NORMALIZE THE CURVE USING STATS¶
Reverses a prior normalization operation on a curve by applying the inverse of either Standard Scaler or Min-Max scaling, using the original raw-curve statistics. Use this worker to recover physical-unit curve values after a normalization step in a pre/post-processing pipeline.
When to use¶
Classification: process.
Tagged: curve, denormalize, inverse_transform, minmax, normalization, signal, standardscaler.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve 1 | curve1 | vector | — | The normalized input curve (vector of X/Y pairs) to be de-normalized; connect the output of the upstream normalization worker. | |
| Normalizetype | normalizetype | string | standardscaler | Normalization scheme to invert: ‘standardscaler’ (zero-mean, unit-variance inverse) or ‘minmax’ (min–max range inverse); must match the method used during the original normalization step. Default: ‘standardscaler’. | |
| Axis | axis | string | x | Axis or axes on which to apply the inverse transform: ‘x’ (X-axis only), ‘y’ (Y-axis only), or ‘xy’ (both axes). Default: ‘x’. | |
| Un-normalized Statistics | un-normalized_statistics | keyvalue | — | Key-value map of descriptive statistics (e.g., mean, std, min, max) computed from the original raw curve; these values drive the inverse scaling and must originate from the paired normalization worker. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curve_denormalize_output_1 | curve_denormalize_output_1 | vector | De-normalized output curve (vector of X/Y pairs) with values restored to the original physical-unit scale. |
