how can i enter more than one input in NARX model?
显示 更早的评论
Hi!
I want to train a NARX model, which have 1 target time series data and 3 input time series data. I tried to use the nnstool, but there I could use only 1 input data. How could I train my network with more than 1 input?
thanks, Roley

Hi Roland:
You have to arrange your 3 input series data into 1.
Please check the example "pH Neutralization Process" that comes with the system.
Run these commands and check afterwards the variable "inputSeries". This one contains two series as input.
load pH_dataset
inputSeries = phInputs;
targetSeries = phTargets;

Best regards. Fran.

What if I have a vector for each item from my input?
I have 200 cycles of data from 100 engines (with 24 parameters each).
{Engine1_Time001} {Engine2_Time001} {Engine200_Time001}
{Engine1_Time002} {Engine2_Time002} . . . {Engine200_Time002}
{Engine1_Time003} {Engine2_Time003} {Engine200_Time003}
. . .
. . .
. . .
{Engine1_Time200} {Engine2_Time200} {Engine200_Time100}
Where {EngineX_TimeY} is a 1x24 Cell containing 24 parameters of the Engine X at cycle Y.
The Neural Network Time Series App doesn't seem to be able to handle that structure since the options available are only Cell Column, Matrix Column and Matrix Row.
How can I train the NARX then?
