Increasing the dimension, increasesįunction fitting is the process of training a neural network on a set of inputs in order to RBF increases the dimensionality of the feature vectors. By using such non-linear transformations, we can convert a linearly non-separable problems like inverse kinematics to a linearly separable problem. Radial basis function performs a non-linear transformation over the input vectors before input Test the accuaracy with theta_difference variables.
