Picturing Ambiguity: A Visual Twist on the Winograd Schema Challenge

Problem and motivation

Text-to-image models can generate visually plausible images without resolving which entity an ambiguous pronoun refers to. Existing WSC-style reasoning evaluations are mainly textual and do not isolate multimodal pronoun disambiguation from image-generation artifacts.

Method and contribution

WINOVIS contains 500 WSC-adapted scenarios generated through GPT-4 prompting and manually filtered for textual ambiguity, illogical content, visual indistinctiveness, and redundancy. The evaluation uses Stable Diffusion generations, DAAM cross-attention heatmaps, caption filtering, 90th-percentile heatmap thresholding, and IoU-based overlap/decision rules. A single pronoun-to-entity association is accepted when the pronoun heatmap crosses IoU 0.4 with one or the stronger of the two referents.

Findings and evidence

The paper evaluates Stable Diffusion versions labeled 1.0/1.5/2.0 and XL in Tables 2-3; the setup prose says 1.1/1.5/2.0/XL. SD 2.0 reports 56.7% precision, 24.2% recall, 34.1% F1, and 36.1% certainty, with 55 correct, 42 incorrect, and 172 neither outcomes in the table. SDXL produces mostly unusable heatmap decisions. Error analysis shows much weaker handling of visually distinct entities than disparate entities.

Limitations and future directions

Limitations: Entity separation, semantic entanglement, captioned images, DAAM availability only for open Stable Diffusion models, bias, and limited scenario diversity affect validity. The metrics assess heatmap/association behavior rather than human-level or task-functional multimodal reasoning. GPU/CPU, OS, runtime, and replication details are unknown.

Future work: Improve entity separation and entanglement filtering, study bias, expand context and entity diversity, and develop interpretability methods for more diffusion models.
