摘要:
当前的视觉语言模型(VLM)在视觉问答等多样任务中展现出卓越的能力。为了提升用户体验,近期研究探索了VLM的个性化,以理解用户提供的概念。然而,这些研究主要聚焦于单概念个性化,忽视了多概念的存在及其相互作用,这限制了其在现实世界中的适用性。本文提出了首个多概念个性化范式MC-LLaVA。具体而言,MC-LLaVA采用多概念指令微调策略,在单次训练步骤中有效整合多个概念。为降低联合训练的相关成本,我们提出了一种个性化文本提示,利用视觉令牌信息初始化概念令牌。此外,我们在推理阶段引入个性化视觉提示,聚合位置置信度图以增强识别和定位能力。为推动多概念个性化研究,我们进一步贡献了一个高质量的指令微调数据集。我们精心收集了电影中包含多个人物和物体的图像,并手动生成面向多概念场景的问答样本,具有卓越的多样性。全面的定性和定量实验表明,MC-LLaVA能够实现令人印象深刻的多概念个性化响应,为VLM成为更好的用户特定助手铺平了道路。代码和数据集将在https://github.com/arctanxarc/MC-LLaVA公开提供。
英文摘要:
Current vision-language models (VLMs) show exceptional abilities across diverse tasks, such as visual question answering. To enhance user experience, recent studies investigate VLM personalization to understand user-provided concepts. However, they mainly focus on single-concept personalization, neglecting the existence and interplay of multiple concepts, which limits real-world applicability. This paper proposes the first multi-concept personalization paradigm, MC-LLaVA. Specifically, MC-LLaVA employs a multi-concept instruction tuning strategy, effectively integrating multiple concepts in a single training step. To reduce the costs related to joint training, we propose a personalized textual prompt that uses visual token information to initialize concept tokens. Additionally, we introduce a personalized visual prompt during inference, aggregating location confidence maps for enhanced recognition and grounding capabilities. To advance multi-concept personalization research, we further contribute a high-quality instruction tuning dataset. We carefully collect images with multiple characters and objects from movies and manually generate question-answer samples for multi-concept scenarios, featuring superior diversity. Comprehensive qualitative and quantitative experiments demonstrate that MC-LLaVA can achieve impressive multi-concept personalized responses, paving the way for VLMs to become better user-specific assistants. The code and dataset will be publicly available at https://github.com/arctanxarc/MC-LLaVA}.
