Reinforcement learning is a branch of machine learning where an agent learns to make decisions by interacting with an environment. The primary mechanism through which this learning occurs is trial and error, where the agent takes actions and receives feedback in the form of rewards or penalties based on those actions. Over time, the agent learns to associate certain actions with higher rewards, allowing it to optimize its behavior to achieve the best possible outcomes.

In contrast, learning from labeled data refers to supervised learning, where the model is trained using a dataset with input-output pairs. Identifying hidden patterns in data aligns more closely with unsupervised learning techniques, such as clustering or association. Using a dataset to predict outcomes typically describes regression or classification tasks in supervised learning, where the model has predefined labels to guide its learning process. Therefore, the essence of reinforcement learning lies in its exploratory nature, emphasizing the process of trial and error to improve decision-making over time.
