A Proactive Cloud Application Auto-Scaler using Reinforcement Learning Open
This work explores the use of reinforcement learning to design a proactive cloud resource auto-scaler that is able to predict usage across a distributed microservice application. The focus is on serving time-sensitive workloads, e.g., indu…

Adaptive Control of Data Center Cooling using Deep Reinforcement Learning Open
In this paper, we explore the use of Reinforcement Learning (RL) to improve the control of cooling equipment in Data Centers (DCs). DCs are inherently complex systems, and thus challenging to model from first principles. Machine learning o…

Sensitivity analysis of the effects of non-pharmaceutical interventions on COVID-19 in Europe Open
The role of non-pharmaceutical interventions (NPIs) on the spread of SARS-CoV-2 has drawn significant attention, both scientific and political. Particularly, an article by the Imperial College COVID-19 Response Team (ICCRT), published onli…

On the sensitivity of non-pharmaceutical intervention models for SARS-CoV-2 spread estimation Open
Introduction A series of modelling reports that quantify the effect of non-pharmaceutical interventions (NPIs) on the spread of the SARS-CoV-2 virus have been made available prior to external scientific peer-review. The aim of this study w…
