inverse_transform: Inverse transform data using a fitted preprocessing pipeline

In multivarious: Extensible Data Structures for Multivariate Analysis

Inverse transform data using a fitted preprocessing pipeline

Description

Reverse the preprocessing transformation, converting transformed data back to the original scale. The preprocessing object must have been fitted before calling this function.

Usage

inverse_transform(object, X, ...)

Arguments

object	A fitted preprocessing object
X	A matrix or data frame of transformed data to reverse
...	Additional arguments passed to methods

Value

The data matrix in original scale

See Also

fit(), fit_transform(), transform()

Examples

# Inverse transform data back to original scale
X <- matrix(rnorm(100), 10, 10)
preproc <- center()
fitted_preproc <- fit(preproc, X)
X_transformed <- transform(fitted_preproc, X)
X_reconstructed <- inverse_transform(fitted_preproc, X_transformed)

# X and X_reconstructed should be approximately equal
all.equal(X, X_reconstructed)
