Precise localization within the GI tract by combining classification of CNNs and time-series analysis of HMMs

no code implementations11 Oct 2023 Julia Werner, Christoph Gerum, Moritz Reiber, Jörg Nick, Oliver Bringmann

This paper presents a method to efficiently classify the gastroenterologic section of images derived from Video Capsule Endoscopy (VCE) studies by exploring the combination of a Convolutional Neural Network (CNN) for classification with the time-series analysis properties of a Hidden Markov Model (HMM).

The Rank-Reduced Kalman Filter: Approximate Dynamical-Low-Rank Filtering In High Dimensions

2 code implementations NeurIPS 2023 Jonathan Schmidt, Philipp Hennig, Jörg Nick, Filip Tronarp

In this paper, we propose a novel approximate Gaussian filtering and smoothing method which propagates low-rank approximations of the covariance matrices.
