Predictor (Classification)
Overview
You can use this Snap to predict the class (target/class) field for an unlabeled document. An unlabeled document is one that does not have a class field. So, the Snap reads this unlabeled document and predicts the class field. Predictions are made based on the classification model built by the Trainer (Classification) Snap.
Transform-type Snap-
Works in Ultra Tasks
Prerequisites
- The data from upstream Snap must be in tabular format (no nested structure).
Limitations and known issues
None.

Required. Specify a unique name for the Snap. Modify this to be more appropriate, especially if more than one of the same Snaps is in the pipeline. Default value: Predictor Classification data Example: Classification model |
| Max output | Integer/Expression | Required. Enter The maximum number of predictions for each row in the input document. The predictions are in descending order of their confidence level. Default value: 1 Example: 5 |
| Confidence level | Checkbox | If selected, the Snap's output includes the confidence level for each prediction. The prediction with the confidence level that is closest to 1 is most likely to be the correct class field. Default status: Not selected |
| Snap execution | Dropdown list | Choose one of the three modes in which the Snap executes. Available options
