What distinguishes supervised learning from unsupervised learning?

Supervised learning is characterized by its reliance on labeled data. In this approach, the model is trained using a dataset that includes input-output pairs, where the output (or label) is known. This allows the model to learn the relationship between the input features and the correct output, enabling it to make predictions or classifications on new, unseen data.

In contrast, unsupervised learning does not use labeled data. Instead, it seeks to identify patterns and structures in the input data without any explicit instructions on what to look for. This could involve clustering similar data points together or reducing the dimensionality of data. The absence of labels in unsupervised learning means that the algorithm must discern underlying patterns purely from the data itself.

The other options do not accurately describe the fundamental differences between these two types of learning methodologies. For example, the speed of processing in supervised versus unsupervised learning is not inherently due to the type of learning, and while supervised learning can be used for image classification, it is not limited to it; the same goes for unsupervised learning and text. Lastly, stating that both methods are the same ignores their distinct characteristics and applications. Thus, the unique reliance of supervised learning on labeled data sets it apart from unsupervised
