A Robust Scalable Model Using Hybrid Approach for the Detection of the Projected Outliers

並列摘要


The abnormal and anomalous observations even in the advanced technological era proves to be the biggest jolt to the concerned industry. To reduce and eliminate the outliers from the massive data streams, it is important to accurately highlight them from the higher dimensional data which is itself very challenging. In this study, a Scalable outlier detection model is proposed which is robust enough to resist and detect the projected outliers that are lying at some lower dimensional subspaces. This model exploits the problem of curse of dimensionality which is very frequent in large data streams and massive datasets. Rapid distance and density based approaches are used and then the probability density is measured by Gaussian Mixture Model. Baye's Probability is applied to the final observations so as confirm them as the projected outliers.
