Supervised learning

Supervised learning is a process whereby a computer system is trained to recognize patterns in data. The system is “fed” a set of training data, which has been previously labeled with the correct answers. The system then looks for patterns in the data that match the known labels. Once the system has learned to recognize these patterns, it can then be applied to new data, in order to make predictions about the labels of that data.

Supervised learning is often contrasted with unsupervised learning, which is a process whereby the computer system is not given any training data, but instead must learn to recognize patterns on its own. However, it is also possible touse a hybrid of these two approaches, which is sometimes called semi-supervised learning.

Supervised learning is a powerful tool that can be used for a variety of tasks, such as classification, regression, and prediction. It has been successfully applied to many different domains, including image recognition, facial recognition, and natural language processing .

Sample Supervised Learning Algorithm

One of the most popular supervised learning algorithms is the Support Vector Machine (SVM). SVMs are a type of machine learning algorithm that can be used for both classification and regression tasks. SVMs work by finding a hyperplane that maximizes the margin between two classes. In other words, it finds a line (or plane) that best separates the data into two groups. Once the SVM has found this hyperplane, it can then be used to make predictions about new data points.

Other popular supervised learning algorithms include decision trees, random forests, and neural networks.

Tools for Supervised Learning

There are a number of different software packages that can be used for supervised learning. Some of the most popular include scikit-learn, TensorFlow, and Keras.

  • scikit-learn is a machine learning library for Python that includes a wide range of algorithms, including SVMs, decision trees, and neural networks.
  • TensorFlow is an open source library for machine learning that was developed by Google. It can be used for a variety of tasks, including classification and prediction.
  • Keras is a high-level API for creating deep learning models. It can be used with TensorFlow or other backends.
