New Paper “Deep learning enhanced road traffic analysis”
A recent study has demonstrated a novel approach to the large-scale monitoring of road traffic. Rather than relying on radar or mobile sensors, the team used PlanetScope’s Super Dove satellite imagery to detect moving vehicles and estimate their speed. By implementing a Keypoint R-CNN learning model, the researchers were able to track the subtle “motion…

New Paper “How politics affect pandemic forecasting”
Searching for early warning systems during the COVID-19 pandemic, the researchers explored how digital data sources such as geo-social media (e.g. posts on platforms like X, formerly Twitter, that include location data) could improve the disease’s transmission dynamics. This data offers a valuable tool for local event detection. The study investigated how geo-social media topics…
