Coarse-to-Fine Contrastive Learning in Image-Text-Graph Space for Improved Vision-Language Compositionality — Harman Singh et al. (2023) (arXiv:2305.13812, 2023)

What this evaluates

Evaluates vision-language models on compositional reasoning capabilities, specifically testing their ability to correctly bind attributes, understand semantic relations, and parse word order in image-text pairs. It also measures systematic generalization to unseen concept combinations and zero-shot classification and retrieval performance.

Datasets

• ARO — total ?; splits: test (-1)
• CREPE — total ?; splits: test (-1)
• SVO — total ?; splits: test (-1)
• VL-Checklist — total ?; splits: test (-1)

Metrics

• accuracy (primary) — range: percent
  • Standard classification accuracy: the percentage of correctly predicted labels (e.g., attribute, relation, word order, or unseen compound/atom) out of the total test instances.

Input / output format

Input: Paired image and text (sentence or phrase) instances.

Output: Predicted class label or similarity score for matching/mis-matching pairs, used to compute accuracy or Recall@1.

Scoring recipe

def compute_accuracy(predictions, gold_labels):
    correct = sum(1 for p, g in zip(predictions, gold_labels) if p == g)
    return (correct / len(gold_labels)) * 100

Common pitfalls

• Fine-tuning on COCO can cause data leakage into CREPE and ARO benchmarks due to image overlap, confounding generalization results.
• Different models use different backbones and pre-training data (OpenAI CLIP vs OpenCLIP), making direct comparison sensitive to the evaluation split and architecture.
• The 'Avg.' column in tables aggregates specific sub-metrics (Relation, Attribute, Order) rather than averaging across all datasets.

Evidence (verbatim from paper)

On average, MosaiCLIP achieves +3.3%,+6.3% better performance on the ELEVATER classification benchmark compared to NegCLIP and CLIP while pre-training and maintains similar accuracy as CLIP while fine-tuning.
