    • Components, methods, and apparatuses are provided that may be used to determining activity likelihood function values for the activity classification for two or more past epochs based, at least in part, on signals from one or more sensors of a mobile device. For example, a method may comprise, for each of a plurality of activity classifications, determining activity likelihood function values for each of the plurality of activity classifications for two or more past epochs. The activity likelihood function values are based, at least in part, on signals from one or more sensors of a mobile device. The method may also include combining the activity likelihood function values to determine a likelihood function for an activity classification at a present epoch. The method may also include inferring a present activity of a user co-located with the mobile device to be one of the activity classifications based, at least in part, on the determined likelihood functions for the activity classifications at the present epoch.
    • 提供了组件,方法和装置,其可以用于至少部分地基于来自移动设备的一个或多个传感器的信号来确定两个或多个过去时期的活动分类的活动似然函数值。 例如,对于多个活动分类中的每一个,方法可以包括为两个或更多个过去时期的多个活动分类中的每一个确定活动似然函数值。 活动似然函数值至少部分地基于来自移动设备的一个或多个传感器的信号。 该方法还可以包括组合活动似然函数值以确定在当前时期的活动分类的似然函数。 该方法还可以包括将至少部分地基于所确定的在当前时期的活动分类的可能性函数推测出与移动设备共存的用户的当前活动为活动分类之一。
