can you write the following sentences in better way?: Reinforcement learning is one of the machine learning approaches in which an agent tries to improve its decisions based on interactions with the environment by receiving feedbacks from the results of its decisions in the environment. The main framework of reinforcement learning consists of two components: an agent and its environment. The output of the interactions between the agent and the environment is created in a repetitive cyclical process, a sequence of states, actions and rewards as shown in Figure 1. According to this framework, an intelligent agent performs an action a_t concerning the current state at time t (s_t ) and receives a reward r_(t+1) as a result of the performed action. Then, the agent observes a new state s_(t+1) and performs the next action based on the new state. This iterative framework continues until the agent converges to an optimal policy by maximizing a notion of cumulative reward.
What is Reinforcement Learning? Reinforcement learning is an area of machine learning in which an agent learns how to interact with its environment in order to maximize a notion of cumulative reward. It is based on a feedback loop of
