Gaussian Processes: Why Kernels Are Priors Over Functions, Not Just Similarity Scores
Most introductions to kernels describe them as similarity measures. Two points that are close get a high kernel value, two points that are far apart get a low one, and a learning algorithm uses those similarities to interpolate. That description is not wrong, but it hides the more powerful idea beh…
