A new research paper explores the faithfulness of diffusion language models in table-to-text generation, comparing them against autoregressive models like GPT-2 and GPT-Neo. The study found that while diffusion models like LLaDA can achieve higher text similarity scores (BLEU), they do not necessarily improve factual grounding against the source table. Fine-tuning LLaDA with QLoRA further boosted BLEU scores but did not enhance faithfulness, indicating that reference-based metrics alone are insufficient for evaluating this aspect of generation. AI
IMPACT Highlights the limitations of current metrics for evaluating factual grounding in generative models, suggesting a need for more robust evaluation methods.
