Figure, table and section ledger
Editorial contribution type: Training, objectives & optimization (primary).
Layout extraction, not a required paper template. Counts are distinct caption labels; a multi-panel figure counts once. Section spans are estimated from heading positions, including floats and whitespace. Method and limitations.

Section-by-section lengths and source pages
The title/abstract/front matter precede the first numbered heading. A span ends at the next detected top-level heading, not at the last sentence; end-page whitespace is included. References and statements are listed separately. These are not measurements of text-only or artwork area.

Argument and organization
- 1 Introduction; 2 Preliminaries
Motivates asymmetric visual hierarchy and introduces hyperbolic geometry before the learning rule.
- 3 Enforcing User-Defined Hierarchies; 4 Related Work
Defines containment-based pairs, bidirectional angle loss and a distribution-sensitive retrieval metric.
- 5 Experiments; 6 Conclusion
Separates same-class from hierarchical retrieval, cross-image sampling effects and out-of-domain tests.
Problem, claim and contribution
The no-hierarchical-label claim is paired with an explicit source of supervision: object boxes/classes generate containment and cross-image entailment pairs.
Sections 1 and 3.1, physical pp.1–4 · Main paper
Argument and section order
The evaluation metric is defined alongside the hierarchy construction and loss, before numerical comparisons, clarifying why ordinary recall alone is insufficient.
Sections 3.1–3.3, pp.3–5 · Main paper
Figures, captions and visual explanation
A three-panel example links nested boxes to a hierarchy and then to same-class boxes from other images, visually distinguishing two sources of positive pairs.
Figure 2, p.4 · Main paper
Tables, comparisons and evidence
Separate tables report same-class retrieval and hierarchy-distribution alignment; the precision–recall plot labels decision thresholds and uses line style to distinguish cross-image supervision.
Tables 1–2 and Figure 4, p.7 · Main paper
Appendix and reproducibility
The emergent high-frequency-crop example directs further detail to supplementary materials; this scan inspected only the static main examples and pointer.
Figure 6 and Section 5.2, p.8 · Main paper
Clarity and writing conventions
The downstream detection caption explicitly says ground-truth boxes and top-five majority voting, preventing a region-classification experiment from silently reading as end-to-end detection.

What to reuse—and what not to infer
Transferable lesson: Define the hierarchy and asymmetric retrieval target operationally, and expose privileged regions in downstream evaluation captions.
Boundary: No explicit hierarchy tree during training does not mean no annotation supervision. Box containment and class matching encode a chosen hierarchy rather than proving universal human semantic organization; geometric arguments were not proof-verified.
Apply this lesson using the argument and evidence worksheet.
