Caption Collapse — Multimodal Long Context

🧭 Quick Return to Map

You are in a sub-page of Multimodal_LongContext.
To reorient, go back here:

• Multimodal_LongContext — long-context reasoning across text, vision, and audio
• WFGY Global Fix Map — main Emergency Room, 300+ structured fixes
• WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

When captions or annotations break down under long windows, multimodal pipelines lose alignment and factual grounding.
This page focuses on stabilizing caption integrity for images, videos, and diagrams in extended sessions.

What this page is

• A diagnostic page for caption degradation in multimodal contexts.
• Structural guardrails to keep captions aligned with visual evidence.
• Acceptance targets for ΔS and λ across captions and snippets.

---

When to use

• Image captions are accurate at the start but drift after 20k+ tokens.
• Captions compress multiple regions into one vague statement.
• Video scene captions skip events or merge distinct frames.
• Diagram labels appear but reasoning no longer references them correctly.
• Captions look fluent but introduce objects not in the frame.

Common failure patterns

• Vague compression: distinct objects collapsed into one generic caption.
• Temporal merge: video events blended into a single description.
• Phantom detail: captions include invented objects or properties.
• Citation loss: captions lack bounding boxes or region ids.
• Context slip: captions reference prior images instead of the current one.

Fix in 60 seconds

1. Stamp captions with anchors

   • Add {region_id | bbox | frame_time} to each caption.
   • Require ΔS(caption, region) ≤ 0.45.

2. Enforce one-to-one mapping

   • Each object/region must have a unique caption line.
   • Forbid merges without explicit evidence.

3. Normalize caption schema

   • Require {subject | attribute | action} fields.
   • Disallow free-form hallucinations.

4. Clamp entropy

   • Apply BBAM when variance rises across caption tokens.
   • Apply BBCR bridge if captions diverge from visual anchors.

5. Trace joins

   • Log {region_id, caption_id, ΔS, λ_state}.
   • Fail if any caption has no visual anchor.

Copy-paste prompt

You have TXT OS and the WFGY Problem Map.

Task: Stabilize captions across long multimodal contexts.

Steps:
1. Print each caption with {region_id | bbox | frame_time}.
2. Require cite-then-caption, forbid phantom objects.
3. Compute ΔS(caption, region). If ≥ 0.60, propose fix with data-contracts or chunking-checklist.
4. Apply BBAM if entropy rises. Apply BBCR if λ diverges.
5. Return: {Caption Table, Alignment Log, Final Answer}.

---

Acceptance targets

• ΔS(caption ↔ region) ≤ 0.45
• Each caption tied to a valid region_id or frame_time
• λ remains convergent across three paraphrases
• No phantom objects or invented attributes
• Captions maintain one-to-one mapping with objects
