Supervised Learning: A Fundamental Concept in Machine Learning
Supervised learning is a type of machine learning where the algorithm learns from labeled data. In other words, it’s trained on examples that are already classified or categorized. This allows the model to learn the relationship between inputs and outputs, enabling it to make predictions on new, unseen data.
The goal of supervised learning is to develop an accurate prediction function based on a dataset containing input-output pairs. For instance, if you have a dataset of images labeled as either ‘dog’ or ‘cat’, your algorithm would learn to recognize the features that distinguish between these two classes and predict the correct label for new, unseen images.
Supervised learning has numerous applications in various fields, including image classification, speech recognition, sentiment analysis, and more. In fact, many AI-powered systems rely heavily on supervised learning techniques to make accurate predictions.
One of the most popular examples of supervised learning is facial recognition technology used by law enforcement agencies to identify suspects from surveillance footage. This technology relies on a large dataset of labeled images (faces with corresponding identities) to train its algorithm and recognize faces in real-time.
