  1. ; ; ; ; ; ; ; (, 2nd Proceedings of Alexa Prize TaskBot (Alexa Prize 2023))
    We introduce MarunaBot V2, an advanced Task-Oriented Dialogue System (TODS) primarily aimed at aiding users in cooking and Do-It-Yourself tasks. We utilized large language models (LLMs) for data generation and inference, and implemented hybrid methods for intent classification, retrieval, and question answering, striking a balance between efficiency and performance. A key feature of our system is its multi-modal capabilities. We have incorporated a multi-modal enrichment technique that uses a fine-tuned CLIP model to supplement recipe instructions with pertinent images, a custom Diffusion model for image enhancement and generation, and a method for multi-modal option matching. A unique aspect of our system is its user-centric development approach, facilitated by a custom tool for tracking user interactions and swiftly integrating feedback. For a demonstration of our system, visit https://youtu.be/4MNI-puv_eE.
