## Status
Working note / experiment plan. No completed benchmark results are claimed here.
## 1. Scope and motivation
This is a working plan for studying alignment quality between image and text representations; it is not a results paper. The central question is whether the proposed change improves the target behavior under a matched training and evaluation budget. The note deliberately separates hypotheses from observations so that future results can be added without rewriting the rationale.
## 2. Context
Research on contrastive learning often mixes improvements from architecture, data scale, preprocessing, and compute. A useful comparison therefore needs controlled baselines and explicit reporting of resource use. For this topic, the main confound is that near-duplicate captions and dataset overlap can overstate generalization.
## 3. Working hypothesis
A focused change to the representation or interaction mechanism may improve Recall@1 without increasing deployment cost disproportionately. The hypothesis should be rejected if gains disappear after matching parameter count, data exposure, or tuning budget.
## 4. Proposed approach
The first implementation should keep modality-specific preprocessing simple, project inputs into a shared representation space, and isolate the new component behind a small interface. Baselines should include a comparable model without the component and a stronger off-the-shelf reference. Any optimization should be applied to all systems, not only the proposed one.
## 5. Evaluation plan
| Dataset | Role | Primary measure |
|---|---|---|
| Flickr30k | primary evaluation | Recall@1 |
| MS COCO Captions | transfer / robustness | Recall@5 |
| Winoground | transfer / robustness | median rank |
Planned comparisons include a matched-capacity baseline, an ablation that removes the proposed component, and an out-of-domain transfer check. Default training values for the first controlled run are learning rate `0.0001`, batch size `48`, and `5` independent seeds. These are planning values, not claims about a finished experiment.
## 6. Reproducibility checklist
- Publish exact split identifiers.
- Log package versions and hardware.
- Tune baselines under the same budget.
- Save both aggregate and per-category metrics.
## 7. Failure modes and responsible use
The analysis should report subgroup and category-level failures instead of relying only on a single aggregate score. Particular attention is needed because near-duplicate captions and dataset overlap can overstate generalization. No production use is recommended without task-specific validation, data review, and an assessment of privacy and bias.
## 8. Open questions
- Where does the method fail on compositional or out-of-domain examples?
- How sensitive is the conclusion to preprocessing and random seed?
- Which gain survives when the compute budget is matched?
