Teaching is a potentially effective approach for understanding interactions among multiple intelligences. Previous explorations have convincingly shown that teaching presents additional opportunities for observation and demonstration within the learning model, such as data distillation and selection. However, the underlying optimization principles and convergence of interactive teaching lack theoretical analysis, and in this regard co-teaching serves as a notable prototype. In this paper, we discuss its role as a reduction of the larger loss landscape derived from Sharpness-Aware Minimization (SAM). Then, we classify it as an iterative parameter estimation process using Expectation-Maximization. The convergence of this typical interactive teaching is achieved by continuously optimizing a variational lower bound on the log marginal likelihood. This lower bound represents the expected value of the log posterior distribution of the latent variables under a scaled, factorized variational distribution. To further enhance interactive teaching's performance, we incorporate SAM's strong generalization information into interactive teaching, referred as Sharpness Reduction Interactive Teaching (SRIT). This integration can be viewed as a novel sequential optimization process.

We introduce iTeach, a Mixed Reality (MR) framework to improve robot perception through real-time interactive teaching. By allowing human instructors to dynamically label robot RGB data, iTeach improves both the accuracy and adaptability of robot perception to new scenarios. The framework supports on-the-fly data collection and labeling, enhancing model performance, and generalization. Applied to door and handle detection for household tasks, iTeach integrates a HoloLens app with an interactive YOLO model. Furthermore, we introduce the IRVLUTD DoorHandle dataset. DH-YOLO, our efficient detection model, significantly enhances the accuracy and efficiency of door and handle detection, highlighting the potential of MR to make robotic systems more capable and adaptive in real-world environments.
