predict unemployment rate using neural network
Learner IIIHi,here is my xml proces:..i wanna know if im doing this right.so many things required as i click run.i want to achieve the best neural network model of my data,performance of my model,the division set, the training and testing performance,when can i say that i already have the best model that i can alreay use for prediction,what is wrong with my data?how do i make the lables?i dont understand it clearly.and more if u can suggest..my target variable is unemployment rate, the rest are independent variables.Can anyone please help me...thank you very much

@doeyien your XML is corrupt. Please read this KB article on how to share it correctly. https://community.rapidminer.com/t5/RapidMiner-Studio-Knowledge-Base/How-can-I-share-processes-without-RapidMiner-Server/ta-p/37047
i hope this one is already ok..sorry i was ble to click 'accept as solution" earlier...
thanks again...
i'm sorry if i was able to click "accept solution" earlier,...i was trying to edit my post,..still my problems were mentioned at my post,...this is my xml process:,..i hope this one will work.
Can anyone please help me....
Okay, great. Your XML now loads, but it seems it's a bit unclear what your goal is for the data.
A couple of points, the data you provided looks a little like a time series, is that correct? Or is it to produce a prediction of the unemployment rate
Hi jEdward
thanks for paying attention on my post
Yes its a timeseries,..at the same time i have to make also predictions of unemployment rates ,..correct me if im wrong with my understading,.
Can you please suggest to me on what am i going to do with this?what about my process?am i doing the right thing?
its my first time using RM,
thanks in advance
regards,
yien
regard
heres another question,..am i going to include the variable YEAR in my data set?,..my data are from 1991-2014
@doeyien
Download the Time Series extension from the marketplace. It adds a number of sample processes using similar datasets to yours.
Have an explore of them to get a full understanding.
thanks for ur suggestion JEdward
I'll read and try the samples given
More power!
