Aprendizado em Políticas Aprendizado por Reforço is a subfield of reinforcement learning where an agent learns to make decisions by following the current policy and using the data generated from its own actions. This means that the agent only improves its policy based on the experiences it gathers while interacting with the environment de acordo com essa própria política.
In on-policy methods, the agent explores the environment and exploits its current knowledge simultaneously. The learning process involves updating the policy based on the feedback received from the actions taken. A common example of on-policy reinforcement learning is the Gradiente de Política methods, where the agent directly adjusts the policy parameters para maximizar as recompensas esperadas.
Uma das principais vantagens de aprendizado on-policy is that it allows for a more stable learning process, as the agent is continually refining its understanding of the environment based on its current policy. However, this approach can be less efficient compared to off-policy methods, which can learn from actions taken by other policies, allowing for greater exploration do espaço de ações.
Overall, on-policy reinforcement learning is crucial for tasks where the agent must adapt its strategy based on its ongoing experiences, making it a fundamental concept in the campo de inteligência artificial e aprendizado de máquina.
