摘要: 随着机器学习模型的复杂性不断增加,对其决策过程的可解释性需求也日益增长。概念学习作为一种能够提升模型透明度和可理解性的手段,在机器学习领域变得越来越重要,通过概念来帮助解释大语言模型等黑盒模型的推理过程也随之发展,如何准确、自动地提取概念是在这一解释过程中最为关键的一环。针对现有的概念提取方法中存在的依赖人工标注、粒度不一致、扩展性差等问题,设计了一套跨模态视觉概念自动提取框架。基于多模态大模型的问询方式,实现了图像中目标对象的自动提取,并通过CLIP模型和目标检测模型实现了区域对应机制,提高了提取的准确性。采用基于文本分割的大语言模型来提取目标对象的属性和关系,确保了概念与数据的一致性。引入ConceptNet概念网络扩展了提取到的概念的语义信息,增强了框架的灵活性和适用性。通过实现这些技术,展示了该框架在三种不同场景下的实际应用效果,证明了其在提升概念提取效率和准确性以及可扩展性方面的潜力。

Abstract: As machine learning models become increasingly complex, the demand for interpretability in their decision-making processes continues to grow. Concept learning has become increasingly important in the field of machine learning as a means to enhance model transparency and comprehensibility. Consequently, the use of concepts to explain the reasoning processes of black-box models, such as large language models, has also developed. The ability to accurately and automatically extract concepts is a crucial step in this interpretability process. To address the issues in existing concept extraction methods, such as reliance on manual annotation, inconsistent granularity, and poor scalability, this paper proposes an automatic cross-modal visual concept extraction framework. This framework employs a multimodal large model-based inquiry method to achieve automatic extraction of target objects in images. The integration of the CLIP model and object detection models establishes a region-matching mechanism to enhance extraction accuracy. Additionally, a large language model based on text segmentation is utilized to extract attributes and relationships of target objects, ensuring consistency between concepts and data. Furthermore, ConceptNet is incorporated to enrich the semantic information of the extracted concepts, improving the flexibility and applicability of framework. Through the implementation of these technologies, this paper demonstrates the practical application of this framework in three different scenarios, showcasing its potential in improving the efficiency, accuracy, and scalability of concept extraction.
