An Approach For Supervised Distance Based Outlier Detection
Outlier detection simply refers to the process of finding outlying object from a dataset. It is the object having
different properties as compare to the entire set of data. Outlier detection became important subject in different knowledge
domains. Size of data is getting doubled every years there is a need to detect outliers in large datasets as early as possible. It
is crucial to find outliers from large dataset because of curse of dimensionality. If no of outliers present in dataset there is a
possibility of increase false negative rate. This paper presents a brief description of support vector machines. Also we have
tried to provide the broad and a comprehensive literature survey of outliers and outlier detection techniques. SVM mainly
focus on high dimensionality of data, this method are a specific type of machine learning method which is most widely-used
for many statistical learning problems.
