Carl C. Gaither,Alma E. Cavazos-Gaither training material is available in advance. We first present the basic NMF formulation for sound mixtures and then present criteria and algorithms for estimating the model parameters. We introduce selected methods for training the NMF source models by using either vector quantisation, convexity cons褪色 发表于 2025-3-23 15:48:28

In this chapter we will present some methods that learn to incorporate the temporal aspects of sounds and use that information to perform improved separation. We will show three such models, a conlvolutive model thaMusket 发表于 2025-3-23 18:31:04
https://doi.org/10.1007/978-0-387-49577-4ensions are introduced within a more general local Gaussian modeling (LGM) framework. These methods are very attractive since allow combining spatial and spectral cues in a joint and principal way, but also are natural extensions and generalizations of many single-channel NMF-based methods to the muhandle 发表于 2025-3-24 00:42:17

Carl C. Gaither,Alma E. Cavazos-Gaithers (IVA) and nonnegative matrix factorization (NMF). IVA is a state-of-the-art technique that utilizes the statistical independence between source vectors. However, since the source model in IVA is based on a spherically symmetric multivariate distribution, IVA cannot utilize the characteristics of sIngenuity 发表于 2025-3-24 07:02:44

Carl C. Gaither,Alma E. Cavazos-Gaither More computationally demanding approaches tend to produce better results, but often not fast enough to be deployed in practical systems. For example, as opposed to the iterative separation algorithms using source-specific dictionaries, a Deep Neural Network (DNN) performs separation via an iteratioUrgency 发表于 2025-3-24 16:34:20
