Question about data input using BEV #21

Open tomnqduc opened 9 months ago

tomnqduc commented 9 months ago

Dear authors,

Based on the paper and code description, for the Bird Eye View, only position (x_t, y_t) is used as the input for the model. However, when I tried to re-run the code (ETH dataset), it seems to me that a state vector of dimension 6 is used instead of 2. Can you clarify what these inputs are? see https://github.com/umautobots/bidireaction-trajectory-prediction/blob/296a50126cd50a1d4a0395696a0567575c4d4df8/bitrap/modeling/bitrap_np.py#L202C1-L203C1

Thank you in advance

I found it out myself. They are position, velocity and acceleration.
