N2 - The growing number of observed Gamma-ray Bursts (GRBs) necessitates a more efficient use of follow-up resources in order to maximize the expected scientific returns. Studying the most distant (highest redshift) events, for instance, remain a primary goal for many in the field. Toward this goal of optimal resource allocation, we have created the Random Forests Automated Triage Estimator for GRB redshifts (RATE GRB-z) to identify high-redshift (z > 4) candidates using rapidly available metrics from the Swift satellite. Using a training set of 136 GRBs, 17 of which are high-z, our cross-validated performance metrics suggest that following up on just 20% of the GRBs will yield roughly 55% of all high-redshift events.
