  Resets the mean square error from the network.

  Parameters:

  ann -

• fann_get_MSE

  protected static float fann_get_MSE(com.sun.jna.Pointer ann)

  Reads the mean square error from the network.

  Parameters:

• fann_test_data

  protected static float fann_test_data(com.sun.jna.Pointer ann, com.sun.jna.Pointer data)

  Test the network using data and return the MSE of the network. You might need to run fann_reset_MSE(Pointer) first

  Parameters:

  ann -

  data - the data to test with

  Returns:

  the mean square error of the network

• fann_read_train_from_file

  protected static com.sun.jna.Pointer fann_read_train_from_file(String filename)

  Read the training or testing data from a file You must call fann_destroy_train(Pointer) on the Pointer you get from this after you have finished with it

  Parameters:

  filename - the file name of the file to read the data from

  Returns:

  pointer to the data which has been read for use with fann_test_data(Pointer,Pointer)

• fann_destroy_train

  protected static void fann_destroy_train(com.sun.jna.Pointer data)

  Deallocate the data

  Parameters:

  data - the training/testing data to deallocate
