Yarin Gal disagrees with the accepted answer: "by the way, using softmax to get probabilities is actually not enough to obtain model uncertainty" "This is because the standard model would pass the predictive mean through the softmax rather than the entire distribution. Types of Uncertainty Source: Uncertainty in Deep Learning (Yarin Gal, 2016) Aleatoric uncertainty (stochastic, irreducible) = uncertainty in data (noise) → more data doesn't help "Aleatoric" → Latin "aleator" = "dice player's" Can be further divided: Homoscedastic → uncertainty is same for all inputs Heteroscedastic → observation.

Our model generalises well to unseen images and requires a single forward pass to perform saliency detection, therefore suitable for use in real-time systems. Machine learning techniques have been successfully applied to super-resolution tasks on natural images where visually pleasing results are sufficient. I will go over a few of the commonly used approaches to exploration which focus on….
