Physics-based deep learning reveals rising heating demand heightens air pollution in Norwegian cities

arXiv.org Artificial Intelligence

Policymakers frequently analyze air quality and climate change in isolation, disregarding their interactions. This study explores the influence of specific climate factors on air quality by contrasting a regression model with K-Means Clustering, Hierarchical Clustering, and Random Forest techniques. We employ Physics-based Deep Learning (PBDL) and Long Short-Term Memory (LSTM) to examine the air pollution predictions. Our analysis utilizes ten years (2009-2018) of daily traffic, weather, and air pollution data from three major cities in Norway. Findings from feature selection reveal a correlation between rising heating degree days and heightened air pollution levels, suggesting increased heating activities in Norway are a contributing factor to worsening air quality. PBDL demonstrates superior accuracy in air pollution predictions compared to LSTM. This paper contributes to the growing literature on PBDL methods for more accurate air pollution predictions using environmental variables, aiding policymakers in formulating effective data-driven climate policies.

WEF Maritime Hub to Drive Fourth Industrial Revolution - Port Technology International

#artificialintelligence

The Aker group and the World Economic Forum (WEF) will develop what they call the Centre for the Fourth Industrial Revolution Norway (C4IR Norway), as part of efforts to preserve the ocean through advanced technology. Through the partnerships, the Centre aims to develop governance frameworks and solutions for a sustainable and profitable ocean economy, using digital technology ranging from Artificial Intelligence (AI) to Blockchain. The Centre will provide a platform for partnerships on governance policies, research and business solutions that can stimulate the application of science, data and technology in the public interest. The C4IR Norway will join the WEF's global C4IR Network and collaborate with the Government of Norway and the High Level Panel for a Sustainable Ocean Economy. The Centre will be an independent non-profit foundation, financed initially by founding partner the Aker group.
