On Optimal Dimension Reduction in Least-Square System Identification - Fozunbal, Majid
Keyword(s): Dimension reduction, echo control, least-square methods, manifold learning, and regularization
Abstract: The least-square optimization problem in multi-channel echo control is severely ill-conditioned. Methods to mitigate this problem by decorrelating input signals result in undesired audio distortion. Recently, we demonstrated this approach can be tackled by dimension reduction [1]. In this paper we e ...
