Retraction Notice: A Survey on a Nonlinear Regression Application to Machine Learning Techniques for Geomagnetic Data Recons-truction Processing

We take a zero tolerance to any situation where fraudulent research is published in our journals. As a result, this article has been retracted by the Publisher because it is suspected to be a nonsensical computer-generated publication with a number of tortured phrases and irrelevant references. Additional measures have been implemented to prevent these issues from reoccurring. EDP Sciences is extremely grateful to anonymous whistleblowers and the <ns0:ext-link ext-link-type="uri" ns4:href="https://www.irit.fr/%7EGuillaume.Cabanac/problematic-paper-screener">Problematic Paper Screener</ns0:ext-link> [1] for bringing this case to our attention for further investigations.
