An Algorithm for Biometric Authentication Based on the Model of Non-Stationary Random Processes
نویسندگان
چکیده
We present a biometric authentication algorithm with 3 possible outputs: accept the claimed identity, reject the claimed identity, and no answer. The algorithm is based on the model of non–stationary random processes and transformations of realizations of the processes to q-ary vectors whose components are uniformly distributed over the set {0, . . . , q − 1}, where q is fixed. An application of the algorithm brings the false acceptance and the false rejection rates that do not depend on the probability distribution over the templates space and exponentially decrease with the number of independent biometric parameters available to an observer.

Some New Methods for Prediction of Time Series by Wavelets
Extended Abstract. Forecasting is one of the most important purposes of time series analysis. For many years, classical methods were used for this aim. But these methods do not give good performance results for real time series due to non-linearity and non-stationarity of these data sets. On one hand, most of real world time series data display a time-varying second order structure. On th...

In this paper, a new version of multi-objective differential evolution with dynamically adaptable mutation factor is used for Pareto optimization of a 5-degree of freedom vehicle vibration model excited by non-stationary random road profile. In this way, non-dominated sorting algorithm and crowding distance criterion have been combined to differential evolution with fuzzified mutation in order ...

متن کاملOptimal design of a vibration absorber for tremor control of arm in Parkinson's disease
Because the underlying physiology of pathological tremor in a Parkinson's patient is not well understood, the existing physical and drug therapies have not been successful in tremor treatment. Different mathematical modeling of such vibration has been introduced to investigate the problem and reduce the existing vibration. Most of the models have represented the induced vibration as a sinusoida...
متن کاملTracking performance of incremental LMS algorithm over adaptive distributed sensor networks
in this paper we focus on the tracking performance of incremental adaptive LMS algorithm in an adaptive network. For this reason we consider the unknown weight vector to be a time varying sequence. First we analyze the performance of network in tracking a time varying weight vector and then we explain the estimation of Rayleigh fading channel through a random walk model. Closed form relations a...
