We consider a complete set of dimension-six operators affecting $W^-W^+\\gamma/Z$ vertex, which are $SU(2)\\times U(1)$ gauge invariant. Some of the polarization and spin correlation asymmetries average out if the daughter of $W^+$ is not tagged. We developed an artificial neural network and boosted decision trees to distinguish down-type jets from up-type jets.
