see 17 Robot intensive learning thesis in , When adopting imitation learning , Some papers present data in the first person , Some papers use the third person to demonstrate the data , First person and third person , I think it describes the position of the camera .

stay THIRD-PERSON IMITATION LEARNING The explanation is mentioned in this paper ：
first person ：the agent is provided with a sequence of states and a specification of the actions that it should have taken.
third person ：they observe other humans perform tasks, infer the task, and accomplish the same task themselves.

informally ： The first person is to see their own demonstration , Demonstrate observations and... In the trajectory action Same as when testing ; The third person is to watch others demonstrate , Demonstrate observations and... In the trajectory action Need to switch to the first person .
