And really the leveling is designed to be a measure of how observable the inputs are to an estimate of fair value.

实际上，这种分级旨在衡量输入数据对于公允计的可观察性程度。

This work showcases a neural network that measures how the WiFi radio signals bounce around in the room and reflect off of the human body, and from these murky waves, it estimates where we are.

这一技还可以构建神经网络，用于测量 WiFi 无线电何在房间里传播并且反射出人体姿势，且从这些模糊的中可计我们的位置。
