similar to: neural networks with RSNNS

Hola, Esta es una forma de hacerlo... Mira que lo primero que he modificado es el fichero "x.csv" para sustituir los espacios en los nombres por "_". Y también he quitado los acentos y las eñes... He utilizado el paquete RNNS y la función "mlp()" para ajustar la red. #------------------------------------------- > x <- read.csv("x.csv",

Hi I would like to know how I can change the name of a model for each trainning cycle of a model. I work with the RSNNS package and to build a neural network, I used : for (i in 5:30) .... model_ANN <- mlp(X, Y, size=n,....) # where size is the number of neurons in the hidden layer but I need to save each time that the model that is build (the end of each cycle), e.g., when i = 5, I need to

Estimados Les consulto por redes neuronales, hay diversos artículos como los siguientes (el último tienen un error actualmente). Pero mi pregunta va un poco por otro lado. http://www.r-bloggers.com/build-your-own-neural-network-classifier-in-r/ http://www.r-bloggers.com/classification-using-neural-net-in-r/ Básicamente se puede calcular un valor, por ejemplo doblar 2,4 grados a la derecha, luego 1

Hi all, I am trying to develop a neural network with single target variable and 5 input variables to predict the importance of input variables using R. I used the packages nnet and RSNNS. But unfortunately I could not interpret the out put properly and the documentation of that packages also not giving proper direction. Please help me to find a good package with a proper documentation for neural

hi all , has anyone tried to predict a univariate time series by a neural networks packages ? please help me in this problem . I am new in R and I did not found any document that explains this problem. thanks in advance David [[alternative HTML version deleted]]

Hi I am trying to plot two simple graphs with a grid in background. The axis and grid appears in correct position, but the actual data are not there.... Can somebody provide me a hint what is missing? The code is: pln <- read.table(file="PLN.txt", header=TRUE, dec=",") par(mfrow=c(1,2)) plot(pln[,1], type="l", lwd="2", ylab="EUR/PLN",

Dear R users, I am writing binding from C library to R. I use R 2.4.1, windows XP, and MinGW. commands set PKG_CPPFLAGS="-I../sources" "-I." set PKG_LIBS="-Lc:/mingw/lib" -lfl -liberty set DEBUG=T R CMD SHLIB -d --output=Rsnns.dll [ list of all C sources] produce the DLL having all defined functions in the export list. This doesn't satisfy me, as I would

Dear all May I know how to solve this problem? I have encountered this problem after I have logged out from Rstudio. Thank you Warning: namespace ?caret? is not available and has been replaced by .GlobalEnv when processing object ?fit.ann?

You haven't given much context, but these error message can come from load() when loading a *.RData file that contains objects reference packages not installed in the current installation of R. When R starts it will load a ".RData" file if one exists, this file is typically created when R shuts down and you ask it to save the current session. If you recently upgraded R you the

Previously, the R software was perfectly run without error and I am not sure why this happens. I have not installed any new R. If the *RData file is the problem, what should I do?

You are right, maintainer does keep a list of model's packages. So how do I use a variable instead of $adaboost$? getModelInfo()$adaboost$library Also, server not found: http://rwiki.sciviews.org/doku.php?id=getting-started:reference-cards:getting-help On Tue, Aug 1, 2017 at 11:46 AM, Bert Gunter <bgunter.4567 at gmail.com> wrote: > I have provided you all the

You should read the section on Indexing in the Introduction to R document that comes with R, regarding $ and `[[`. -- Sent from my phone. Please excuse my brevity.

Hello Gurus: When I plot a survival fit using rpart for the classification tree, for each node, there is a decimal based number above the event/total. I tried to see if it's the exponential ratio or logrithmics, neither seem to be the case. I'm wondering if anyone knows what they are. Thanks, Karen _________________________________________________________________ Find hidden words,

I am using the iris example came with nnet package to test AMORE. I can see the outcomes are similar to nnet with adaptative gradient descent. However, when I changed the method in the newff to the batch gradient descent, even by setting the epoch numbers very large, I still found all the iris expected class=2 being classified as class=3. In addition, all those records in the outcomes (y) are the

can u explain me, how it works your code??? please. i´m also doing a simple perceptron for homework on R and i dont know where to start. [[alternative HTML version deleted]]

Hello R masteRs, I was wondering if somebody had already implemented a parallel version of the function Nnet (with the SNOW package for instance) and would be willing to share a few pointers on how to achieve it. I have a training set of dimensions 905,000 X 5. Should I just get more RAM and run the nnet on one procesor? Or is there a slick way to parallelize the computations? I have tried to

Dear R users, I'd like to ask your guidance regarding the following two questions: (i) I just finished reading Chris Bishop's book "Neural Networks for Pattern Recognition". Although the book gave me good theoretical foundation about NN, I'm now looking for something more practical regarding architecture selection strategies. Is there any good reference about "best

Hi! I am studying to use some R libraries which are applied for working with artificial neural neworks (amore, nnet). Can you recommend some useful, reliable and easy to get example data to use in R for creating and testing a neural network? __________________________________________________________________ Make your browsing faster, safer, and easier with the new Internet

Hello everybody, I'm looking for a way to build an RBF classification network with R but I can't find any. I know there is the 'neural' package, but apparently the RBF networks I can build with that are for approximation tasks only. Is there any package I can use to build an RBF network for a classification task? I've also looked on CRAN but couldn't find any. Thank you for
