Support vector machine - Quiz
- 1. A support vector machine (SVM) is a supervised machine learning algorithm that is commonly used for classification and regression tasks. The goal of SVM is to find the hyperplane that best separates the data points into different classes, with a clear margin between the classes. SVM works by mapping the input data into a high-dimensional feature space and finding the optimal hyperplane that maximizes the margin between the classes. This optimal hyperplane is found by solving an optimization problem that aims to minimize the classification error and maximize the margin. SVM is known for its ability to handle high-dimensional data and complex classification tasks. It is also effective in dealing with non-linear data by using kernel functions to map the data into a higher-dimensional space. SVM is widely used in various applications such as text classification, image recognition, and bioinformatics due to its flexibility, accuracy, and robustness.
