Prescribed cyclone tracks harm neural ocean emulator performance

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the impact of using prescribed cyclone tracks as input for neural ocean emulators. The study found that this approach, while seemingly intuitive, actually degrades the emulator's performance in the Bay of Bengal. The neural networks learned an incorrect response to the rare signal of cyclone tracks, leading to worse forecasts compared to models that did not condition on cyclone data. Replacing the cyclone map with a no-storm map during inference improved forecast accuracy. AI

IMPACT Highlights a counter-intuitive finding in applying ML to scientific forecasting, suggesting careful consideration of input data frequency and its impact on model learning.

    Too Rare to Learn: Prescribed Cyclone Tracks Degrade a Bay of Bengal Ocean Emulator

    arXiv:2609.04635v1 Announce Type: new Abstract: Neural ocean emulators are being proposed for regional forecasting in cyclone-exposed coastal seas, and a natural design choice is to hand the network the cyclone as a prescribed input. We test that choice in the Bay of Bengal and f…
