RSNNS

The Stuttgart Neural Network Simulator (SNNS) is a library containing many standard implementations of neural networks. This package wraps the SNNS functionality to make it available from within R. Using the RSNNS low-level interface, all of the algorithmic functionality and flexibility of SNNS can be accessed. Furthermore, the package contains a convenient high-level interface, so that the most common neural network topologies and learning algorithms integrate seamlessly into R.

qrnn

Fit a quantile regression neural network with optional left censoring using a variant of the finite smoothing algorithm.

monmlp

Multi-layer perceptron neural network with partial monotonicity constraints

nnet

Software for feed-forward neural networks with a single hidden layer, and for multinomial log-linear models.

neuralnet

Training of neural networks using backpropagation, resilient backpropagation with (Riedmiller, 1994) or without weight backtracking (Riedmiller and Braun, 1993) or the modified globally convergent version by Anastasiadis et al. (2005). The package allows flexible settings through custom-choice of error and activation function. Furthermore, the calculation of generalized weights (Intrator O & Intrator N, 1993) is implemented.

grnnR

grnnR synthesizes a generalized regression neural network from the supplied training data, P(atterns) and T(argets)

AMORE

This package was born to release the TAO robust neural network algorithm to the R users. It has grown and I think it can be of interest for the users wanting to implement their own training algorithms as well as for those others whose needs lye only in the "user space".
