Kernel methods are techniques in machine learning that estimate function values at specific points. They are a generalization of support vector machines (SVM) and are widely used in various machine learning tasks such as regression, classification, and clustering.

• Support Vector Machines
• Classification algorithms
• Regression analysis
• Clustering
• Feature extraction
• Natural Language Processing (NLP)
• Image Processing
• Pattern Recognition

A kernel method could be used to estimate the height of a person based on their weight and other characteristics. By using a kernel function that maps the input features to a higher dimensional space, the model can learn non-linear relationships between the inputs and outputs, leading to more accurate predictions.
