We identify a form of RBF classifier whose expected outputs can easily be evaluated in terms of the original function parameters. We then describe two ways in which this classifier can be applied to robust automatic speech recognition, depending on whether or not the position of missing data is knownspeechneural networksrobust recognitionmissing featuresA neural network for classification with incomplete data: application to robust ASRtext::conference output::conference proceedings::conference paper
