📝 摘要(中文)

大型语言模型(LLMs),如ChatGPT/GPT-4,已被证明是提升用户体验的强大工具。然而,针对特定领域的多模态大型语言模型(MLLM)仍然较少,尤其是在海洋领域。现有的LLMs和MLLMs在理解领域特定意图和生成信息丰富的响应方面能力有限。为此,本文提出了MarineGPT,这是首个专为海洋领域设计的视觉-语言模型,旨在向公众揭示海洋的秘密。我们还构建了Marine-5M数据集,包含超过500万对海洋图像-文本对,以增强模型的海洋知识和视觉语言对齐能力。MarineGPT不仅推动了海洋理解的边界,还为将通用助手适应于领域专家提供了标准协议。

🔬 方法详解

问题定义:本文旨在解决现有多模态大型语言模型在海洋领域特定知识理解和响应生成方面的不足,现有模型在处理领域特定意图时表现不佳。

核心思路:提出MarineGPT,专门针对海洋领域的视觉-语言模型,通过构建Marine-5M数据集来注入领域特定知识,从而提高模型的响应质量和信息准确性。

技术框架:MarineGPT的整体架构包括数据收集、模型训练和评估三个主要阶段。数据收集阶段通过构建Marine-5M数据集,模型训练阶段采用多模态学习策略,评估阶段则通过与现有模型的对比来验证效果。

关键创新:MarineGPT的最大创新在于其专为海洋领域设计的多模态学习框架,区别于通用模型,能够生成更为敏感和科学的海洋相关响应。

关键设计:在模型设计中,采用了特定的损失函数以优化视觉和语言的对齐,同时在网络结构上进行了调整,以适应海洋领域的特定需求。

🎯 应用场景

MarineGPT的潜在应用场景包括海洋科学教育、海洋资源管理、环境保护等领域。通过提供准确的海洋知识和信息,MarineGPT能够帮助公众更好地理解海洋生态系统,促进科学传播和公众参与。同时,该模型的标准协议也为将来其他领域的应用提供了借鉴。

📄 摘要(原文)

Large language models (LLMs), such as ChatGPT/GPT-4, have proven to be powerful tools in promoting the user experience as an AI assistant. The continuous works are proposing multi-modal large language models (MLLM), empowering LLMs with the ability to sense multiple modality inputs through constructing a joint semantic space (e.g. visual-text space). Though significant success was achieved in LLMs and MLLMs, exploring LLMs and MLLMs in domain-specific applications that required domain-specific knowledge and expertise has been less conducted, especially for \textbf{marine domain}. Different from general-purpose MLLMs, the marine-specific MLLM is required to yield much more \textbf{sensitive}, \textbf{informative}, and \textbf{scientific} responses. In this work, we demonstrate that the existing MLLMs optimized on huge amounts of readily available general-purpose training data show a minimal ability to understand domain-specific intents and then generate informative and satisfactory responses. To address these issues, we propose \textbf{MarineGPT}, the first vision-language model specially designed for the marine domain, unlocking the secrets of the ocean to the public. We present our \textbf{Marine-5M} dataset with more than 5 million marine image-text pairs to inject domain-specific marine knowledge into our model and achieve better marine vision and language alignment. Our MarineGPT not only pushes the boundaries of marine understanding to the general public but also offers a standard protocol for adapting a general-purpose assistant to downstream domain-specific experts. We pave the way for a wide range of marine applications while setting valuable data and pre-trained models for future research in both academic and industrial communities.
