- W4313530102 abstract "Accurate human trajectory prediction is still challenging due to the complicated interactions with surroundings. A Spatio-Temporal Graph Convolution Neural Network based Social Interaction Model (STGCNN-SIM) is proposed to address this challenge. In addition to historical trajectory information, the presented method employs the speculated trajectories in the future to extract social interactive features and model interaction behaviors. Three social interactive features are extracted explicitly from the observed and speculated trajectories: (1) the relative distance, (2) the angle between the velocity vectors of two interacting partners, and (3) the angles between the velocity vectors of interacting partners and the distance vector. STGCNN-SIM utilizes these social interactive features to model interactions with surroundings in the historical and speculated stages. Then an attention mechanism is adopted to improve the model by focusing on more relevant features. Experimental results on three public datasets demonstrate that STGCNN-SIM achieves higher accuracy and stability than the state-of-the-art methods." @default.
