Kernel Support Vector Machine (SVM) is a tool used for sorting things into groups based on their features. It is especially helpful when dealing with complex, non-linear patterns. In simple terms, it helps us make sense of data that doesn't follow a straight line. By using a clever trick called the kernel trick, SVM can work with data in its original form without needing to transform it into a higher-dimensional space. This trick is so useful that it is now used in many other types of computer programs that recognize patterns and learn from data.
