Synthetic Data Generator (Regression)

This component generates example data for a regression task based on the make_regression() function in the Python scikit-learn library.It is possible to control the strength of the linear relationship by adding noise into the generated predictor features.

For more information see the sklearn documentation:

scikit-learn.org/stable/modules/generated/sklearn.datasets.make_regression.html

Note: This component requires a Python environment. In this blog post we explain how to setup the KNIME Python extension:

Options

Amount of Noise
The standard deviation of the Gaussian noise applied to the generated features.
Number of Samples
