Local Outlier Factor algorithm for detection of anomaly samples.

LOF（局部异常因子）是用于识别基于密度的局部异常值的算法-It uses local outlier mining method to count the Local Outlier Factor(LOF) of the outlier candidated object。

该算法，解决了不收敛的问题，聚类效果非常好。改进的蚁群算法是基于遗传算法的改进，在基本遗传算法的基础之上，加入了变异因子，产生变异，从而更快的收敛。-The algorithm solves the problem of convergence, and the clustering effect is very good. The improved ant colony algorithm is based on the improvement of genetic algorithm. O
