The article seems to conflate accuracy and recall: > AI-powered earthquake forecasting scores 70% accuracy > The AI accurately predicted 70% of earthquakes a week in advance, with 14 forecasts coming true within 200 miles of their estimated locations and matching their anticipated magnitudes. However, it issued eight false warnings and missed one earthquake. The precision was 14/(14+8) (64%) and recall was 14/(14+1) (93%) which means the F1 score was .756. The accuracy was 14/(14+8+1) (61%). I'm not sure where they got the 70% from, perhaps a different F metric. In any event, it's clear the author is confused about the terminology. |
