PREPARE-Playback RatE and Priority Adaptive BitRate Selection
IEEE Access, 2019 HAS (HTTP-based Adaptive Streaming) based on ABR (Adaptive Bitrate Rate selection) has become a prevalent solution to media transmission. In order to improve the performance of HAS, many studies focus on how to reduce the unfairness, the instability and ...

UNBIASED BANDWIDTH ESTIMATION IN COMMUNICATION PROTOCOLS
IFAC Proceedings Volumes, 2005 Abstract Heterogeneous communication networks with their variety of application demands, uncertain time-varying traffic load, and mixture of wired and wireless links pose several challenging problem in modeling and control. In this paper we focus on bandwidth estimation and elucidate why estimates based directly on bandwidth samples are biased ...

β-divergence loss for the kernel density estimation with bias reduced
Statistical Theory and Related Fields, 2021 In this paper, we investigate the problem of estimating the probability density function. The kernel density estimation with bias reduced is nowadays a standard technique in explorative data analysis, there is still a big dispute on how to assess the ...

Optimal Bandwidth Selection for Kernel Density Functionals Estimation
Journal of Probability and Statistics, 2015 The choice of bandwidth is crucial to the kernel density estimation (KDE) and kernel based regression. Various bandwidth selection methods for KDE and local least square regression have been developed in the past decade.

Bandwidth and Variance in Estimation of the Spectrum
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1958 SUMMARY This paper deals with the uncertainty principle that governs the behaviour of bandwidth and variance in the estimation of the spectrum of a stationary stochastic process. Lomnicki and Zaremba (1957) have tried to show that this principle is not valid. It will be shown below that their reasoning is not correct.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
