Some common algorithms used in supervised learning include:
1. Linear Regression: This algorithm is used for predicting continuous outcomes. For example, predicting housing prices based on various features like size and location.
2. Logistic Regression: Despite its name, logistic regression is used for binary classification problems. An example would be determining whether an email is spam or not based on certain features.
3. Decision Trees: This algorithm splits data based on feature values to create a model in the form of a tree structure. A practical application could be a loan approval system that uses applicant features to decide approval.
4. Random Forest: This is an ensemble method that uses multiple decision trees to improve classification accuracy. It can be used for both classification and regression tasks, such as predicting customer churn.
5. Support Vector Machines (SVM): SVMs are powerful for both linear and non-linear classification problems. An example is image classification, where the algorithm separates different categories of images based on pixel values.
6. k-Nearest Neighbors (k-NN): This algorithm classifies data points based on the classes of their nearest neighbors. It’s often used in recommendation systems, such as suggesting movies based on user preferences.
7. Neural Networks: A powerful technique for modeling complex relationships in large datasets, often used in applications like image recognition and natural language processing.
These algorithms can be selected based on the nature of the data, the problem at hand, and the performance metrics of interest.
