CURVE_FIT_POLYNOMIAL

Two new inputs called ‘Smallest segment to consider for fit’ and ‘R2 Cut Off for Fit Optimization’ are available in *CURVE_FIT_POLYNOMIAL worker.

CURVE_FIT_POLYNOMIAL worker now supports auto number of Knots. ​

New input options added to limit to certain number of points while searching for knots in worker *CURVE_FIT_POLYNOMIAL

Adjust knots

*CURVES_FIT_POLYNOMIAL worker has new input options called ‘Adjust Knots’ and ‘Number of Knot Adjustments’ in Workflows.​

CURVE_FIT_POLYNOMIAL Worker : Auto

Overview

The *CURVE_FIT_POLYNOMIAL worker is used to fit a polynomial curve to input data. It enables users to approximate relationships between variables by selecting an appropriate polynomial degree.

New Feature: Auto Order Selection

The worker now supports an Auto order option, which automatically determines the optimal polynomial degree based on the coefficient of determination (R²).

When Auto is selected:

• Multiple polynomial degrees are evaluated.
• The R² value is calculated for each fitted model.
• The polynomial order with the best R² score is selected automatically.
• This eliminates the need for manual trial-and-error when choosing the polynomial degree.
