The density-based local outlier detection algorithm (LOF) is not suitable for detecting the data set which is high dimension and polysemous. In this paper
we popose a local outlier detection algorithm based on multi-label learing(MLL-LOF).The main ideal of the MLL-LOF algorithm is as follows: Firstly
the real object data is divided into multi-instance by using an MLL framework
then the MLL-LOF calculates the final outlier factor and detects outliers by using degradation strategy and weight adjustment. We compare the MLL-LOF algorithm with other classical local outlier detection algorithms by using actual data set which is comes from enterprise monitoring. Experimental results show that the precision
recall
F1 and time efficiency of the MLL-LOF algorithm are superior to the traditional local outlier detection algorithm.
