- Abstract summary: We propose to use a Transformer-based model to process electrocardiograms (ECG) for emotion recognition.
To overcome the relatively small size of datasets with emotional labels, we employ self-supervised learning.
We show that our approach reaches state-of-the-art performances for emotion recognition using ECG signals on AMIGOS.

- Abstract: In order to exploit representations of time-series signals, such as
physiological signals, it is essential that these representations capture
relevant information from the whole signal. In this work, we propose to use a
Transformer-based model to process electrocardiograms (ECG) for emotion
recognition. Attention mechanisms of the Transformer can be used to build
contextualized representations for a signal, giving more importance to relevant
parts. These representations may then be processed with a fully-connected
network to predict emotions. To overcome the relatively small size of datasets
with emotional labels, we employ self-supervised learning. We gathered several
ECG datasets with no labels of emotion to pre-train our model, which we then
fine-tuned for emotion recognition on the AMIGOS dataset. We show that our
approach reaches state-of-the-art performances for emotion recognition using
ECG signals on AMIGOS. More generally, our experiments show that transformers
and pre-training are promising strategies for emotion recognition with
physiological signals.

This study aims to understand and improve the predictive accuracy of emotional state classification by applying a Long Short-Term Memory (LSTM) network to analyze EEG signals.
Using a popular dataset of multi-channel EEG recordings known as DEAP, we look towards leveraging LSTM networks' properties to handle temporal dependencies within EEG signal data.
We obtain accuracies of 89.89%, 90.33%, 90.70%, and 90.54% for arousal, valence, dominance, and likeness, respectively, demonstrating significant improvements in emotion recognition model capabilities.
