The paper presents a voice source waveform modeling techniques based on principal component analysis (PCA) and Gaussian mixture modeling (GMM). The voice source is obtained by inverse-filteirng speech with the estimated vocal tract filter. This decomposition is useful in speech analysis, synthesis, recognition and coding. Existing models of the voice source signal are based on function-fitting ...

Abstract Label noise is an important data quality issue that negatively impacts machine learning algorithms. For example, label has been shown to increase the number of instances required train effective predictive models. It also model complexity and decrease interpretability. In addition, can cause classification results a learner be poor. this paper, we detect with three unsupervised learner...

In this paper we propose a novel learning-based wavelet transform and demonstrate its utility as representation in solving number of linear inverse problems—these are asymmetric problems, where the forward problem is easy to solve, but difficult often ill-posed. The decomposition comprised application an invertible 2D filter-bank comprising symmetric anti-symmetric filters, combination with set...

‎in this paper‎, ‎the notion of the radical of a filter in‎ ‎residuated lattices is defined and several characterizations of‎ ‎the radical of a filter are given‎. ‎we show that if f is a‎ ‎positive implicative filter (or obstinate filter)‎, ‎then‎ ‎rad(f)=f‎. ‎we proved the extension theorem for radical of filters in residuated lattices‎. ‎also‎, ‎we study the radical‎ ‎of filters in linearly o...

in this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. in designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. the initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...

The gyroscope calibration problem is addressed for the Inertial Pseudo Star Reference Unit. A nonlinear scale factor error is described by two gyro error states (an amplitude and a decay constant) which enter the dynamics in a nonlinear fashion. A comparison is made between the extended Kalman filter (EKF) and the maximum likelihood system identification (MLSI) method for solving the resulting ...

A multi-objective optimum design method of the balanced Surface Acoustic Wave (SAW) filter is proposed. The frequency response characteristics of the balanced SAW filters are governed primarily by their geometrical structures. Besides, specifications for a balanced SAW filter is given by using several criteria. Therefore, in order to realize desirable frequency response characteristics, the str...

In this paper, a novel filter-based greedy modular subspace (GMS) technique is proposed to improve the accuracy of high-dimensional data classification. The proposed approach initially divides the whole set of high-dimensional features into several arbitrary number of highly correlated subgroups by performing a greedy correlation matrix reordering transformation for each class. These GMS can be...
