+
+This repository contains all the models trained in the scientific article titled *"Unveiling the Human-like Similarities of Automatic Facial Expression Recognition: An Empirical Exploration through Explainable AI"*.
+
+To reproduce the results of the article, please refer to the Github project containing all code used: [https://github.com/Xavi3398/ekman_expressions](https://github.com/Xavi3398/ekman_expressions).
+
+
+## Datasets used for training:
+The datasets used were 5: CK+, BU-4DFE, JAFFE and WSEFEP, and FEGA. These are some examples from each class:
