Synthetic objective function to improve the performance of DE – Initial study

2017 · AIP conference proceedings

In this initial study, the idea of synthesizing objective function during the evolution process is tested for the improvement of optimization performance of Differential Evolution (DE) algorithm. Since many of the real world problems require …

Performance comparison of differential evolution driving analytic programming for regression

2017

This research deals with the hybridization of symbolic regression open framework, which is Analytical Programming (AP) and Differential Evolution (DE) algorithm in the task of time series regression. This paper provides a closer insight into …

Depth estimation in half-space trees and feature range formulation for novelty detection

2026 · Information Sciences

Tree-based methods such as Isolation Forest (iForest) and Half-Space Trees (HS-Trees) are widely used for unsupervised anomaly detection due to their efficiency and scalability. However, the classical depth estimator $c(n)$, originally derived for iForest under …
