Supervised learning is a fundamental approach in machine learning where models are trained on labeled datasets. In this context, labeled data refers to input-output pairs where the input data is accompanied by the correct output or target that the model is expected to predict. This method allows the model to learn the relationship between the input features and the corresponding labels, which is crucial for making predictions on unseen data.

During the training process, the model utilizes the labeled examples to identify patterns and correlations in the data, effectively "supervising" its learning through the guidance provided by the labels. Once trained, the model can generalize its knowledge to make predictions for new, unlabeled instances based on what it has learned.

In supervised learning, the performance of the model is typically assessed using metrics that evaluate how accurately it predicts the output for a validation dataset, which also contains labeled examples. This approach is widely used in applications such as classification tasks, where the outcomes are discrete categories, and regression tasks, where the outcomes are continuous values.
