This paper investigates methods for multimodal dialogue response retrieval, focusing on systems that can generate responses in various modalities like text and images. Researchers propose a task formulation combining three subtasks and evaluate three integration methods, including a two-step and an end-to-end approach. Experimental results indicate that the end-to-end method performs comparably without an intermediate step, and a parameter-sharing strategy enhances performance and reduces parameter count by enabling knowledge transfer across subtasks and modalities.
