Adaptive Beamforming with a Maximum Negentropy Criterion
In this paper, we address an adaptive beamforming application in realistic acoustic conditions. After the position of a speaker is estimated by a speaker tracking system, we construct aExpand

BASED SOFT-MASK ESTIMATION FOR MISSING FEATURE RECONSTRUCTION
In this work, we show how particle filter (PF) based speech feature enhancement can profitably be combined with soft-decision missing feature reconstruction. The combined approach is motivated by theExpand

Maximum negentropy beamforming using complex generalized Gaussian distribution model
This paper presents a new beamforming method for distant speech recognition. In contrast to conventional beamforming techniques, our beamformer adjusts the active weight vectors so as to make theExpand

Localization of DNA and RNA in Eosinophil Secretory Granules
Background: Although the accepted paradigm is that the proteins stored in eosinophil crystalloid granules are translated from messenger RNA transcribed in the cell nucleus, recent ultrastructuralExpand

Erythropoietin Upregulates Brain Hemoglobin Expression and Supports Neuronal Mitochondrial Activity
Multiple sclerosis (MS) is a neuro-inflammatory and demyelinating disease. Downregulation of neuronal mitochondrial gene expression and activity have been reported in several studies of MS. We haveExpand

ON HIDDEN MARKOV MODEL MAXIMUM NEGENTROPY BEAMFORMING
In prior work, we developed a beamforming algorithm intended for automatic recognition of speech data captured with an array of distant microphones. In addition to enforcing a distortionlessExpand

DISTANT MULTI-SPEAKER VOICE ACTIVITY DETECTION USING RELATIVE ENERGY RATIO
While single-speaker voice activity detection is a well-studied problem, multi-speaker voice activity detection (MSVAD) for distant speech recognition remains a challenging task. In this work, weExpand

Filter Bank Design for Subband Adaptive Beamforming and Application to Speech Recognition
begin{abstract} We present a new filter bank design method for subband adaptive beamforming. Filter bank design for adaptive filtering poses many problems not encountered in more traditionalExpand
