DIYHealth Suite: Dataset, Model, and Benchmark for Health Management at Home
This work addresses the lack of standardized datasets, models, and benchmarks for home-based health management, enabling personalized DIY healthcare.
The paper introduces DIYHealth Suite, a framework including a large-scale multimodal dataset (DIYHealth-900K), an adaptive foundation model (DIYHealthGPT) with Hybrid Hyper Low-Rank Adaptation, and a benchmark (DIYHealthBench) for home-based health management. DIYHealthGPT achieves state-of-the-art performance on 11 home care tasks, outperforming general-purpose and medical-specific baselines.
Generative AI is reshaping healthcare, yet most existing advances rely on hospital-grade devices, which limits their accessibility and potential for health management outside clinical settings. With the proliferation of portable devices and telemedicine, healthcare is shifting toward home-based Diagnosis-It-Yourself (DIY) care. Despite this promise, several distinctive challenges remain: (i) home-collected data are heterogeneous, exacerbated by the absence of standardized large-scale datasets; (ii) models require adaptation to variable task demands and evolving individual conditions; (iii) the broad spectrum of home care tasks lacks a unified benchmark for systematic evaluation. In this paper, we present DIYHealth Suite, a comprehensive framework designed to address these challenges through a tailored dataset, model, and benchmark. We first curate DIYHealth-900K, a large-scale multimodal dataset capturing diverse real-world home care scenarios. Building on this, we propose DIYHealthGPT, an adaptive foundation model for home-based health management, powered by the novel Hybrid Hyper Low-Rank Adaptation technique. Finally, we establish DIYHealthBench, the first benchmark to evaluate foundation models on home care tasks. Extensive experiments demonstrate that DIYHealthGPT delivers state-of-the-art performance over both general-purpose and medical-specific baselines on 11 home care tasks in both open-QA and closed-QA settings, laying the groundwork for the next generation of personalized health management at home.
