Concept Discovery for Fast Adapatation
This addresses the problem of slow adaptation in meta-learning for AI researchers, offering an incremental improvement by enhancing interpretability and transferability.
The paper tackles the challenge of enabling deep learning models to quickly adapt to new tasks by introducing concept discovery into few-shot learning, achieving consistent improvements on both synthesized and real-world datasets.
The advances in deep learning have enabled machine learning methods to outperform human beings in various areas, but it remains a great challenge for a well-trained model to quickly adapt to a new task. One promising solution to realize this goal is through meta-learning, also known as learning to learn, which has achieved promising results in few-shot learning. However, current approaches are still enormously different from human beings' learning process, especially in the ability to extract structural and transferable knowledge. This drawback makes current meta-learning frameworks non-interpretable and hard to extend to more complex tasks. We tackle this problem by introducing concept discovery to the few-shot learning problem, where we achieve more effective adaptation by meta-learning the structure among the data features, leading to a composite representation of the data. Our proposed method Concept-Based Model-Agnostic Meta-Learning (COMAML) has been shown to achieve consistent improvements in the structured data for both synthesized datasets and real-world datasets.
