Supervised learning is characterized by the use of labeled data during the training process. In this approach, a model is provided with a dataset wherein each input data point is associated with a corresponding label or output value. The primary goal of supervised learning is to enable the model to learn the relationship between the input data and the known outputs so that it can make accurate predictions on new, unseen data.

The presence of labeled data is crucial, as it guides the learning process, allowing the model to adjust its parameters based on the error between the predicted output and the actual labels. This forms the basis for various supervised learning tasks such as classification and regression, where the model learns to distinguish between different classes or predict continuous value outputs, respectively.

In contrast, the other options refer to different types of learning methodologies. For instance, training without any data is impractical and does not contribute to a learning process. Similarly, training with unlabeled data pertains to unsupervised learning, where patterns or structures are found without predefined labels. Reinforcement learning, on the other hand, involves learning through interactions with an environment and receiving feedback in the form of rewards or penalties, which differs fundamentally from the supervised learning approach that relies on explicit labels. Hence, the definition that emphasizes model
