Hello author, in your public dataset, the feature dimension of each node in each dataset is 2. It can be seen that the 0th dimension represents speed, so what data does the 1st dimension represent? Its range of values is [0,1.] . When predicting, only the speed was predicted, without considering dimension 1.
