Witryna14 maj 2024 · The Local Outlier Factor (LOF) algorithm finds outliers by measuring the local deviations to a given data point. The algorithm is based on a concept of local point density. The density is described by distance to the k-nearest neighbors. By comparing the density of each instance, regions with similar density can be identified.

Informally, the algorithm works by comparing the local density of a point to the local densities of its k nearest neighbors. Points with local densities lower than their neighbors will be classified as outliers.
