Parallel Hierarchical Genetic Algorithm for Scattered Data Fitting through B-Splines
Applied Sciences, 2019 Curve fitting to unorganized data points is a very challenging problem that arises in a wide variety of scientific and engineering applications. Given a set of scattered and noisy data points, the goal is to construct a curve that corresponds to the best

Noise reduction method of shearer’s cutting sound signal under strong background noise
Measurement + Control, 2022 In coal and rock recognition technology, the acquisition of sound signals is affected by background noise. It is challenging to extract cutting features and accurately identify cutting patterns effectively.

Entropy, 2021 We present a case study applying hierarchical Bayesian estimation on high-throughput protein melting-point data measured across the tree of life. We show that the model is able to impute reasonable melting temperatures even in the face of unreasonably ...

Curve reconstruction from noisy samples
Proceedings of the nineteenth annual symposium on Computational geometry, 2003 The paper presents a new algorithm to reconstruct a collection of disjoint smooth closed curves from noisy samples. A probabilistic model of noisy samples is proposed. Moreover it is proved that the reconstruction is faithful with probability close to 1 as the number of samples increases.

A noisy principal component analysis for forward rate curves [PDF]
European Journal of Operational Research, 2015 Principal Component Analysis (PCA) is the most common nonparametric method for estimating the volatility structure of Gaussian interest rate models. One major difficulty in the estimation of these models is the fact that forward rate curves are not directly observable from the market so that non-trivial observational errors arise in any statistical ...

Detecting Faint Curved Edges in Noisy Images [PDF]
, 2010 A fundamental question for edge detection is how faint an edge can be and still be detected. In this paper we offer a formalism to study this question and subsequently introduce a hierarchical edge detection algorithm designed to detect faint curved edges in noisy images. In our formalism we view edge detection as a search in a space of feasible curves,
