Overall, we show that our model can efficiently simulate emergency evacuation in complex environments with multiple room exits and obstacles where it is difficult to obtain an intuitive rule for fast evacuation.

A deep reinforcement learning model based on deterministic policy gradient for collective neural crest cell migration

no code implementations • 7 Jul 2020 • Yihao Zhang, Zhaojie Chai, Yubing Sun, George Lykotrafitis

Because of the different migration mechanisms of leader and follower neural crest cells, we train two types of agents (leaders and followers) to learn the collective cell migration behavior.
