Enhancing object recognition: The role of object knowledge decomposition and component-labeled datasets

Deep learning models' decision-making processes can be elusive, often raising concerns about their reliability. To address this, we have introduced the Object Knowledge Decomposition and Components Label Dataset (OKD-CL), designed to improve the interpretability and accuracy of object recognition models. This dataset includes 99 categories from PartImageNet, each detailed with clear physical structures that align with human visual concepts. Ina hierarchical structure, every category is described by Abstract Component Knowledge (ACK) descriptions and each image instance comes with Explicit Visual Knowledge (EVK) masks, highlighting the visual components' appearance. By evaluating multiple deep neural networks guided with ACK and EVK (dual-knowledge-guidance approach), we saw better accuracy and a higher Foreground Reasoning Ratio (FRR), confirming our knowledge-guided method's effectiveness. When used on the Hard-ImageNet dataset, this approach reduced the model's reliance on incorrect feature assumptions without sacrificing classification accuracy. This hierarchical comprehension encouraged by OKD-CL is crucial in minimizing incorrect feature associations and strengthening model robustness.
