The snowpack is now being asked to file its own stability report
the snowpack is now being asked to file its own stability report: a model trained on forecast and weather station data helps decide avalanche danger ratings at a backcountry forecast zone, an avalanche warning system built on deep learning rolls 72 hour risk outlooks down to individual gullies, and autoencoder features push avalanche recall from 0.67 to 0.71.
the mountain now files its own release log.
Context
The autoencoder result in the note matches a Geoscientific Model Development paper on autoencoder-based feature extraction for automatic detection of snow avalanches in seismic data. Classifiers reached an avalanche recall of 0.67 with expert-engineered seismic attributes, 0.71 with temporal autoencoder features and 0.70 with spectral autoencoder features.
For danger ratings, several Swiss studies train models on weather station and snow data, including a three-stage pipeline for regional avalanche danger (RAvaFcast) and a neural network for automated prediction of the danger level. Their data come from the Swiss avalanche warning service.
The recall figures come from detecting avalanches in seismic signals. The danger rating models forecast the level for a region. They answer different questions, one about what already released and one about what may release.
