The correct answer is C. 1 is true, 2 is true.
A support vector machine (SVM) is a supervised machine learning model that can be used for classification and regression tasks. SVMs work by finding a hyperplane in a high-dimensional space that separates the data into two classes. The hyperplane is chosen so that it is as far as possible from any data points, which helps to improve the model’s accuracy.
Kernel functions are used in SVMs to map the data into a higher-dimensional space. This is done because it can be easier to find a separating hyperplane in a higher-dimensional space. The kernel function is a similarity function that measures the similarity between two data points.
In conclusion, SVMs use kernel functions to map low-dimensional data to high-dimensional space. This is done to make it easier to find a separating hyperplane. The kernel function is a similarity function that measures the similarity between two data points.
