Karhunen-Loève(KL)分解被广泛用于通常表现出一些对称性的数据,这些对称性由群作用提供。对于有限群,我们利用群表示理论导出了一个算法,以减少确定KL基的成本。我们证明了一个Lorenz型常微分方程系统的技术。对于一个紧群,如环面或SO(3,R)的方法也适用,我们将结果扩展到这些情况。作为一个简单的例子,我们考虑圆群S(1)。
The Karhunen-Loève (KL) decomposition is widely used for data which very often exhibit some symmetry, afforded by a group action. For a finite group, we derive an algorithm using group representation theory to reduce the cost of determining the KL basis. We demonstrate the technique on a Lorenz-type ODE system. For a compact group such as tori or SO(3,R) the method also applies, and we extend results to these cases. As a short example, we consider the circle group S(1).
