The radial basis function (RBF) is a technique used in artificial intelligence and machine learning to approximate features and solve classification and regression problems. RBF is based on a kernel function that measures the similarity between two points in a feature space.
FBR is often used in nonlinear classification problems and data interpolation. The technique is based on the concept that functions can be approximated by linear combinations of radial basis functions centered on the training data.
In FBR, the kernel function defines the relative influence of each training point on the function approximation. Training points closer to the test point have a greater influence on the approximated function.
FBR is often used in conjunction with the gradient descent algorithm to optimize kernel function parameters. It is also used in clustering problems and outlier detection.
