.. _auto_dataset_classifier:

*DATASET CLASSIFIER*
====================

Applies a rule-based classifier to a dataset, assigning each row to a category based on user-defined filter/classification rules. Use this worker to label or segment dataset records without training an ML model.

When to use
-----------

Classification: **process**.

Tagged: ``classifier``, ``dataset_classification``, ``labeling``, ``rule_based``, ``segmentation``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Dataset
     - dataset_1
     - dataset
     - —
     - 
     - Input dataset (tabular) whose rows are to be classified; connect any dataset output from an upstream worker — leave unconnected only if classification is to be run on a pre-loaded dataset.
   * - Classifications
     - classifications
     - classifier
     - —
     - 
     - Rule-based classifier definition (filter conditions and corresponding class labels) that drives the classification logic; the available filter fields are automatically derived from dataset_1.

Outputs
-------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20

   * - Label
     - ID
     - Type
     - Description
   * - dataset_drop_columns_output_1
     - dataset_drop_columns_output_1
     - dataset
     - Output dataset identical in structure to the input but augmented with a classification label column indicating the assigned category for each row.
