新的REFIT方法无需标签即可校准可穿戴传感器

研究人员开发了REFIT,一种用于校准使用可穿戴传感器的活动识别模型的新颖方法。该技术解决了传感器放置偏移的问题,即像智能手表这样的设备佩戴在不同的手腕上或安装不当,导致模型因传感器轴改变而误解数据。REFIT通过识别和纠正这些偏移来实现这一点,而无需新的标签或重新训练模型。它通过拟合轴变换族(如旋转和反射)到用户数据,然后在模型处理输入之前应用最佳拟合的校正。实验表明,REFIT的性能显著优于其他无标签适应方法,并恢复了丢失的准确性。 AI

影响 该方法可以提高可穿戴传感器数据在活动识别方面的可靠性,减少在传感器重新定位时进行重新校准或重新训练的需求。

    REFIT:无需标签即可识别、修复和测试可穿戴传感器放置的偏移

    We present REFIT, an input calibration for frozen activity-recognition models whose inertial sensors are worn differently at deployment than in training. When users move a watch to the other wrist or put a strap sensor back on turned, the model sees the same motion on changed axe…
