• Abstract: Many studies have found active learning, either in the form of in-class exercises or projects, to be superior to traditional lectures. However, these forms of hands-on learning do not always lead students to reach the higher order thinking skills associated with the highest levels of Bloom's Taxonomy (analysis, synthesis, and evaluation). Assignments that expect students to follow a prescribed approach to reach a well-defined solution contribute to a lack of higher order thinking at the college level. Professional engineers often face complex and ambiguous problems that require design decisions for which there is no straightforward answer. To strengthen the higher order thinking skills demanded by such problems, we developed a project in a semester-long mechatronics course in which students must evaluate two automatic control methodologies without being given explicit performance criteria or experimental procedures. Specifically, the project involves determining the superior control method for leader-follower behavior, where a ground vehicle autonomously follows a lead vehicle. Laboratory exercises throughout the semester expose students to the skills required for the project, including using sensors and actuators, programming proportional-integral-derivative (PID) and fuzzy controllers, and applying computer vision to detect an object signature. In the final course project, students go beyond implementing individual controllers and create their own evaluation criteria and experiments to make a design decision between PID and fuzzy control. We implemented this approach over three semesters and found that students value working on a real-world, open-ended problem, develop creative performance criteria and evaluation methods that demonstrate higher order thinking, and discover that comparative studies are nontrivial due to the many factors influencing performance.

  Intrinsic motivations have proven to generate a task-agnostic signal to properly allocate the training time amongst goals. While the majority of works in the field of intrinsically motivated open-ended learning focus on scenarios where goals are independent from each other, only few of them studied the autonomous acquisition of interdependent tasks. In particular, we first deepen the analysis of a previous system, showing the importance of incorporating information about the relationships between tasks at a higher level of the architecture. Then we introduce H-GRAIL, a new system that extends the previous one by adding a new learning layer to store the autonomously acquired sequences

  Policy distillation, which transfers a teacher policy to a student policy, has achieved great success in challenging tasks of deep reinforcement learning. In this work, we introduce dual policy distillation(DPD), a student-student framework in which two learners operate on the same environment to explore different perspectives of the environment. The key challenge in developing this dual learning framework is to identify the beneficial knowledge from the peer learner for contemporary learning-based reinforcement learning algorithms.
