This can render the current OOD detectors impermeable to inputs lying outside the training distribution but with the same semantic information (e. g. training class labels).

We show that CBDL is better at quantifying and disentangling different types of uncertainties than single BNNs, ensemble of BNNs, and Bayesian Model Averaging.

Next, using these memories we partition the state space into disjoint subsets and compute bounds that should be respected by the neural network in each subset.

Algorithm design of AT and its variants are focused on training models at a specified perturbation strength $\epsilon$ and only using the feedback from the performance of that $\epsilon$-robust model to improve the algorithm.

We propose a new method for classification which can improve robustness to distribution shifts, by combining expert knowledge about the ``high-level" structure of the data with standard classifiers.

We formulate expert intervention as allowing the agent to execute option templates before learning an implementation.

We demonstrate the effectiveness of the proposed approach for verification of NNs used in automated control as well as those used in classification.
