Project
As humans, we naturally adapt our decisions based on how confident we are in our own perception and understanding. Analogously, trustworthy computer vision systems should express an appropriate level of uncertainty when making predictions, such that we can identify and understand their mistakes.
A large portion of research in computer vision is focused on pushing the boundaries of model performance, without addressing the question “are you sure?”. While deep neural networks (DNNs) continue to show unprecedented results across many image understanding problems, they cannot reliably express their uncertainty when faced with unfamiliar or ambiguous inputs.
The goal of this project is to develop methods for capturing uncertainty in DNNs to enable reliable failure detection or out-of-distribution detection for computer vision. The project also aims to explore how uncertainty can be used to improve a model’s predictions.
