Re^4: AI Neural Networks based Prediciton

Hi,
Thanks.
For example, NASDAQ Index "XYZ", the following values are the daily rate .

"2010-02-03" = 23.25;
"2010-02-04" = 32.02;
"2010-02-05" = 28.21;
"2010-02-06" = 12.25;

Can you suggest me what output I can define for the above input data .
how do I predict the value for "2010-02-07" ?
Please correct me if I am missing anything

The common approach is to train your network on the data you have, and then use the last data item as the goal. In your example, you would train your network on the days for 2010203, 2010204, 2010205, and then test it (for example) against 2010206. Soon after, you will encounter the miracle of Overfitting your model to your training data. Also, you will find that if (say) neural networks were good at predicting "the market", everybody would already be using them.	[reply]

Hi, Thanks. Can you suggest me with example what would be a input and output for stock data ? Once I get it correctly, then I will add training sets in multiple source to overcome "Overfitting". Please bring me up from basic. Thanks, Raja K	[reply]

You already have input and output for stock data in Re^4: AI Neural Networks based Prediciton. The trick is to use half (or 90% ) of your data as input data and the rest as output data.	[reply]
