1D-Convolutional transformer for Parkinson disease diagnosis from gait

1 code implementation6 Nov 2023 Safwen Naimi, Wassim Bouachir, Guillaume-Alexandre Bilodeau

Our experimental results show that our approach is effective for detecting the different stages of Parkinson's disease from gait data, with a final accuracy of 88%, outperforming other state-of-the-art AI methods on the Physionet gait dataset.

Automating lichen monitoring in ecological studies using instance segmentation of time-lapse images

no code implementations26 Oct 2023 Safwen Naimi, Olfa Koubaa, Wassim Bouachir, Guillaume-Alexandre Bilodeau, Gregory Jeddore, Patricia Baines, David Correia, Andre Arsenault

These cameras are used by ecologists in Newfoundland and Labrador to subsequently analyze and manually segment the images to determine lichen thalli condition and change.
