• Title: Multilingual Conceptual Coverage in Text-to-Image Models
• Authors: Michael Saxon, William Yang Wang
• Abstract summary: "Conceptual Coverage Across Languages" (CoCo-CroLa) is a technique for benchmarking the degree to which any generative text-to-image system provides multilingual parity to its training language in terms of tangible nouns. For each model we can assess "conceptual coverage" of a given target language relative to a source language by comparing the population of images generated for a series of tangible nouns in the source language to the population of images generated for each noun under translation in the target language.

• Abstract: We propose "Conceptual Coverage Across Languages" (CoCo-CroLa), a technique for benchmarking the degree to which any generative text-to-image system provides multilingual parity to its training language in terms of tangible nouns. For each model we can assess "conceptual coverage" of a given target language relative to a source language by comparing the population of images generated for a series of tangible nouns in the source language to the population of images generated for each noun under translation in the target language. This technique allows us to estimate how well-suited a model is to a target language as well as identify model-specific weaknesses, spurious correlations, and biases without a-priori assumptions. We demonstrate how it can be used to benchmark T2I models in terms of multilinguality, and how despite its simplicity it is a good proxy for impressive generalization.

  We introduce Babel-ImageNet, a massively multilingual benchmark that offers partial translations of ImageNet labels to 100 languages. We evaluate 11 public multilingual CLIP models on our benchmark, demonstrating a significant gap between English ImageNet performance and that of high-resource languages. We show that the performance of multilingual CLIP can be drastically improved for low-resource languages with parameter-efficient language-specific training.

We create a multilingual dataset for Multicultural Reasoning over Vision and Language (MaRVL) by eliciting statements from native speaker annotators about pairs of images.
