An Investigation on Mutual Information for the Linear Predictive System and the Extrapolation of Speech Signals

Speech Communication; 10. ITG Symposium, 2012

Mutual information (MI) is an important information theoretic concept which has many applications in telecommunications, in blind source separation, and in machine learning. More recently, it has been also employed for the instrumental assessment of speech intelligibility where traditionally correlation based measures are used. In this paper, we address the difference between MI and correlation from the viewpoint of discovering ...

  • An Investigation on Mutual Information for the Linear Predictive System and the Extrapolation of Speech Signals

    Mutual information (MI) is an important information theoretic concept which has many applications in telecommunications, in blind source separation, and in machine learning. More recently, it has been also employed for the instrumental assessment of speech intelligibility where traditionally correlation based measures are used. In this paper, we address the difference between MI and correlation from the viewpoint of discovering dependencies between variables in the context of speech signals. We perform our investigation by considering the linear predictive approximation and the extrapolation of speech signals as examples. We compare a parametric MI estimation approach based on a Gaussian mixture model (GMM) with the knearest neighbor (KNN) approach which is a well-known non-parametric method available to estimate the MI. We show that the GMM-based MI estimator leads to more consistent results.

  • Estimation of solar energetic proton mission-integrated fluences and peak intensities for missions traveling close to the Sun

    A method to estimate both solar energetic particle mission-integrated fluences and solar energetic particle peak intensities for missions traveling through the innermost part of the heliosphere (r < 1 AU) is presented. By using (1) an extensive data set of particle intensities measured at 1 AU over the last three solar cycles, (2) successive launch dates for the mission traveling close to the Sun over the time interval spanned by our data set, and (3) appropriate radial dependences to extrapolate fluences and peak intensities measured at 1 AU to the heliocentric radial distance of the mission at each specific time, we generate distributions of both mission-integrated fluences and maximum peak intensities. From these distributions we extract the values of mission-integrated fluence and maximum peak intensity at a required confidence level. Results of this method applied to the specific case of the nominal prime mission of Solar Probe Plus are shown.

  • Cardiac Arrhythmogenesis and Temperature

    Fast processes in cardiac electrophysiology are often studied at temperatures lower than physiological. Extrapolation of values is based on widely accepted Q10 (Arrhenius) model of temperature dependence (ratio of kinetic properties for a 10degC change in temperature). In this study, we set out to quantify the temperature dependence of essential parameters that define spatiotemporal behavior of cardiac excitation. Additionally, we examined temperature's effects on restitution dynamics. We employed fast fluorescence imaging with voltage-and calcium-sensitive dyes in neonatal rat cardiomyocyte sheets. Conduction velocity (CV), calcium transient duration (CTD), action potential duration (APD) and wavelength (W=CV*duration) change as functions of temperature were quantified. Using 24degC as a reference point, we found a strong temperature-driven increase of CV (Q10=2.3) with smaller CTD and APD changes (Q10=1.33, 1.24, respectively). The spatial equivalents of voltage and calcium duration, wavelength, were slightly less sensitive to temperature with Q10=2.05 and 1.78, respectively, due to the opposing influences of decreasing duration with increased velocity. More importantly, we found that Q10 varies as a function of diastolic interval. Our results indicate the importance of examining temperature sensitivity across several frequencies. Armed with our results, experimentalists and modelers alike have a tool for reconciling different environmental conditions. In a broader sense, these data help better understand thermal influences on arrhythmia development or suppression such as during hibernation or cardiac surgery

  • Interpolation and extrapolation techniques based Neural Network in estimating the missing ionospheric TEC data

    This paper investigates the capabilities of Neural Network (NN) application in estimating the missing ionospheric total electron content (TEC) data via interpolation and extrapolation methods. TEC is an important parameter that describes the state of the ionosphere. A multilayer feed-forward network with a back propagation algorithm is applied to estimate the TEC over Parit Raja (Lat. 1°52'N, Long. 103°06'E) an equatorial latitude station in Malaysia. The solar and magnetic indices, seasonal variation as well as diurnal variation are used as the input spaces in the NN to estimate the missing GPS TEC. The studies period is based on short term data during the medium solar activity period from 2005 to 2006. Normalized RMSE, RMSE and relative correction are computed for both methods to evaluate the capability of NN to interpolate and extrapolate the missing data. The results show that NN is able to interpolate the missing TEC data within the input range better than extrapolating the missing data outside the input range. The NN2 model finds hard to extrapolate the missing TEC data especially during the night hours, where the GPS TEC values are underestimated. Overall the relative correction of NN1 model is above 90% while for NN2 is below 90% for all ranges of missing rate.

  • A time-marching scheme for analyzing transient scattering from nonplanar doubly periodic structures

    The paper presents a novel marching-on-in-time (MOT) based scheme for solving a time domain integral equation (TDIE) pertinent to the analysis of plane wave scattering from (potentially nonlinearly loaded) nonplanar doubly periodic structures. Historically, the analysis of transient scattering from doubly periodic structures has been carried out predominately using FDTD methods. Unfortunately, when the periodic structure is excited by obliquely incident fields, noncausal terms enter the FDTD update equations (unless specific measures are taken). Our recently developed a Floquet wave-based TDIE solver (Chen, N.-W. et al., IEEE APS Int. Symp., 2003) expands fields generated by quiescent and bandlimited periodic currents into time domain Floquet waves. We now present an improvement of that scheme aimed at rendering the solver applicable to nonplanar structures. Specifically, it introduces a scheme for evolving TDFW mode amplitudes along one-dimensional domains that permits their efficient evaluation not only on the source plane, but also removed from it. The proposed scheme evolves individual TDFWs using a spectral scheme supplemented with Huygen based boundary conditions. The resulting scheme applies without difficulty to nonplanar doubly periodic structures comprising PEC elements and sculptured dielectric substrates.

  • First-order optimal reduced-delay sample-data holds

    A data-holding scheme whose phase delay is significantly less than that of the usual zero-order hold (ZOH) is presented. The improvement is achieved by means of simple additional software, and a standard ZOH device is employed.
