The paper investigates the capabilities of contrastive vision-and-language models (VLMs) in understanding image-based advertisements. It’s found that these models can solve an ad-explanation retrieval task by exploiting grounding heuristics, which are biases that humans tend to use when interpreting multimodal stimuli. To control for this confound, the authors introduce TRADE, a new evaluation test set with adversarial grounded explanations that “fool” four different contrastive VLMs. The study highlights the need for an improved operationalisation of automatic ad understanding that truly evaluates VLMs’ multimodal reasoning abilities.
Low GrooveSquid.com (original content) Low Difficulty Summary
Automatic ads are complex and often use unusual visual elements and figurative language. Researchers have used special computer models to understand these ads, and they’ve had great success on a task called ad-explanation retrieval. However, this study shows that the models can solve the task by using biases we humans tend to apply when interpreting multimodal stimuli. To test how well the models really work, the authors created a new set of explanations for ads that are designed to trick the models. The results show that four different models were fooled by these fake explanations.
