Convolutional Neural Networks for Neuroimaging in Parkinson's Disease: Is Preprocessing Needed?

no code implementations21 Nov 2023 Francisco J. Martinez-Murcia, Juan M. Górriz, Javier Ramírez, Andrés Ortiz

The results show that a sufficiently complex model such as our three-dimensional version of the ALEXNET can effectively account for spatial differences, achieving a diagnosis accuracy of 94. 1% with an area under the ROC curve of 0. 984.

Tiled sparse coding in eigenspaces for the COVID-19 diagnosis in chest X-ray images

no code implementations28 Jun 2021 Juan E. Arco, Andrés Ortiz, Javier Ramírez, Juan M Gorriz

In this work, we propose a classification framework based on sparse coding in order to identify the pneumonia patterns associated with different pathologies.
