Partha Maji, Principal Research Scientist at Arm’s Machine Learning Research Lab, presents the “Robust Object Detection Under Dataset Shifts” tutorial at the May 2021 Embedded Vision Summit.

In image classification tasks, the evaluation of models’ robustness to increased dataset shifts with a probabilistic framework is very well studied. However, object detection (OD) tasks pose other challenges for uncertainty estimation and evaluation. For example, one needs to evaluate both the quality of the label uncertainty (i.e., what?) and spatial uncertainty (i.e., where?) for a given bounding box, but that evaluation cannot be performed with more traditional average precision metrics (e.g., mAP).

In this talk, Maji discusses how to adapt well-established object detection models to generate uncertainty estimations by introducing stochasticity in the form of Monte Carlo Dropout (MC-Drop). He also discusses how such techniques could be extended to a broad class of embedded vision tasks to improve robustness.
