LaVy: A Pioneering Vietnamese Multimodal Large Language Model for Advancing Visual-Linguistic Understanding

Core Concepts

LaVy is a state-of-the-art Vietnamese Multimodal Large Language Model (MLLM) that aims to bridge the gap between Vietnamese Large Language Models (LLMs) and MLLMs, enabling complex reasoning and linguistic comprehension in tasks that involve both visual and textual information.

Abstract

The paper introduces LaVy, the first Vietnamese Multimodal Large Language Model (MLLM), and the LaVy-Bench benchmark designed to evaluate the performance of Vietnamese MLLMs.
Key highlights:

LaVy is built using the LlaVA architecture, integrating a vision encoder, an MLP projector, and a large language model.
The authors curated a high-quality Vietnamese dataset of 708K image-caption pairs and 166K instructions for pretraining and finetuning LaVy.
LaVy outperforms multilingual baselines like mBLIP on zero-shot Vietnamese Visual Question Answering (VQA) and an in-the-wild benchmark, demonstrating its strong multimodal understanding.
The LaVy-Bench benchmark is introduced to facilitate the evaluation and comparison of Vietnamese MLLMs, consisting of a zero-shot VQA task and an in-the-wild test set.
While LaVy exhibits impressive performance, the authors acknowledge limitations such as challenges in handling tasks like OCR and object counting due to lack of annotated data, as well as the model's susceptibility to hallucination.
The paper concludes by highlighting the significance of LaVy and the LaVy-Bench benchmark in advancing Vietnamese MLLM research and fostering the development of more capable multimodal language models for the Vietnamese language.
