Dr Diarmuid Grimes

introd​uction

My research involves the application of machine learning techniques and optimisation technologies to real-world problems, such as condition-based maintenance for trains (predict health of train components based on sensory data, schedule maintenance taking this prediction into account together with constraints on staff, maintenance depot, etc.), and energy optimisation (optimally schedule energy consumption such that cost is minimised using predicted energy prices), etc.
