## AI 摘要

谷歌研究院提出基础模型SensorFM，通过学习超过500万人产生的逾1万亿分钟可穿戴设备传感器数据，掌握了人类生理活动的一般性模式。该模型超越了将数据压缩为简单指标的传统方法，能够从数据中提取出有意义的结构并将其复用于多种健康预测任务。实验显示，模型规模和数据量越大性能越强，且其学习到的数据表征在35项预测任务中的34项上，均优于基于工程特征的基线方法。

New Google paper shows that wearable data becomes far more useful when AI learns the person behind the signals.

It's is not another heart-rate algorithm， but a general model trained on more than one trillion minutes of sensor data from five million people.

The authors propose SensorFM， a foundation model trained on more than 1 trillion minutes of unlabeled wearable data from 5 million people， so it can learn general patterns of human physiology before seeing specific health tasks.

That scale changes the problem from measuring isolated events to learning patterns of lived physiology： sleep， movement， temperature， oxygen， heart rhythms， and their ordinary daily messiness.

Wearables are not weak because they lack data； they are weak because most systems compress that data into crude summaries before the meaningful structure has a chance to appear.

SensorFM tries to learn that structure first， then reuse it across tasks， which is why the same representation can help with cardiovascular， metabolic， mental health， sleep， lifestyle， and demographic predictions.

The evidence is strongest as a scaling story： larger models trained on more data performed better， and the learned embeddings beat engineered-feature baselines on 34 of 35 prediction tasks.
