Maximum Negentropy Beamforming
In this paper, we address an adaptive beamforming application based on the capture of far-field speech data from a single speaker in a real meeting room. After the position of a speaker is estimated by a speaker tracking system, we construct a subband-domain beamformer in generalized sidelobe canceller (GSC) configuration. In contrast to conventional practice, we then optimize the active weight...
متن کاملOn 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 distortionless contraint in a desired direction, we adjusted the sensor weights so as to maximimize a negentropy criterion. Negentropy is a measure of how non-Gaussian the probability density function (pdf) of a random va...
متن کاملFuzzy Cluster Validation Using the Partition Negentropy Criterion
We introduce the Partition Negentropy Criterion (PNC) for cluster validation. It is a cluster validity index that rewards the average normality of the clusters, measured by means of the negentropy, and penalizes the overlap, measured by the partition entropy. The PNC is aimed at finding well separated clusters whose shape is approximately Gaussian. We use the new index to validate fuzzy partiti...
متن کاملA Spatio-Temporal Equalization Method with Beamforming Criterion Selectability
This paper proposes a spatio-temporal equalization method, which employs a cascade configuration of an adaptive array and a decision feedback equalizer (DFE). With the configuration, the proposed equalizer requires small number of weights, and hence, low computational complexity, however, it has to pay a price for the simplicity, namely, noise enhancement due to high sidelobe levels in certain ...
متن کاملModelling the nonstationarity of speech in the maximum negentropy beamformer
State-of-the-art automatic speech recognition (ASR) systems can achieve very low word error rates (WERs) of below 5% on data recorded with headsets. However, in many situations such as ASR at meetings or in the car, far field microphones on the table, walls or devices such as laptops are preferable to microphones that have to be worn close to the user’s mouths. Unfortunately, the distance betwe...
