A method that uses kernel functions to handle curved patterns in higher dimensions.
A kernel method is like a pop-up book for messy data. Flat blobs pop into shape, like a paper castle in math class.
It helps models handle curved patterns. You meet it in SVMs, classification, and regression, often with small data.
SVM
SVM is one of the most classic uses of kernel methods.
Classification
Kernel methods help with classes a straight line cannot split.
Regression
Kernel tricks can predict numbers, not just classes.
Deep Learning
With small data, people often compare kernel methods with Deep Learning.
