Forecasting Future Trajectories with an Improved Transformer Network

چکیده
An increase in car ownership brings convenience to people’s life. However, it also leads frequent traffic accidents. Precisely forecasting surrounding agents’ future trajectories could effectively decrease vehicle-vehicle and vehicle-pedestrian collisions. Long-short-term memory (LSTM) network is often used for vehicle trajectory prediction, but has some shortages such as gradient explosion low efficiency. A prediction method based on an improved Transformer proposed forecast a complex environment. It realizes the transformation from sequential step processing of LSTM parallel attention mechanism. To perform more efficiently, probabilistic sparse self-attention mechanism introduced reduce complexity by reducing number queried values Activate or not (ACON) activation function adopted select whether activate not, hence improving model flexibility. The evaluated publicly available benchmarks next-generation simulation (NGSIM) ETH/UCY. experimental results indicate that can accurately efficiently predict trajectories.

A sigmoid function is necessary for creation a chaotic neural network (CNN). In this paper, a new function for CNN is proposed that it can increase the speed of convergence. In the proposed method, we use a novel signal for controlling chaos. Both the theory analysis and computer simulation results show that the performance of CNN can be improved remarkably by using our method. By means of this...
