Is this really an "AI" story?
Aren't existing weather forecasting models, already a form of "AI"?
I'm no AI/ML expert, but isn't the real story here is that a new model (like GPT-4.0) is better than the previous/existing model (GPT-3.5).
It's just grabs way more attention calling the new model "AI" (vs not referring to the old as such).
- mdpye 3y agoIt's an ML story. The article specifies that the current (now previous?) state of the art models are numerical, crunching vast equations representing atmospheric physics.
- surfmike 3y agoNo, existing models use more numerical methods. This is using a completely different approach. > GraphCast utilizes what researchers call a "graph neural network" machine-learning architecture, trained on over four decades of ECMWF's historical weather data. It processes the current and six-hour-old global atmospheric states, generating a 10-day forecast in about a minute on a Google TPU v4 cloud computer. Google's machine learning method contrasts with conventional numerical weather prediction methods that rely on supercomputers to process equations based on atmospheric physics, consuming significantly more time and energy.
