Thanks for your replay. Well, what are the preprocessing of data annotation before training and what is the range of normalization, because I see negative numbers in the annotation of pedestrian coordinates

Well, the origin of the data and it's processing comes from Social-LSTM /Social-GAN you can check them for more details. The normalization is simply a delta between steps, this is why you see -ve values.
