- SensorLM: Learning the Language of Wearable Sensors2025 · arXiv preprint
SensorLM is a family of sensor-language foundation models that describe wearable data in natural language. A hierarchical captioning pipeline generates statistical, structural and semantic descriptions of the sensor data. The models show scaling behaviour, label efficiency, sensor captioning and zero-shot transfer to new tasks.
