Wire the untrained PCA baseline model output of the Initialize Anomaly Detection Model (PCA T2Q) VI to the reference input of a standard Property Node to get an AML PCA T2Q Property Node. This Property Node has the following properties:

Property Access Data Type Description
Eigenvectors Read Only

Returns the eigenvectors to calculate the principal components. The number of rows equals the number of features of the training data. The PCA baseline model uses a subset of the eigenvectors of the covariance matrix to calculate the principal components in the input data.
Hyperparameters Read Only

Returns the hyperparameters of the PCA baseline model.
Model Initialized? Read Only

Returns whether the model is initialized.
Model Trained? Read Only

Returns whether the model is trained.
Mean Values Read Only

Returns the mean value of each feature in the training data.
Threshold for Q Read Only

Returns the threshold for Q based on confidence level. You can use the threshold for Q to determine whether the Q values of the data for deployment are abnormal.
Threshold for T2 Read Only

Returns the threshold for T2 based on confidence level. You can use the threshold for T2 to determine whether the T2 values of the data for deployment are abnormal.
Variance Read Only

Returns the variance of the principal components. The number of rows equals the number of principal components.
