" Once we scale up, algorithms must be sensitive to tiny changes in identities and at the same time invariant to lighting, pose, age, " Kemelmacher-Shlizerman said.
Kemelmacher-Shlizerman 说：“一旦我们扩大数据库规模，算法必须对身份的微小变化敏感，同时不随光照、姿势、年龄变化。”

时不变系统 Time-invariant system
（重定向自Time invariant）
非时变系统是输出不会直接随着时间变化的系统。
- 如果输入信号
产生输出
，那幺对于任意时间延迟的输入
将得到相同时间延迟的输出
。
如果系统的传递函数不是时间的函数，就可以满足这个特性。这个特性也可以用示意图的术语进行描述
- 如果一个系统是时不变的，那幺系统框图与任意延时时刻的框图都是可以互换的。

（重定向自Time invariant）
A time-invariant (TIV) system is a system whose output does not depend explicitly on time. Such systems are regarded as a class of systems in the field of system analysis. Lack of time dependence is captured in the following mathematical property of such a system:
