saving and retrieving trained NN about neuralnetwork

[gitnichi]

I've already solved it, using the write/readCSV of the MatrixUtils class, here is the code if someone needs it, just put into the NeuralNetwork class the following methods:
/**
* Loads NN from file, with parameters supplied in myParms
* note: doesn't check matrices match sizes!
* it's up to the developer to specify them properly when invoking the NN constructor
*/

public void loadNN(String filename){
    
    mySoftmax = myParams.numClasses > 1;
    myNumOutputs = myParams.numClasses;

    // Add null params for layer 0, which is just the input and last layer, which is just output.
    myLayerParams = new NNParams.NNLayerParams[myParams.hiddenLayerParams.length+2];
    System.arraycopy(myParams.hiddenLayerParams, 0, myLayerParams, 1, myParams.hiddenLayerParams.length);
    myLayerParams[myLayerParams.length-1] = new NNParams.NNLayerParams(myNumOutputs);
    myParams.numThreads = myParams.numThreads > 0 ? myParams.numThreads : Runtime.getRuntime().availableProcessors();
    myExecutorService = Executors.newFixedThreadPool(myParams.numThreads);

    int numLayers = myLayerParams.length;
    
    initThetas();
    
    for (int layer = 1; layer < numLayers; layer++)
        try{
        myThetas[layer]=MatrixUtils.readCSV(filename+"_l"+layer+".csv",',', 0);            
        }catch(Exception e) {System.out.println(e.toString());}
}
