EEG to fMRI Synthesis Benefits from Attentional Graphs of Electrode Relationships

no code implementations7 Mar 2022 David Calhas, Rui Henriques

In addition, we observe that haemodynamic activity at the scalp, in contrast with sub-cortical regions, is relevant to the learned shared space.

Automatic Generation of Neural Architecture Search Spaces

1 code implementation AAAI Workshop CLeaR 2022 David Calhas, Vasco M. Manquinho, Ines Lynce

Here, we propose a framework that encodes the structure of a convolutional neural network, respecting the arithmetical relation of the kernel and stride sizes with the input and output shapes.

Fitting Regularized Population Dynamics with Neural Differential Equations

no code implementations NeurIPS Workshop DLDE 2021 David Calhas, Rui Henriques

Neural differential equations (neural DEs) are yet to see success in its application as interpretable autoencoders/descriptors, where they directly model a population of signals with the learned vector field.

EEG to fMRI Synthesis: Is Deep Learning a candidate?

no code implementations29 Sep 2020 David Calhas, Rui Henriques

EEG to fMRI synthesis offers a way to enhance and augment brain image data, and guarantee access to more affordable, portable and long-lasting protocols of brain activity monitoring.

On the use of Pairwise Distance Learning for Brain Signal Classification with Limited Observations

1 code implementation5 Jun 2019 David Calhas, Enrique Romero, Rui Henriques

The increasing access to brain signal data using electroencephalography creates new opportunities to study electrophysiological brain activity and perform ambulatory diagnoses of neuronal diseases.
