We seek two Computer Scientists or Engineers (BSc or Msc holders) in Machine Learning with background in RTD projects. The candidates will participate in the R&D activities of FORTH-ICS in the context of EDF-2021-DIGIT-R-2 project “KOIOS – Knowledge Extraction, Machine Learning and other AI approaches for secure, robust, frugal and explainable solutions in Defence Applications” (EDF-2021-DIGIT-R-2-101103770-KOIOS), funded under EDF-2021-DIGIT-R-2, and will work on Machine Learning and Sensory data processing related aspects. The main objective of our project, KOIOS, is to develop new AI-based methods that are trustworthy (under human control and explainable), robust (resilient to attacks) and frugal in the use of resources (data, computing capabilities, energy,…) addressing tasks in a more efficient manner than the current state-of-the-art ML/DL methods while maintaining similar performance, and improving resilience (for adversarial attacks), consistent behaviour and limiting the cognitive and technical efforts when adapting to new data or dynamic contexts. The candidates will contribute in tasks regarding the ML capabilities of advanced autonomous vehicles.
