Density estimation is a fundamental task in statistics and machine learning that aims to estimate, from set of samples, the probability density function distribution generated them. There are different methods for addressing this problem but recently deep-neural have emerged as powerful alternative. This paper presents novel method neural based on matrices adaptive Fourier features. commonly us...
Knowing the number, area, and frequency of landslides occurred in each area has a prominent role in the long-term evolution of area dominated by landslides and can be used for analyzing of susceptibility, hazard, and risk. In this regard, the current research is trying to consider identified landslides size probability in the Pivejan Watershed, Razavi Khorasan Province. In the first step, lands...
This paper presents a novel method of spectral envelope estimation and representation. Despite much sophisticated work in this area, estimating an appropriate envelope is still difficult. We therefore propose an F0-adaptive multi-frame integration analysis method for estimating spectral envelopes with appropriate shape and high temporal resolution. The method does not use pitch marks or phoneme...
A method is provided for scalar systems which uses FFTs and provides spectral factorization directly from the periodogram. The method is block recursive, providing better estimates as time progresses with more data available. Although spectral factorization is a mature technique, the current methods available are generally to slow to cope with acoustic problems of the scale discussed here
In robust nonparametric kernel regression context,weprescribemethod to select trimming parameter and bandwidth. Through solving estimating equations, we control outlier effect through combining weighting and trimming. We show asymptotic consistency, establish bias, variance properties and derive asymptotics. © 2016 Elsevier B.V. All rights reserved.
Present study took into account the relationship between surface soil moisture of intertidal zone and its spectral reflectance and the relationship between surface soil moisture and the relative elevation of intertidal zone to extract ‘ridges’. It can represent the main morphological character of radial sand ridges, and find specific spectral bands to diagnose much ‘drier’ points of sand ridges...
