摘要:

大语言模型(LLMs)已在多个领域展现出卓越能力。然而,将LLMs用于普适感知应用仍具挑战性,因为现有文本提示方法在处理长传感器数据序列时性能显著下降。我们提出一种面向传感器数据的视觉提示方法,使用多模态大语言模型(MLLMs)。我们设计了一种视觉提示,引导MLLMs同时利用可视化传感器数据和目标感知任务描述。此外,我们引入了一个可视化生成器,能够针对给定感知任务自动生成最优可视化,无需事先具备任务特定知识。我们在涉及四种感知模态的九个感知任务上评估了该方法,相比基于文本的提示平均准确率提高10%,并将token成本降低15.8倍。我们的研究结果表明,视觉提示与MLLMs结合在各种感知任务中具有有效性和成本效率。源代码可在 https://github.com/diamond264/ByMyEyes 获取。

英文摘要:

Large language models (LLMs) have demonstrated exceptional abilities across various domains. However, utilizing LLMs for ubiquitous sensing applications remains challenging as existing text-prompt methods show significant performance degradation when handling long sensor data sequences. We propose a visual prompting approach for sensor data using multimodal LLMs (MLLMs). We design a visual prompt that directs MLLMs to utilize visualized sensor data alongside the target sensory task descriptions. Additionally, we introduce a visualization generator that automates the creation of optimal visualizations tailored to a given sensory task, eliminating the need for prior task-specific knowledge. We evaluated our approach on nine sensory tasks involving four sensing modalities, achieving an average of 10% higher accuracy than text-based prompts and reducing token costs by 15.8 times. Our findings highlight the effectiveness and cost-efficiency of visual prompts with MLLMs for various sensory tasks. The source code is available at https://github.com/diamond264/ByMyEyes.
