• Authors: Isht Dwivedi, Srikanth Malla, Behzad Dariush, Chiho Choi
• Abstract summary: We propose a robust solution to future trajectory forecast, which can be practically applicable to autonomous agents in highly crowded environments. First, we use composite fields to predict future locations of all road agents in a single-shot, which results in a constant time. Second, interactions between agents are modeled as non-local, response enabling spatial relationships between different locations to be captured temporally. Third, the semantic context of the scene are modeled and take into account the environmental constraints that potentially influence the future motion.

• Abstract: We propose a robust solution to future trajectory forecast, which can be practically applicable to autonomous agents in highly crowded environments. For this, three aspects are particularly addressed in this paper. First, we use composite fields to predict future locations of all road agents in a single-shot, which results in a constant time complexity, regardless of the number of agents in the scene. Second, interactions between agents are modeled as a non-local response, enabling spatial relationships between different locations to be captured temporally as well (i.e., in spatio-temporal interactions). Third, the semantic context of the scene are modeled and take into account the environmental constraints that potentially influence the future motion. To this end, we validate the robustness of the proposed approach using the ETH, UCY, and SDD datasets and highlight its practical functionality compared to the current state-of-the-art methods.

  We introduce the GPT style next token motion prediction into motion prediction. Different from language data which is composed of homogeneous units -words, the elements in the driving scene could have complex spatial-temporal and semantic relations. We propose to adopt three factorized attention modules with different neighbors for information aggregation and different position encoding styles to capture their relations.
