[ublas] serialization of ublas matrix and vector ?

hello

I'm writing a small neural network, to make things quickly I decided to
use ublas::vector and ublas::matrix to store neural layers and their
weights. The only actual operation needed for neural network to work is
simple vector matrix multiplication.

However I was surprised to discover that things are not easy when it
comes to saving/loading my neural network. Looks like boost serializtion
does not support ublas ?

Do I need to write ugly looking nested loops to serialize my data?

class NeuralNetwork
{
        public :
                typedef boost::numeric::ublas::vector<double>	Layer;  // actual values
                typedef boost::numeric::ublas::matrix<double>	Weight; // weights which connect layers
                typedef std::vector< Layer >			Layers;
                typedef std::vector< Weight >			Weights;

        private :
                Layers						layers;
                Weights						weights;

        public :
                NeuralNetwork() {};
                NeuralNetwork(boost::numeric::ublas::vector<int> layerSizes);
                void clearLayers();
                void randomizeWeights();
        
        private :
                friend class boost::serialization::access;
                template<class Archive>
                void serialize(Archive & ar, const unsigned int version)
                {
                        ar & layers;
                        ar & weights;
                }
};
