Existing unsupervised methods struggle to fully disentangle and reconstruct composable intrinsic concepts from a single image. To address this limitation, this work introduces the CI-ICE taskβthe first framework aimed at extracting hierarchical intrinsic concepts at both object and attribute levels. We propose HyperExpress, a novel approach that integrates diffusion generative models with hyperbolic space embeddings to achieve semantic structure-preserving and relation-aware disentangled learning in a concept-level embedding space. HyperExpress substantially outperforms current state-of-the-art methods, enabling highly interpretable and strongly compositional reconstructions from individual images.
π Abstract
Unsupervised Concept Extraction aims to extract concepts from a single image; however, existing methods suffer from the inability to extract composable intrinsic concepts. To address this, this paper introduces a new task called Compositional and Interpretable Intrinsic Concept Extraction (CI-ICE). The CI-ICE task aims to leverage diffusion-based text-to-image models to extract composable object-level and attribute-level concepts from a single image, such that the original concept can be reconstructed through the combination of these concepts. To achieve this goal, we propose a method called HyperExpress, which addresses the CI-ICE task through two core aspects. Specifically, first, we propose a concept learning approach that leverages the inherent hierarchical modeling capability of hyperbolic space to achieve accurate concept disentanglement while preserving the hierarchical structure and relational dependencies among concepts; second, we introduce a concept-wise optimization method that maps the concept embedding space to maintain complex inter-concept relationships while ensuring concept composability. Our method demonstrates outstanding performance in extracting compositionally interpretable intrinsic concepts from a single image.
