Trajectory forecasting is a sequential prediction task, where a forecasting model predicts future trajectories of all moving agents (humans, vehicles, etc.) in a scene, based on their past trajectories and/or the scene context.

A recurrent sequence-to-sequence model observes motion histories and predicts future behavior, using a novel pooling mechanism to aggregate information across people, and outperforms prior work in terms of accuracy, variety, collision avoidance, and computational complexity.
Trajectron++ is a modular, graph-structured recurrent model that forecasts the trajectories of a general number of diverse agents while incorporating agent dynamics and heterogeneous data and outperforming a wide array of state-of-the-art deterministic and generative methods.
DILATE (DIstortion Loss including shApe and TimE), a new objective function for training deep neural networks that aims at accurately predicting sudden changes, is introduced, and explicitly incorporates two terms supporting precise shape and temporal change detection.
This work intro-duce a social contrastive loss that regularizes the extracted motion representation by discerning the ground-truth positive events from synthetic negative ones, and constructs informative negative samples based on the prior knowledge of rare but dangerous circumstances.
Argoverse includes sensor data collected by a fleet of autonomous vehicles in Pittsburgh and Miami as well as 3D tracking annotations, 300k extracted interesting vehicle trajectories, and rich semantic maps, which contain rich geometric and semantic metadata which are not currently available in any public dataset.
This work presents Predicted Endpoint Conditioned Network (PECNet) for flexible human trajectory prediction, which improves state-of-the-art performance on the Stanford Drone trajectory prediction benchmark and on the ETH/UCY benchmark by ~40.8%.
An end-to-end, multi-task learning system utilizing rich visual features about human behavioral information and interaction with their surroundings is proposed, providing the first empirical evidence that joint modeling of paths and activities benefits future path prediction.
The Social Spatio-Temporal Graph Convolutional Neural Network (Social-STGCNN), which substitutes the need of aggregation methods by modeling the interactions as a graph, and is data efficient, and exceeds previous state of the art on the ADE metric with only 20% of the training data.
This paper addresses the question of evaluating how complex is a given dataset with respect to the prediction problem by defining a series of indicators around three concepts: Trajectory predictability;Trajectory regularity; Context complexity.
In this paper, a novel framework, named Dynamic Context Encoder Network (DCENet), the spatial context between agents is explored by using self-attention architectures, and a set of future trajectories for each agent is predicted conditioned on the learned spatial-temporal context by sampling from the latent space.
Adding a benchmark result helps the community track progress.
