Noise Sensitivity and Stability of Deep Neural Networks for Binary Classification

no code implementations18 Aug 2023 Johan Jonasson, Jeffrey E. Steif, Olof Zetterqvist

A first step is taken towards understanding often observed non-robustness phenomena of deep neural net (DNN) classifiers.

Robust Neural Network Classification via Double Regularization

no code implementations15 Dec 2021 Olof Zetterqvist, Rebecka Jörnsten, Johan Jonasson

Here we propose a novel double regularization of the neural network training loss that combines a penalty on the complexity of the classification model and an optimal reweighting of training observations.

Bayesian leave-one-out cross-validation for large data

no code implementations24 Apr 2019 Måns Magnusson, Michael Riis Andersen, Johan Jonasson, Aki Vehtari

Model inference, such as model comparison, model checking, and model selection, is an important part of model development.

Model Selection

Fast mixing for Latent Dirichlet allocation

no code implementations11 Jan 2017 Johan Jonasson

Then one samples from the given distribution by running the Markov chain for a "long time" until it appears to be stationary and then collects the sample.
