What are Support Vector Machines?

February 4, 2023

Support Vector Machines (SVMs) are a type of machine learning algorithm that can be used for both regression and classification problems. They are a popular tool for business and financial applications due to their ability to handle large and complex datasets, and to accurately predict outcomes in a variety of situations.

SVMs are designed to maximize the margin between the different classes in a dataset. This is achieved by finding the best line, or hyperplane, that separates the classes. The hyperplane is chosen based on the data points that are closest to it, called support vectors, hence the name Support Vector Machines. These support vectors determine the position and orientation of the hyperplane.

One of the key benefits of SVMs is their ability to handle non-linear relationships in the data. This is done by transforming the data into a higher-dimensional space, where a linear boundary can be found to separate the classes. This allows for greater accuracy in prediction, particularly when dealing with complex datasets.

Another advantage of SVMs is their ability to handle high-dimensional data, such as images or text. This is important for businesses, as it allows them to make predictions using a large number of features, or variables, without sacrificing accuracy.

SVMs also have a number of tuning parameters that can be adjusted to optimize performance. These parameters include the type of kernel used, the cost of misclassification, and the regularization parameter. By carefully selecting these parameters, businesses can optimize the performance of their SVM to best suit their specific needs.

Support Vector Machines are a powerful and versatile tool for machine learning. Their ability to handle complex and high-dimensional data, and their flexibility in terms of tuning parameters, make them a valuable tool for businesses looking to make accurate predictions and improve their decision-making processes.
