I am currently working with ANN for pattern recognition to identify different geological features.I am new to ANN.I am using Matlab R2011a Version 7.12.0 ANN tool box (nnstart) pattern recognition tool(nprtool).I trained ANN with input data (5x25 matrix) and target data (3x25 matrix).The algorithm itself dividing it into training,validation,test data.I followed the steps in tool box (nnstart) and finally the network was trained.Then it produced confusion plot and other.My query is how to test the data from the real world after training the network with the above input and target data?How to interpret that to which class the given input belongs from the result of ANN.Thank you all. Regards Suresh

Scroll down where it is demonstrated how to call the trained network with new inputs and how to test its performance as well.

Suresh, the targets for training are used to help the neural network understand that these are the outputs you're looking for. They are not used while testing. Testing phase is when your previously trained network is now classifying new unseen data. If you want to validate your neural net for new data, you'll need targets. This is already being done by the neural network tool. It splits the dataset into training, validation and testing. That is how it validates itself. Hope this is clear.

hei , i had the same problem , my porblem was how to use the inputs and outputs in the NN model in matlab , and i found a way , maybe i am wrong but it worth to try, because at the end i got what i want , you can use timeseries with your data , for every step , the time will be the steps and u can use from work space block as well , and that is the way i used and i go the result from the neural network !11.GIF
