Hi everybody,
first, I'm not high skilled about R, so please: be understandable!!
I would like to create an artificial neural network with R but I don't know
its parameters jet (number of layers, number of neurons,...).
I downloaded the package ANN and I use the function "ANNGA", but I'm afraid
I haven't really created a neural network. In fact, at the end of the
process I have just this output:
Call:
ANNGA.default(x = input, y = output, design = c(1, 3, 1), population = 100,
mutation = 0.2, crossover = 0.6, maxW = 10, minW = -10, maxGen = 1000,
error = 0.001)
****************************************************************************
Mean Squared Error------------------------------> 0.01148523
R2----------------------------------------------> 0.6918387
Number of generation----------------------------> 1001
Weight range at initialization------------------> [ 10 , -10 ]
Weight range resulted from the optimisation-----> [ 13.58698 , -12.93606 ]
****************************************************************************
Well, I would like to know if there is in ANN a function to *create* a
neural network and if not, which package I have to download, Nnet?
Thanks in advance!
Giulia Di Lauro.
