Anomaly Detection API Reference
ChemometricsTools has a few anomaly detection methods. Feel free to read the API below. If that's too abstract, check out the shoot-out example : AnomalyDetection
Functions
ChemometricsTools.OneClassJKNN
— Method.OneClassJKNN( Normal, New; J::Int = 1, K::Int = 1, DistanceType = "euclidean" )
Creates a one class JK-NN classifier from Normal
data and evaluates it on New
data. This compares the inter sample distance (DistanceType
) between a New
and Normal
J nearest neighbors to the K nearest neighbors of those J nearest neighbors in the Normal
set. No cut off is provided, that should be done by the end-user. A typical cut off value is 1.0 .
