in case anybody will need this when googling, the ugly looking method
for boost serialization of ublas vector and matrix:
private :
friend class boost::serialization::access;
template<class Archive>
void save(Archive & ar, const unsigned int version) const
{
std::vector<std::vector<double> > l; // copy here ublas vector
std::vector<std::vector<std::vector<double> > > w; // copy here ublas matrix
l.resize(layers.size());
for(int i=0 ; i<layers.size() ; ++i)
{
l[i].resize(layers[i].size());
for(int j=0 ; j<layers[i].size() ; ++j)
l[i][j] = layers[i](j);
}
w.resize(weights.size());
for(int i=0 ; i<weights.size() ; ++i)
{
w[i].resize(weights[i].size1());
for(int j=0 ; j<weights[i].size1() ; ++j)
{
w[i][j].resize(weights[i].size2());
for(int k=0 ; k<weights[i].size2() ; ++k)
w[i][j][k] = weights[i](j,k);
}
}
ar & l;
ar & w;
}
template<class Archive>
void load(Archive & ar, const unsigned int version)
{
std::vector<std::vector<double> > l;
std::vector<std::vector<std::vector<double> > > w;
ar & l;
ar & w;
layers.resize(l.size());
for(int i=0 ; i<layers.size() ; ++i)
{
layers[i].resize(l[i].size());
for(int j=0 ; j<layers[i].size() ; ++j)
layers[i](j) = l[i][j];
}
weights.resize(w.size());
for(int i=0 ; i<weights.size() ; ++i)
{
weights[i].resize(w[i].size(),w[i][0].size());
for(int j=0 ; j<weights[i].size1() ; ++j)
for(int k=0 ; k<weights[i].size2() ; ++k)
weights[i](j,k) = w[i][j][k];
}
}
