 This dataset serves as a supplement to the Physion dominoes dataset we generated, addressing some issues in the original Physion dataset that could lead to trivial model training, such as dominoes having only one toppling direction, and unique markers at the start and end points. Our dataset focuses more on collisions and offers greater diversity.
