• Abstract: We present a deterministic method to compute the Gaussian average of neural networks used in regression and classification. Our method is based on an equivalence between training with a particular regularized loss, and the expected values of Gaussian averages. We use this equivalence to certify models which perform well on clean data but are not robust to adversarial perturbations. In terms of certified accuracy and adversarial robustness, our method is comparable to known stochastic methods such as randomized smoothing, but requires only a single model evaluation during inference.

  In deep reinforcement learning, estimating the value function is essential to evaluate the quality of states and actions. A recent study suggested that the error distribution for training the value function is often skewed because of the properties of the Bellman operator. We proposed a method called Symmetric Q-learning, in which the synthetic noise generated from a zero-mean distribution is added to the target values to generate a Gaussian error distribution.

  Uncertainty quantification is a central challenge in reliable and trustworthy machine learning. We show a trade-off between classification accuracy and calibration, unveiling a double descent like behavior in the calibration curve of optimally regularized estimators. This is in contrast with the empirical Bayes method, which we show to be well calibrated in our setting despite the higher generalization error and overparametrization.

  One of the most common problems preventing the application of prediction models in the real world is lack of generalization. We propose novel methods that estimate uncertainty of particular predictions generated by a neural network classification model. The proposed methods infer the confidence of a particular prediction based on the distribution of the logit values corresponding to this prediction.
