Struct LocalOutlierFactor 

pub struct LocalOutlierFactor { /* private fields */ }

Local Outlier Factor (LOF) kernel.

Density-based anomaly detection using k-nearest neighbors. Points with substantially lower density than their neighbors are anomalies.

Implementations

impl LocalOutlierFactor

pub fn new() -> Self

Create a new LOF kernel.

pub fn compute( data: &DataMatrix, k: usize, contamination: f64, metric: DistanceMetric, ) -> AnomalyResult

Compute LOF scores.

Arguments

• data - Input data matrix
• k - Number of neighbors
• contamination - Expected proportion of anomalies (for threshold)
• metric - Distance metric
