More than 2,000 researchers, including several employees of Microsoft, Amazon, Google, Netflix and other companies, have signed an open letter to revolt against Nature Machine Intelligence, a proposed new paywalled (closed-access) journal from Nature Publishing Group. The researchers said they won't "submit to, review, or edit" anything for the new publication. Nature Publishing Group has responded to the protest saying it is "providing a service -- for those who are interested -- by connecting different fields, providing an outlet for interdisciplinary work and guiding a rigorous review process." The open letter, posted on Oregon State University's site, adds: We see no role for closed access or author-fee publication in the future of machine learning research and believe the adoption of this new journal as an outlet of record for the machine learning community would be a retrograde step. In contrast, we would welcome new zero-cost open access journals and conferences in artificial intelligence and machine learning.
