# Clifford Data Regression#

Clifford data regression (CDR) is a learning-based quantum error mitigation technique in which an error mitigation model is trained with quantum circuits that *resemble* the circuit of interest, but which are easier to classically simulate [2, 15].

Below you can find sections of the documentation that address the following questions:

A simple tutorial using CDR can be found on the How do I use CDR? page.
