TD_OneClassSVM produces two outputs:
  • Model (Primary output): Contains the trained model along with model statistics. These model statistics will be stored in the model:
    • Loss Function
    • MSE
    • Number of Observations
    • Loglik
    • AIC
    • BIC
    • Regularization
    • Alpha (L1/L2/Elasticnet)
    • Number of Iterations
    • Learning Rate (Initial)
    • Learning Rate (Final)
    • Momentum
    • Nesterov
    • LocalSGD Iterations
  • MetaInformationTable (Secondary Output - Optional): Contains training progress information for each epoch.

Model Output Schema

Column Data Type Description
attribute SMALLINT Contains a numeric index of predictor and model metrics. Intercept is specified using index 0 and rest of the predictors take positive values. Model metrics take negative indices.
predictor VARCHAR Contains the name of the predictor or Model metric.
estimate FLOAT Contains the predictor weights and numeric-based metric values.
value VARCHAR Contains the string-based metric values (for example., HINGE for LossFunction, L2 for Regularization, and so on).

MetaInformationTable Output Schema

Column Data Type Description
iteration INTEGER Contains iteration number (epoch number).
num_rows BIGINT Contains total number of rows processed so far.
eta FLOAT Learning rate for the iteration.
loss FLOAT Contains loss in this iteration.
best_loss FLOAT Contains best loss till this iteration.
