The Optimal Bandwidth Parameter Selection in GPH Estimation [PDF]

Journal of Mathematics, 2021
In this paper, the optimal bandwidth parameter is investigated in the GPH algorithm. Firstly, combining with the stylized facts of financial time series, we generate long memory sequences by using the ARFIMA (1, d, 1) process.

Multi-Parameter AI-Based Bandwidth Compensation for Energy-Efficient 800G Transmission

Optical Fiber Communication Conference (OFC) 2023, 2023
We propose a novel energy-efficient AI-based bandwidth compensation technique that jointly optimizes Tx and Rx static filters. Experimental demonstration in a 800G system reveals gains of more than 1 dB when compared with typical digital pre-emphasis.

Estimating a Cosmological Mass Bias Parameter with Bootstrap Bandwidth Selection [PDF]

Journal of the Royal Statistical Society Series C: Applied Statistics, 2010
SummaryWe focus on selecting optimal bandwidths for non-parametric estimation of the two-point correlation function of a point pattern. We obtain these optimal bandwidths by using a bootstrap approach to select a bandwidth that minimizes the integrated squared error.
