These neural networks consist of layers of interconnected nodes that process and analyze data, allowing the system to identify patterns and make predictions based on past experience.

To train the machine learning algorithms used in HyperMotion2, EA Sports used a large dataset of football matches captured with advanced motion-capture technology.

The dataset includes thousands of hours of footage, which was carefully analyzed and labeled by a team of experts to ensure the accuracy of the data.

In the case of HyperMotion2, backpropagation is used to adjust the parameters of the neural network to ensure that the in-game animations accurately replicate the movements of real-life players.

The mode also contains each of the 32 teams that qualified for the 2022 tournament, along with fifteen other national teams that are featured in the game and did not qualify: Austria, China, Czech Republic, Finland, Hungary, Iceland, Italy, New Zealand, Northern Ireland, Norway, Republic of Ireland, Romania, Scotland, Sweden, and Ukraine.
