We propose a hypergraph-based active learning scheme which we term $HS^2$, $HS^2$ generalizes the previously reported algorithm $S^2$ originally proposed for graph-based active learning with pointwise queries [Dasarathy et al., COLT 2015].

The second step is a local refinement method which leverages the underlying probabilistic model along with parameter estimation from the outcome of the first step.
