Speaker verification is the process of determining the validity of a claimed identity through voice. Traditional approaches to this problem are Gaussian mixture models and hidden Markov models. Although these methods work well, they are difficult to employ in an adaptive framework because of the iterative nature of training. Ideally, as we acquire new-labeled input, we would like to update the ...

Fig. 12. Comparison between the number of functional evaluations with gaussian and exponential damping functions. The results on a complete sweep on 24 values of m in 0,1] are shown. Finally, we should note that the choice of gaussian damping for the memory mechanism is not critical. We experimented with a pure exponential damping getting similar results. This suggests that the dynamic mechanis...

abstract   aim and background: the forgetfulness or memory deficit hypothesis in patients with obsessive–compulsive disorder (ocd) has been used to explain the maintenance of repetitive behaviors in these patients. yet the majority of studies focusing on memory of patients with ocd show mixed results. the aim of this study was to compare of false memory and memory confidence in women with obses...

An adaptive numerical method for solution of the time-dependent Schrödinger equation is presented. By using an interpolating wavelet transform the number of used points can be reduced, constructing an adaptive sparse point representation. Two di erent discretisation approaches are studied in 1D ; one point-based and one based on equidistant blocks. Due to the nature of the wavelet transform a s...

Abstract Aiming at the problem that nonlinearity of tracking state equation and strong noise in measurement process target, a non-cooperative target method geostationary earth orbit based on adaptive memory attenuation UKF is proposed. Firstly, relative motion model constructed, are established. Use adjustment factor to enhance correction effect new estimation, improve adaptability filtering no...

In dealing with model predictive controllers (MPC), controller tuning is a key design step. Various tuning methods are proposed in the literature which can be categorized as heuristic, numerical and analytical methods. Among the available tuning methods, analytical approaches are more interesting and useful. This paper is based on a proposed analytical MPC tuning approach for plants can be appr...

Among the adaptive-grid methods, redistribution and embedding techniques have been the focus of more attention by researchers. Simultaneous or combined adaptive techniques have also been used. This paper describes a combination of adaptive-grid embedding and redistribution methods on semi-structured grids for two-dimensional invisid flows. Since the grid is semi-structured, it is possible to us...
