Medium	GrooveSquid.com (original content)	Medium Difficulty Summary A novel reinforcement learning algorithm, EARLY, is introduced to optimize the selection of human demonstrations for improving sample efficiency. By utilizing a trajectory-based feature space, EARLY determines the most beneficial queries for expert demonstrations based on an estimate of uncertainty in the agent’s policy. This approach enhances the human teaching experience and achieves better learning performance compared to baseline methods. The algorithm is validated through three simulated navigation tasks, demonstrating faster convergence (30%) and improved performance. A pilot user study with 18 participants further confirms the effectiveness of EARLY, achieving a better user experience while consuming less human time.
Low	GrooveSquid.com (original content)	Low Difficulty Summary A new way to learn from experts is being developed. This method, called EARLY, helps choose the best examples for a computer to learn from. Instead of just showing the computer individual actions, EARLY shows it sequences of actions. This makes learning more efficient and effective. The algorithm was tested in three simulation tasks and worked better than other methods. It also made the process easier and faster for people teaching computers.
