Locality-Based Visual Outlier Detection Algorithm for Time Series

Pseudocode 4

HSDE-based outlier detection method.

Input:   the time series

//the maximum of the hierarchy

//the in -distance

//the threshold of the local outlier factor LOF

Output: LOF( )

() HSS = HSDE(X)

() for each in HSS do

Computing the -distance neighborhood of ;

Computing the reachability distance of object ;

According to Formula (3), computing the

According to Formula (4), computing the LOF

if

Label as outlier

() return LOF
