On 16th of November we‘ve had the honour to synchronize on WP4 research activities with experts from NIST, INMETRO and Ericsson. Productive discussions with Irena Bojanova (NIST: https://www.nist.gov/people/irena-bojanova ), Carlos Galhardo (INMETRO https://www.linkedin.com/in/carlos-galhardo-a7aba462/) and Alf Larsson (Ericsson: https://www.researchgate.net/profile/Alf-Larsson) build on considerations for Taxonomy (T4.1) that forms the research basis on which ML-based failure prediction algorithms are developed within T4.2.
