Curriculum learning effectiveness hinges on reward sparsity, study finds

A new paper explores the effectiveness of curriculum learning in artificial intelligence, particularly within reinforcement learning. Researchers found that curriculum learning, which involves training on simpler versions of a task first, is significantly more beneficial in scenarios with sparse reward signals compared to dense ones. The study suggests that curricula can accelerate learning by making rewards less sparse and by shaping the reward landscape to guide agents away from suboptimal solutions, especially when faced with conflicting goals like minimizing effort and maximizing reward.
