Concept Cones: A Unifying Geometry
Our research reveals that both CBMs and SAEs, despite their different objectives, instantiate the same geometric structure: each learns a set of linear directions in activation space whose nonnegative combinations form a concept cone. This shared view allows for an 'operational bridge' where CBMs provide human-defined reference geometries, and SAEs can be evaluated by how well their learned cones approximate or contain those of CBMs. This unification moves interpretability beyond mere surface-level explanations to understanding the fundamental geometry of learned features.

Optimizing SAE Performance
Our quantitative metrics link inductive biases—such as SAE type, sparsity, or expansion ratio—to the emergence of plausible concepts. We uncover a 'sweet spot' in both sparsity and expansion factor that maximizes geometric and semantic alignment with CBM concepts. For example, intermediate sparsity regimes (~0.01-0.05%) achieve a favorable balance, maintaining reasonable geometric fidelity while attaining high coverage. This provides actionable insights for designing more interpretable AI systems.

Optimal Expansion Factor for Concept Coverage
Case Study: Husky vs. Wolf Classification
Problem: AI models often pick up on dataset biases (e.g., wolves in snow, huskies in urban settings) rather than core concepts. Our framework helps identify if SAEs learn core concepts or biases.
Approach: We applied the SAE+CBM analysis pipeline to the Husky/Wolf dataset. By mapping SAE-discovered concepts to CBM-defined concepts (e.g., 'snowy background', 'pointed ears'), we could quantify their alignment.
Outcome: The analysis revealed clear concept-frequency biases, demonstrating that the SAE+CBM pipeline successfully disentangles latent dataset biases without explicit guidance. This reinforces the interpretability benefits of combining sparse generative modeling with concept supervision to learn truly meaningful features.
