Fit Novelty Detection (One-Class SVM) Node

AI/ML/Classification

Fit a One-Class SVM on normal observations only. Predictions flag whether a new row is an inlier (1) or an outlier (0).

Scores range from 0 to 10. Higher values mean more impact, exposure, or operational weight.

Input

Execution
exec_in

Execution trigger that begins One-Class SVM training

Data Source

String
source

Choose which backend supplies the training data

Default Database
Database

Nu

Float
nu

Upper bound on the fraction of training rows the model is allowed to treat as outliers, in (0, 1]. Raise it when the training set is known to be contaminated.

Default 0.1
Range 0.0001 to 1

Kernel

String
kernel

Feature-space mapping. Gaussian wraps a tight non-linear boundary around the data, Linear yields a half-space, Polynomial adds interaction terms.

Default Gaussian
GaussianLinearPolynomial

Kernel Parameter

Float
kernel_param

Gaussian: the eps in exp(-||x - x'||^2 / eps), larger means a looser boundary. Polynomial: the degree of (<x, x'> + 1)^degree. Ignored for Linear.

Default 30
Range 0.0001 to 1000

Solver Tolerance

Float
tolerance

Stopping threshold of the SMO solver. Smaller values train longer for a more precise boundary.

Default 0.001
Range 1e-7 to 1
