You have a much better chance of being allowed to go if you have some work to present. If you have just started then obviously that's going to be a bit difficult! If you do have some suitable work, how about drafting an abstract (you'll find the details on the conference home page) and then showing your supervisor? If not, no harm in asking anyway, the worst they can say is no (in which case aim for next year's conference when you'll have something to present!). Good luck!
