Title: Towards Efficient Parallel Learning



Online learning approaches are often the most efficient methods for learning on a dataset.  For really big datasets however, they are not efficient enough, simply because the bandwidth requirements are too great.  How can we effectively apply and adapt our efficient online learning algorithms to parallel environments?  I will describe what we've learned so far for both multicore and multinode parallelization.
