    • One embodiment of the present invention provides a system that for facilitating assessment of collision between a primary principal and a non-primary principal for early warning. During operation, the system periodically performs the following operations: The system obtains a current observation of the primary principal and non-primary principal. The system then assesses one or more future states for the primary and non-primary principals, respectively, based on: the current observation of the primary and non-primary principals, a dynamics model of the primary principal, and a mental-state model of a person associated with the primary principal. The system further produces one or more results which indicate an assessment of collision between the primary and non-primary principals.
    • 本发明的一个实施例提供了一种用于便于评估主要委托人和非主要委员之间用于预警的碰撞的系统。 在运行期间,系统定期执行以下操作:系统获取主要原则和非主要委托人的当前观察结果。 然后,该制度分别基于:目前对主要和非主要负责人的观察,主要原则的动态模型和精神状态模型,评估主要和非主要原则的一个或多个未来国家 与主要委托人有关的人员。 该系统进一步产生一个或多个结果,其指示对主要和非主要负责人之间的碰撞的评估。

    • One embodiment of the present invention provides a system that facilitates assessment of collision between a primary principal and a non-primary principal for early warning. During operation, the system receives information which indicates a state of the primary principal and a state of the non-primary principal. The system divides future time into a number of time intervals, and estimates a number of possible future states of the primary and non-primary principals, wherein each future state corresponds to a time interval. The system further represents the possible future states of the primary or non-primary principal as one or more geometric objects in a space of which at least one dimension indicates the time. In addition, the system determines a probability of collision between the primary and non-primary principals based on the geometric objects.
    • 本发明的一个实施例提供了一种有助于评估初级主体和非主要委员之间的冲突用于预警的系统。 在操作期间,系统接收指示主要主体的状态和非主要委托人的状态的信息。 该系统将未来时间划分成多个时间间隔,并且估计主要和非主要负责人的可能未来状态的数量,其中每个未来状态对应于时间间隔。 该系统进一步将主要或非主要委托人的未来状态表示为至少一个维度表示时间的空间中的一个或多个几何对象。 此外,系统基于几何对象来确定主要和非主要原理之间的碰撞概率。
