Troubleshooting the Nonlinear Model block

ERROR REPORTED

ACTION REQUIRED

Invalid input port.

All the fields in the input port of the block must be double fields. All fields in the input port are considered inputs to the model.

The model is not trained.

During model construction and configuration, it must be trained by the using the Offline Trainer block.

The input port does not contain all the fields used during configuration.

All the fields required by the model cannot be found in the input port. The fields that are missing will be listed.

The model was trained on more inputs than are provided in the input port.

There are too few input fields in the input port. The input port must only have the fields required by the trained model. This happens when the model was constructed on say 5 fields but only 4 or less were given in the input port.

The model was trained on fewer inputs than are provided in the input port.

There are too many input fields in the input port. The input port must only have the fields required by the trained model. This happens when the model was constructed on say 5 fields, and there are more than 5 fields in the input port.

Input fields have zero variance.

Possible reasons for fields having zero variance are:

• A Master quality field has been used, therefore all fields will have the same quality value of 1 or 0.

• Limits have been set to values that effectively reduces the variance in a field to zero.

• Brushed data has been used over a time window where there was no variance in the data values.

• The original dataset used for the nonlinear model has zero variance.
