ML_PREDICT_ERSATZ Worker Updates
================================

Overview
--------

The ``ML_PREDICT_ERSATZ`` worker has been updated with new input options for configuring the **Ultimate Strain Plateau Column** selection.

New Input Options
-----------------

The following options are now available under the **Ultimate Strain Plateau Column** input field:

* ``eng_mid_uf stress``
* ``eng_mid_uf strain``
* ``eng_mid_yu stress``
* ``eng_mid_yu strain``

Description
-----------

These newly added options allow users to select additional engineering stress and strain datasets for ultimate strain plateau calculations and ERSATZ prediction workflows.

ML_PREDICT_ERSTAZ – Smooth Ultimate Peak Input Option
======================================================

Overview
--------

The ``ML_PREDICT_ERSTAZ`` worker now includes a new input option called **Smooth Ultimate Peak**, enabling controlled smoothing of the ultimate peak response in the prediction output.

This enhancement improves stability and interpretability of predicted results by reducing sharp variations at peak response regions.

Feature Details
--------------

- New input option: **Smooth Ultimate Peak**
- Enables controlled smoothing of ultimate peak response
- Applied during prediction output generation in the ML workflow
- Helps reduce noise and sharp fluctuations near peak values

ML_PREDICT_ERSATZ Worker matrics
=====================================

Overview
--------

The ``ML_PREDICT_ERSATZ`` worker has been enhanced to provide more comprehensive predictive metrics for both **Power** and **Shape** evaluations within the ERSATZ output dataset.

This update introduces additional granular fields, including:

- ``post_power``
- ``damage_max``

These newly added metrics enable deeper analytical insight into ERSATZ prediction behavior and improve downstream post-processing and validation workflows.
