Uncertainty in Deep Learning

Submitted May 7, 2018

How do you deal with uncertainty when making decisions? Presumably, you would collect more information to reduce the uncertainty before making a decision. Now, think about the outputs of deep learning models which can be used to make automated decisions. How will you get uncertainty estimates for these outputs? In this talk, we will focus on quantifying model uncertainty based on recent research and discuss potential applications of the uncertainty estimates.


Problem: Deep Neural Networks are powerful function approximators. However, it is well known that they are prone to overfitting and can be overconfident about their decisions.
- examples of overfitting

Solution: Bayesian approach: Discuss recent research that provides model uncertainty estimates of deep neural networks.
- bayesian neural nets
- weight uncertainty
- variational approximation

Applications of uncertainty estimates: Discuss the practical utility of the uncertainty estimates
- active learning
- exploration vs. exploitation
