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.
Snap views
| View | Description | Examples of upstream and downstream Snaps |
|---|---|---|
| Input | This Snap has at most two input views. Any Snap that generates an unlabeled document. Any Snap that reads and outputs the classification model. | |
| Output | This Snap has at least one and at most one document output views. | File Reader |
| Error |
Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the pipeline by choosing one of the following options from the When errors occur list under the Views tab. The available options are:

| Label | String |
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 | Select one of the three modes in which the Snap executes.
