Sparse-Denoising Methods for Extracting Desaturation Transients in Cerebral Oxygenation Signals of Preterm Infants

no code implementations20 Aug 2021 Minoo Ashoori, Eugene M. Dempsey, Fiona B. McDonald, John M. O'Toole

Our analysis, using a synthetic NIRS-like dataset, showed that a LPF_TVD method outperformed the modified SSA_DCT method: median mean-squared error of 0. 97 (95% CI: 0. 86 to 1. 07) was lower for the LPF_TVD method compared to the modified SSA_DCT method of 1. 48 (95% CI: 1. 33 to 1. 63), P<0. 001.

Tracé alternant detector for grading hypoxic-ischemic encephalopathy in neonatal EEG

no code implementations31 May 2021 Sumit A. Raurale, Geraldine B. Boylan, Sean R. Mathieson, William P. Marnane, Gordon Lightbody, John M. O'Toole

These results validate how detecting the presence or absence of TA can be used to quantify the grade of HIE injury in neonatal EEG and open up the possibility of a clinically-meaningful grading system.

Grading the severity of hypoxic-ischemic encephalopathy in newborn EEG using a convolutional neural network

no code implementations12 May 2020 Sumit A. Raurale, Geraldine B. Boylan, Gordon Lightbody, John M. O'Toole

Electroencephalography (EEG) is a valuable clinical tool for grading injury caused by lack of blood and oxygen to the brain during birth.

Identifying trace alternant activity in neonatal EEG using an inter-burst detection approach

no code implementations12 May 2020 Sumit A. Raurale, Geraldine B. Boylan, Gordon Lightbody, John M. O'Toole

This study presents a novel approach for detecting TA activity by first detecting the inter-bursts and then processing the temporal map of the bursts and inter-bursts.

Machine learning without a feature set for detecting bursts in the EEG of preterm infants

no code implementations16 Jul 2019 John M. O'Toole, Geraldine B. Boylan

Deep neural networks enable learning directly on the data without the domain knowledge needed to construct a feature set.
