A radial basis function network is a type of supervised artificial neural network that uses supervised machine learning (ml) to function as a nonlinear classifier nonlinear classifiers use sophisticated functions to go further in analysis than simple linear classifiers that work on lower-dimensional vectors.
Radial basis function (rbf) networks are software systems that have certain similarities to neural networks an rbf network accepts one or more numeric input values, such as (10, -20, 30), and generates one or more numeric output values, such as (46535, 94926.

Perceptron) and rbf (radial basis function) mlp and rbf are used to catch the benefits of both in capturing non-linearity, for the prediction using mlp and rbf neural networks to improve the prediction of exchange rate time series with arima arash negahdari kia, mohammad fathian, and m r gholamian.
The radial basis function (rbf) networks are inspired by biological neural systems, in which neurons are organized hierarchically in various pathways for signal processing, and they are tuned to respond selectively to different features/characteristics of the stimuli within their respective fields. Radial basis function neural networks (rbfnns) represent an attractive alternative to other neural network models one reason is that they form a unifying link between function approximation, regularization, noisy interpolation, classification and density estimation.

Radial basis function network – a radial basis function network is an artificial neural network it uses radial basis functions as activation functions both of the above are being supervised learning networks used with 1 or more dependent variables at the output.
The radial basis function approach introduces a set of n basis functions, one for each data point, which take the form φ ( x −x p ) where φ ( ⋅ ) is some non-linear function whose form will be discussed shortly. A radial basis function network (rbfn) is a particular type of neural network in this article, i’ll be describing it’s use as a non-linear classifier generally, when people talk about neural networks or “artificial neural networks” they are referring to the multilayer perceptron (mlp. Radial basis function neural network (rbf nn) is a fami- ly of artificial neural networks that uses a nonlinear func- tion called radial basis function as an activation function.
