Independent dynamics subspace analysis
Alexander Ilin · 2006
Abstract. The paper presents an algorithm for identifying the indepen-dent subspace analysis model based on source dynamics. We propose to separate subspaces by decoupling their dynamic models. Each subspace is extracted by minimizing the prediction error given by a first-order non-linear autoregressive model. The learning rules are derived from a cost function and implemented in the framework of denoising source separa-tion. 1
