Title: Task Adaptive Meta-Learning for Computer Vision
Abstract: Few-shot learning is an emerging yet challenging problem in which the goal is to achieve generalization from only a few examples. Meta-learning tackles few-shot learning via learning prior knowledge shared across tasks and using it to learn new tasks. Owing to the flexibility and generalizability, optimization-based meta-learning algorithms have emerged as one of the promising methods for few-shot learning. MAML is one of the most popular instances of optimization approaches, owing to its simplicity and applicability across diverse problem domains. However, it is known for its low generalization performance. To overcome the limitations of the MAML-based methods, we introduce effective and flexible optimization-based meta-learning algorithms that are generalizable across diverse practical domains. More specifically, to achieve outstanding and robust performance, novel task-adaptive optimization schemes (task-adaptive initialization, task-adaptive update-rule, and task-adaptive loss function) are introduced to more effectively facilitate the adaptation to diverse tasks. The extensive experiments have demonstrated the outstanding performance of proposed meta-learning algorithms with task-adaptive optimization across few-shot learning benchmark datasets and more realistic computer vision problems such as visual tracking and video frame interpolation.
