Estimation of safe area using trajectory prediction of other vehicles in an intersection scene.

Inverse reinforcement learning is used to predict the trajectories of other vehicles and humans.
By using a nonparametric bayesian-based algorithm as an elemental technology, the following advantages can be realized.

  • Predictions close to human senses are possible
  • Requires less training data than conventional DeepLearning or probabilistic models
  • Can be processed by edge devices
  • Possible to analyze what is used to output inference results
  • No need for humans to provide parameters; the model itself makes the decision
