application, e.g., credit scoring, medical diagnostics. Various approaches aimed at dealing with the imbalanced data have been proposed. One of the most well known data pre-processing method is the Synthetic Minority Oversampling Technique (SMOTE). However, SMOTE may generate ...

متن کاملk-Nearest Neighbor Classification on Spatial Data
Classification of spatial data streams is crucial, since the training dataset changes often. Building a new classifier each time can be very costly with most techniques. In this situation, k-nearest neighbor (KNN) classification is a very good choice, since no residual classifier needs to be built ahead of time. KNN is extremely simple to implement and lends itself to a wide variety of variatio...
