Google’s DeepMind team released a new AI model for weather forecasting this week called GenCast.
In a Nature articleDeepMind researchers found that GenCast was superior to the European Centre for Medium-Range Weather Forecasts ENS, which is the world’s best operational forecasting system.
In addition, in In a blogthe DeepMind team explained the technology in a more understandable way: While its previous model was “deterministic” and provided a “single, best estimate of weather in the future, GenCast is “an ensemble of 50 or so predictions, each representing a potential weather trajectory,” creating a complex probability distribution of future scenarios.
To compare GenCast to ENS, they said that it was trained on weather data from 2018 then compared with ENS, and ENS, then compared the forecasts, they compared the team,
