I am trying to make an NN for meteorological prediction, for which I have input data of only one meteorological station. I have target data of more than one location.
I have to train the NN in such a way that I gove it two input values (e.g.current temperature, pressure) and want to obtain temperature output at more than 50 locations and more than one time steps.
e.g. the input :
(25, 101.32)
should give output:
temperature after 2 hrs = 25, 26, 28, 29, 27.5
temperature after 4 hrs = 24, 23, 26, 26.5, 27
In which pattern to arrange the input and target data, and how to change the number of NN output nodes to obtain these results?
here the mapping is from a lower dimension to a higher dimension, you can do that using a variant of the Auto encoder neural networks. the input can be fixed at and out put at 5. then dropout regularization can be implemented for preventing overfitting.
Dear Naqash Manzoor
Once you get your desire ANN model, you have to generate a function by clicking 'MATLAB Function' (Fig. 2).
Then you have to save the function (default name is 'myNeuralNetworkFunction').
(keep file name and function same) (Fig. 4)
Again, you have to create a custom function using 'myNeuralNetworkFunction'
For instance, the function name 'funct' (Fig. 5) (keep file name and function name same).
Now, your objective function is 'funct'. Here, a negative sign is given because the present study is for maximization. (GA toolbox only do minimization, therefore the function has been modified with negative sign). For minimization problem, please keep it positive.
Again, this function can be used for response prediction.
Do not worry, there will be a negative value of an optimum objective function after GA optimization. However, you have to take the mod value of the function.
Recently I have published one article on the application of ANN, SVM, GA and PSO in a biological system (using MATLAB). This paper might help you.
