Rice University engineers have developed a computer system that used deep learning to teach itself to accurately predict extreme weather events like heat waves and cold spells, based on a minimal amount of weather data.

Rice's capsule neural network studied hundreds of pairs of maps during training, with each map displaying surface temperatures and air pressures at five-kilometer elevations, several days apart. After training, the network could examine previously unseen maps and produce five-day extreme weather projections with 85% accuracy.

The researchers think the network eventually could function as an early warning system for weather forecasters, as well as a tool for learning more about the atmospheric precursors of extreme weather.
