Within-class covariance matrix just a note - that's the total within-class covariance matrix. |

Is whitening always good? Thanks for the clarification, you are right. I was referring to de-correlating. btw: at the end you write that whitening is only performed to the training data. as far as I know, you compute the matrix from the training data, but you perform it on both training & test data. |

Multilayer neural networks for multivariate temporal data My question was specific for multivariate temporal data, not a single channel temporal data (like those papers). thanks. |

Multilayer neural networks for multivariate temporal data I actually know this paper. They are converting their 1D temporal signal to a 2D frequency X time matrix with a spectrogram and the used 1D "filters" for the connections to the hidden units. It doesn't seem like they are looking at the frequency-time structure. Am I wrong? |

Is whitening always good? as I understand it, it works well if the covariance matrix is well-estimated. Can someone comment on this? thanks. |

Classification of observation symbols in a HMM? have you tried looking at iohmm (input-output hmm) ? might be more suitable for this case. |
