TLPIQ at BioLaySumm: Hide and Seq, a FLAN-T5 Model for Biomedical Summarization

BioLaySumm 2025 is a shared task that aims to automatically generate lay summaries of scientific papers for a wider audience of readers without domain-specific knowledge, making scientific discoveries in the domain of biology and medicine more accessible to the general public.Our submission to the task is a FLAN-T5 base model fine-tuned on the abstract and conclusion of articles and expert-written lay summaries from the shared task's provided datasets.We find that our system performs competitively in terms of relevance, exceeds the baseline on factuality, but falls short on readability.
