Before revision:  Our protocol gives rise to a new family of interactive learning algorithms that offer complementary advantages against traditional algorithms like imitation learning (IL) and reinforcement learning (RL)  . We develop  an algorithm that practically implements this protocoland employ it to train agents in two challenging request-fulfilling problems using purely language-description feedback.
After revision:  Our protocol gives rise to a new family of interactive learning algorithms that offer complementary advantages against traditional algorithms like imitation learning (IL) , our protocol allows the teaching agent to provide feedback in a language that is most appropriate for them. Compared with reward in reinforcement learning (RL) . We develop an algorithm that practically implements this protocoland employ it to train agents in two challenging request-fulfilling problems using purely language-description feedback.
