Computer-aided diagnosis of lung nodule using gradient tree boosting and Bayesian optimization
, 2017 We aimed to evaluate computer-aided diagnosis (CADx) system for lung nodule classification focusing on (i) usefulness of gradient tree boosting (XGBoost) and (ii) effectiveness of parameter optimization using Bayesian optimization (Tree Parzen Estimator,

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Mathematical Biosciences and Engineering, 2020 For some real-world problems, it is desirable to find multiple global optima as many as possible. The multimodal optimization approach which finds multiple optima in a single run shows significant difference with the single modal optimization approach ...

Local search efficiency when optimizing unimodal pseudoboolean functions
Informatica, 1998 Summary: This work is a continuation of our previous papers devoted to the exploration of the regular search procedures efficiency in binary search spaces. Here, we formulate the problem in a rather general form as a problem of optimization of a unimodal pseudo-Boolean function given implicitly and obtain analytical estimates of the expected time of a ...
