“So that type of very high resolution, complex, you know, patterns of precipitation, for example, Wind as well. Those are much harder to predict because you're effectively predicting a lot more information. You can't just sort of summarize it by saying, oh, every, you know, 25 kilometers or whatever, the temperature is this, and then everything else is just kind of interpolated in between. You have a lot of stuff happening at a much finer scale than a lot of our models even capture, and then we have to do a secondary step to try to resolve those finer details.”

Battaglia: Data pipelines matter more than neural network architectures today
“I don't feel that neural network architectures these days tend to be the sort of exciting part. It's usually more of like the training and the sort of data how you handle the data and that kind of thing.”
DeepMind uses transformers to model spatial interactions in weather, not time
“We actually use transformers not to model the spatial, the interactions in weather over time, like the sequence of text, but in space.”
Battaglia: AI weather models leverage macroscopic spatial ranges unlike traditional simulations
“In a traditional model, the way it simulates that is it, in very fine detail, it kind of figures out, like, what's the pressure, and the temperature, and the wind, and the moisture, and what are those things? What's going to happen next is determined strictly …”
DeepMind primarily uses traditional supervised learning for AI weather models
“What we use in our weather forecasting models, and a lot of folks out in the community are using it as, you know, as this field is advancing and this AI-based weather forecasting is developing, we're still mostly using fairly traditional machine learning, supe…”
Battaglia: Early ML in weather improved downstream calibration, not base models
“So actually, the first advent of like, AI and machine learning in weather forecasting, or at least some of the earliest, was not, like, trying to overhaul the whole weather forecast process itself, but making, you know, using more and more, like, statistical m…”
