[R] a question about AMORE (newff, sim), pls help

Hi All, I try to test the neural network package AMORE, I normalized my data first, the input data is X [x1,x2,x3] where x1,x2,x3 each is 100 row 1 column vector. the output data Y is 100 row 1 column vector. my network has neurons=c(3,2,2,1) which 2 hidden layers, 3 node in the input

[R] can I use the output of a neural network as the fitness function of genetic algorithm?

Hi Everyone, I need to use genetic algorithm to find the minimum. The problem is, I cannot define the fitness function, but I can build a neural network from the input data and use the output as a fitness function. Can this be done? The other problem is, I know there are a few package

[R] incremental learning for LOESS time series model

Hi All, I am currently working on some time series data, I know I can use LOESS/ARIMA model. The data is written to a vector whose length is 1000, which is a queue, updating every 15 minutes, Thus the old data will pop out while the new data push in the vector. I can rerun the
