Summary
Despite rapid development of machine learning techniques that can generalize beyond the distribution of the training data, these models are still far behind the learning pace of young children. In this proposal, we leverage insights from developmental psychology regarding children's learning environment and strategies to apply to machine algorithms. To achieve this goal, we focus on two aspects of children's word and object learning: 3D information and mutual exclusivity bias. We conduct studies on the generalization ability of 3D reconstruction models, identifying key factors that affect this capability. Extending our exploration, we demonstrate that 2D feature representations with strong semantic correspondence matching ability can be effectively employed for 3D object part segmentation. Additionally, we introduce a novel paradigm for low-shot learning, requiring computational models to leverage mutual exclusivity bias to resolve ambiguity in learning signals. Our main goal is to develop a part-based self-supervised learning model that aggregates 3D information from multiple viewpoints. We plan to show that this approach can be applied to address the challenges of low-shot object learning with mutual exclusivity bias setting.
