Researchers have developed a novel method to decompose predictive variance in deep twin networks, separating it into encoder and head components. This technique, which adds minimal computational cost, helps pinpoint the source of model failures. The encoder component proves crucial for identifying out-of-distribution samples under covariate shift, while the head component becomes informative only after encoder uncertainty is managed. This decomposition offers a practical diagnostic tool for guiding data collection strategies. AI
