註釋The subset of machine learning algorithms known as supervised learning is an essential component that makes a substantial contribution to the resolution of a wide variety of problems that are associated with the study of artificial intelligence (AI). A dataset that has been labeled is given to the algorithm during the supervised learning phase. This dataset contains not only the input data but also the target labels that correlate to those data. Both sets of information are included. The objective of this activity is to construct a model or a mapping that is able to reliably predict the labels for data that has not yet been observed. There are a large number of algorithms that are commonly used for supervised learning, and each of these techniques has a number of benefits as well as some drawbacks. The technique known as linear regression, which is applied in situations involving continuous numerical data, is one method that is frequently used. Creating a linear link between the input features and the variable that you want to change is the method that is used to accomplish this goal. Logistic regression is often utilized when the objective is to categorize individual data points into a number of separate groups or classes. It constructs a model that calculates the probability that a certain data point belongs to a particular category. Decision trees are a type of general-purpose algorithm that can be put to use for a variety of different classification and regression-related projects. They do this by constructing a tree-like structure, where each leaf node represents a projected class or value and each inside node represents a decision that was taken based on a feature. In other words, each node in the structure represents a decision that was made. The performance of prediction tasks can be improved using ensemble methods such as Random Forests and Gradient Boosting. These methods work by combining many decision trees into a single model. They are especially useful when it comes to managing difficult datasets. Support Vector Machines, often known as SVMs, are useful tools for binary classification because they pinpoint the hyperplane that achieves the optimal margin between classes. Because of this, they are able to deliver satisfactory results whenever there is a noticeable divide between the classes.
