Nonlinear SVMs
SVMs, and also a number of other linear classifiers, provide an easy and efficient way of doing this mapping to a higher dimensional space, which is referred to as ``the kernel trick ''. It's not really a trick: it just exploits the math that we have seen. The SVM linear classifier relies on a dot product between data point vectors.

Linear SVM: It is used when the data follows the linear separation behavior and can be classified into two classes. Nonlinear SVM: It is used when the data is non-linearly separated and hence not able to classify using a straight line.

Wikipedia explains nonlinear SVM classification with
The original maximum-margin hyperplane algorithm proposed by Vapnik in 1963 constructed a linear classifier. However, in 1992, Bernhard E. Boser, Isabelle M. Guyon and Vladimir N. Vapnik suggested a way to create nonlinear classifiers by applying the kernel trick (originally proposed by Aizerman et al.) to maximum-margin hyperplanes.
The resulting algorithm is formally similar, except that every dot product is replaced by a nonlinear kernel function. This allows the algorithm to fit the maximum-margin hyperplane in a transformed feature space.
The transformation may be nonlinear and the transformed space high-dimensional; although the classifier is a hyperplane in the transformed feature space, it may be nonlinear in the original input space.

By "linear SVM" people mean SVM with linear kernel, while every other kernel is non-linear, so SVM using it is sometimes called "non-linear" as well.

November 25, 2023 - The aim of this research is to evaluate the performance of a classification model on nonlinear data. The study utilizes accuracy, precision, sensitivity, and specificity metrics based on data from e-commerce X sellers. The classification model is developed using the Support Vector Machine (SVM) approach, employing different kernel functions such as linear, polynomial, and Radial Basis Function (RBF).

January 7, 2025 - A kernel method is a technique used in SVM to transform non-linear data into higher dimensions. For example, if the data has a complex decision boundary in a 2-Dimensional space (as Iโll explain further in the later part of this article), it can be transformed into a 3-Dimensional space.
