Table 3: Comparison of different rollout strategies for the Full . Diverse rollouts use distinct latent variables to create more semantic diversity in rollout candidates, significantly improving performance. The size of 95% CI is within 0.19 for each entry.
['Rollout Type', 'Score vs. No Rollouts', 'Score vs. Baseline Rollouts']
Baseline Rollouts following Lewis et al. Diverse Rollouts where we first choose the top K unique zt from ^pz. By choosing unique zt we aim to increase the semantic diversity of the candidates. We evaluate compared to the baseline model and word-level rollouts and record the average score.
