uncertain-classifier

An image classifier that quantifies its uncertainty using Bayesian methods as described in Kendall and Gal (2017)

Epistemic uncertainty

  • Model is confused between two or more classes, i.e. the image is a digit but it's not clear which one.
  • Can be fixed with more data.

Aleatoric uncertainty

  • Data is out-of-domain or the data is noisy.
  • Cannot be fixed with more data

Epistemic model

$ python3 train.py epistemic
$ python3 vis.py epistemic

Aleatoric model

$ python3 train.py aleatoric
$ python3 vis.py aleatoric

Combined model

$ python3 train.py combined
$ python3 vis.py combined
