The application of machine learning models to optimal TSP tour length estimation

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The traveling salesman problem (TSP) is a well‐known NP‐hard problem in combinatorial optimization, with numerous applications in logistics and elsewhere. This paper introduces a machine learning‐based approach to estimate the optimal tour length of the TSP, using linear regression, random forests (RF), and neural networks, including ...

Effect of Silane Incorporation on the Bonding Performance of Universal Adhesives to Dentin

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Purpose The effect of silane in universal adhesives (UAs) on dentin adhesion remains unclear. Therefore, this study evaluated the dentin bonding of UAs with and without silane immediately and after thermocycling. Materials and Methods Sixty‐four sound human molars were randomly assigned to eight groups according to silane incorporation (UAs ...

Effects of low‐pressure plasma and ytterbium fiber laser on zirconia surface properties and bond strength to gingiva‐colored composite

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate and compare the effects of surface activation by low‐pressure plasma (LPP) and surface texturing by ytterbium fiber laser (YFL) treatments on zirconia surface properties and shear bond strength (SBS) to a gingiva‐colored indirect composite under aged and non‐aged conditions.

Band‐Pass Filtering With High‐Dimensional Time Series. A Synthetic Indicator of the Medium‐to‐Long Run Component of Growth

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

Testing Distributional Granger Causality With Entropic Optimal Transport

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We develop a novel nonparametric test for Granger causality in distribution based on entropic optimal transport. Unlike classical mean‐based approaches, the proposed method directly compares the full conditional distributions of a response variable with and without the history of a candidate predictor.

The Accuracy Smoothness Dilemma in Prediction: A Novel Multivariate M‐SSA Forecast Approach

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT Forecasting presents a complex estimation challenge, as it involves balancing multiple, often conflicting, priorities and objectives. Conventional forecast optimization methods typically emphasize a single metric, such as minimizing the mean squared error (MSE), which may neglect other crucial aspects of predictive performance. To address this
