We are making bigger demands on the internet all the time. Machine learning (ML) and artificial intelligence (AI) will make the internet and optical communications more powerful, reliable and robust. The MSCA (Marie Sklodowska Curie Actions) European Industrial Doctorate (EID) MENTOR (Machine Learning in Optical Networks) has six EC-funded ML&AI Early Stage Researchers (ESRs) working on cutting-edge optical networks. Find out more on ML&AI and the amazing MSCA programmes by taking a listen! MENTOR is funded by EC Horizon 2020, under MSCA Grant 956713.
