Noise-driven enhancement: deep reinforcement learning for autonomous UAV navigation
Tsinghua University PressPeer-Reviewed Publication
The exploration-exploitation dilemma is a long-standing topic in deep reinforcement learning. In recent research, a noise-driven enhancement for exploration algorithm has proposed for UAV autonomous navigation. This algorithm introduces a differentiated exploration noise control strategy based on the global navigation training hit rate and the specific situations encountered by the UAV in each episode. Furthermore, it designs a noise dual experience replay buffer to amplify the distinct effects of noisy and deterministic experiences. This approach reduces the computational cost associated with excessive exploration and mitigates the problem of the navigation policy converging to a local optimum.

Health data for 57 million people in England show changing patterns of heart diseases before, during and after the pandemic
Health Data Research UKPeer-Reviewed Publication
A comprehensive study of electronic health records for 57 million people living in England has revealed the evolving burden of cardiovascular diseases before, during and after the COVID-19 pandemic.
The study was led by scientists at the Universities of Edinburgh, UCL, and Cambridge with technical and data support from the BHF Data Science Centre at Health Data Research UK. The insights gained into the patterns of multiple heart diseases reveal important health inequalities during and after the COVID-19 pandemic that can be targeted to improve cardiovascular health.
