It would be kind of convolved to try to cast an ublas vector to a vector expression. Will the following achieve what you want?

#include <boost/numeric/ublas/vector.hpp>
#include <boost/numeric/ublas/io.hpp>
#include <unordered_map>
#include <string>
#include <iostream>


int main()
{
    std::unordered_map<std::string, boost::numeric::ublas::vector<int> > c;

    boost::numeric::ublas::vector<int> v (10);
    for (unsigned i = 0; i < v.size (); ++ i)
        v (i) = i;
   
    c["first"] = v;

    std::cout << c["first"] << std::endl;
    return 0;
}
