Master Thesis: Uncertainty Estimation for Segmentation in Autonomous Driving
In the context of Autonomous Driving, it is crucial to have a measure of the uncertainty associated to the various predictions performed by the Deep Learning models. This helps not only to combine various predictions from different pipelines, but also to understand the real confidence associated to each prediction. Networks tend to be overly confident (~99%, as derived from the logits probabilities) also on wrong predictions, or rather unknown data and scenarios. This makes such confidence unreliable. Therefore, uncertainty estimation complements predictions by quantifying how certain the models really are, with respect to the inputs, or their own weights and the way they were trained.
Among the fundamental tasks of Autonomous Driving there is segmentation (semantic segmentation, instance segmentation, panoptic segmentation, part segmentation...), which is where we would like to integrate uncertainty estimation with this work.
This Master Thesis will be done in cooperation with BMW.
