Smooth transition exponential smoothing [PDF]

open access: yesJournal of Forecasting, 2004
AbstractAdaptive exponential smoothing methods allow a smoothing parameter to change over time, in order to adapt to changes in the characteristics of the time series. However, these methods have tended to produce unstable forecasts and have performed poorly in empirical studies.

Nesterov Smoothing for Sampling Without Smoothness

open access: yes2023 62nd IEEE Conference on Decision and Control (CDC), 2023
We study the problem of sampling from a target distribution in $\mathbb{R}^d$ whose potential is not smooth. Compared with the sampling problem with smooth potentials, this problem is much less well-understood due to the lack of smoothness. In this paper, we propose a novel sampling algorithm for a class of non-smooth potentials by first approximating ...

Review of applications and surface smoothing mechanisms of optical waveguide devices

open access: yesJournal of Hebei University of Science and Technology, 2017
Optical waveguide devices are widely used in many fields and have good development prospects. But surface roughness of waveguide device induces a passive effect on the light transmission loss and the Q value of ring cavity, which restricts the ...

Smoothing and Clustering Guided Image Decolorization

open access: yesImage Analysis and Stereology, 2021
In this paper, we propose a new image decolorization method based on image clustering and weight optimization. First, we smooth the color image and cluster it into several classes and get the class centers.

Contexte théorique de la notion de discontinuité géographique

open access: yesCybergeo, 2002
Likeness and proximity are studied in the particular context of geographical discontinuity, in both clustered (bounded) and continuous spaces. First, likeness and proximity are linked: likeness could be spatial and/or social; moreover, social structures ...

Multitarget Tracking Using One Time Step Lagged Delta-Generalized Labeled Multi-Bernoulli Smoothing

open access: yesIEEE Access, 2020
Aiming at improving the tracking performance of the delta-generalized labeled multi-Bernoulli (δ-GLMB) filter, we present a one time step lagged δ-GLMB smoother in this work, which also inherently outputs targets trajectories and differs ...

Modified Smoothing Algorithm for Tracking Multiple Maneuvering Targets in Clutter

open access: yesSensors, 2022
This research work extends the fixed interval smoothing based on the joint integrated track splitting (FIsJITS) filter in the multi-maneuvering-targets (MMT) tracking environment.
