.. _auto_curves_lookup_classify:

*THIS FUNCTION EXTRACTS THE MIN, MAX, FINAL, TIME AT MIN, TIME AT MAX AND CLASSIFIES THEM BASED ON THE CONDITIONS*
==================================================================================================================

Extracts key statistics (min, max, final value, time-at-min, time-at-max) from each curve in a group and classifies each curve against user-defined label conditions. Use this worker to tag or summarize a batch of curves — e.g., pass/fail, regime labelling — based on their scalar features.

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

Classification: **process**.

Tagged: ``batch``, ``classify``, ``curve_group``, ``final``, ``labelling``, ``lookup``, ``max``, ``min``.

Inputs
------

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

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve Group
     - curve_group
     - vector
     - —
     - 
     - One or more input curves (vector signals) to be analysed; each curve is independently evaluated for its statistical features before classification.
   * - Return Type
     - return_type
     - scalar
     - classifications
     - 
     - Controls output format: 'classifications' returns only the assigned label per curve; 'summary' returns the full statistical feature table alongside labels. Defaults to 'classifications'.
   * - Default Label
     - default_label
     - scalar
     - unclassified
     - 
     - String label assigned to any curve that does not satisfy any of the defined conditions (e.g. 'unclassified'). Defaults to 'unclassified'.
   * - Conditions
     - conditions
     - labelcondition
     - —
     - 
     - One or more label-condition rules (labelcondition type) that map feature thresholds or logical expressions to a named class; evaluated in order against each curve's extracted statistics.

Outputs

     - Type
     - Description
   * - curves_lookup_classify_output_1
     - curves_lookup_classify_output_1
     - dataset
     - Dataset containing either the classification labels only or a full summary table (min, max, final, time-at-min, time-at-max, assigned label) for every input curve, depending on the selected Return Type.
