We propose a distributed approach addressing the problem of distance-based outlier detection in very large data sets. The presented algorithm is based on the concept of outlier detection solving set ([1]), which is a small subset of the data set that can be provably used for predicting novel outliers. The algorithm exploits parallel computation in order to meet two basic needs: (i) the reduction of the run time with respect to the centralized version and (ii) the ability to deal with distributed data sets. The former goal is achieved by decomposing the overall computation into cooperating parallel tasks. Other than preserving the correctness of the result, the proposed schema exhibited excellent performances. As a matter of fact, experimental results showed that the run time scales up with respect to the number of nodes. The latter goal is accomplished through executing each of these parallel tasks only on a portion of the entire data set, so that the proposed algorithm is suitable to be used over distributed data sets. Importantly, while solving the distance-based outlier detection task in the distributed scenario, our method computes an outlier detection solving set of the overall data set of the same quality as that computed by the corresponding centralized method.
