Triaging patients with artificial intelligence for respiratory symptoms in primary care to improve patient outcomes: a retrospective diagnostic accuracy study

S Ellertsson, HD Hlynsson, H Loftsson… - The Annals of Family …, 2023 - Annals Family Med
PURPOSE Respiratory symptoms are the most common presenting complaint in primary
care. Often these symptoms are self resolving, but they can indicate a severe illness. With …

Semi-self-supervised automated ICD coding

HD Hlynsson, S Ellertsson, JF Daðason… - arXiv preprint arXiv …, 2022 - arxiv.org
Clinical Text Notes (CTNs) contain physicians' reasoning process, written in an unstructured
free text format, as they examine and interview patients. In recent years, several studies …

Measuring the data efficiency of deep learning methods

HD Hlynsson, L Wiskott - arXiv preprint arXiv:1907.02549, 2019 - arxiv.org
In this paper, we propose a new experimental protocol and use it to benchmark the data
efficiency --- performance as a function of training set size --- of two deep learning algorithms, …

Gradient-based training of slow feature analysis by differentiable approximate whitening

M Schüler, HD Hlynsson… - Asian Conference on …, 2019 - proceedings.mlr.press
We propose Power Slow Feature Analysis, a gradient-based method to extract temporally
slow features from a high-dimensional input stream that varies on a faster time-scale, as a …

Reward prediction for representation learning and reward shaping

HD Hlynsson, L Wiskott - arXiv preprint arXiv:2105.03172, 2021 - arxiv.org
… It is generally not true that the distance function d and all … d were computable, using it naïvely
can bring about its own problems as was alluded to above. We argue that instead of using d

Learning gradient-based ICA by neurally estimating mutual information

HD Hlynsson, L Wiskott - KI 2019: Advances in Artificial Intelligence: 42nd …, 2019 - Springer
Several methods of estimating the mutual information of random variables have been developed
in recent years. They can prove valuable for novel approaches to learning statistically …

Visual processing in context of reinforcement learning

HD Hlynsson - arXiv preprint arXiv:2208.12525, 2022 - arxiv.org
… in a supervised fashion from a data set of observed transitions, D = {(st,at,rt,st+1)i}. The
world models can be used in multiple different ways, depending on the algorithm, to derive the …

[PDF][PDF] Reduction of Variance-related Error through Ensembling: Deep Double Descent and Out-of-Distribution Generalization.

P Rath-Manakidis, HD Hlynsson, L Wiskott - ICPRAM, 2022 - scitepress.org
Prediction variance on unseen data harms the generalization performance of deep neural
network classifiers. We assess the utility of forming ensembles of deep neural networks in the …

EfferenceNets for latent space planning

HD Hlynsson, M Schüler, R Schiewer, L Wiskott - 2019 - openreview.net
Planning in high-dimensional space remains a challenging problem, even with recent advances
in algorithms and computational power. We are inspired by efference copy and sensory …
