Credal Wrapper of Model Averaging for Uncertainty Estimation on Out-Of-Distribution Detection

no code implementations23 May 2024 Kaizheng Wang, Fabio Cuzzolin, Keivan Shariatmadar, David Moens, Hans Hallez

This paper presents an innovative approach, called credal wrapper, to formulating a credal set representation of model averaging for Bayesian neural networks (BNNs) and deep ensembles, capable of improving uncertainty estimation in classification tasks.

Eating Speed Measurement Using Wrist-Worn IMU Sensors in Free-Living Environments

no code implementations15 Dec 2023 Chunzhuo Wang, T. Sunil Kumar, Walter De Raedt, Guido Camps, Hans Hallez, Bart Vanrumste

Experimental results shows that the proposed approach achieves a mean absolute percentage error (MAPE) of 0. 110 and 0. 146 in the FD-I and FD-II datasets, respectively, showcasing the feasibility of automated eating speed measurement.

An introduction to optimization under uncertainty -- A short survey

no code implementations1 Dec 2022 Keivan Shariatmadar, Kaizheng Wang, Calvin R. Hubbard, Hans Hallez, David Moens

The goal of this survey paper is to briefly touch upon the state of the art in a variety of different methods and refer the reader to other literature for more in-depth treatments of the topics discussed here.
