To approximate solutions to problem (3) we use greedy selection with matching pursuit [Mallat and Zhang, 1993]. Assume we currently have a coreset Iˆ[N] with corresponding weights WebRETRIEVE selects the coreset by solving a mixed discrete-continuous bi-level optimization problem such that the selected coreset minimizes the labeled set loss. We use a one-step gradient approximation and show that the discrete optimization problem is approximately submodular, thereby enabling simple greedy algorithms to obtain the coreset. irish medical times jobs irish medical school acceptance rate
