"In Dialogues We Learn": Towards Personalized Dialogue Without Pre-defined Profiles through In-Dialogue Learning
arxiv(2024)
摘要
Personalized dialogue systems have gained significant attention in recent
years for their ability to generate responses in alignment with different
personas. However, most existing approaches rely on pre-defined personal
profiles, which are not only time-consuming and labor-intensive to create but
also lack flexibility. We propose In-Dialogue Learning (IDL), a fine-tuning
framework that enhances the ability of pre-trained large language models to
leverage dialogue history to characterize persona for completing personalized
dialogue generation tasks without pre-defined profiles. Our experiments on
three datasets demonstrate that IDL brings substantial improvements, with BLEU
and ROUGE scores increasing by up to 200
the results of human evaluations further validate the efficacy of our proposed
method.
