Real‐Time and Rapid Dynamic Missile Identification Utilizing a TiOx Memristor Array
Advanced Intelligent Systems, EarlyView.Real‐time missile target identification is demonstrated using an artificial intelligence model based on step‐weighted long–short‐term memory networks and a TiOx memristor array. The approach classifies five projectile types with enhanced early‐stage prediction through data augmentation and custom training strategies. Achieving 94.4% accuracy, the model

Optimal Control Applications and Methods, Volume 47, Issue 1, Page 4-23, January/February 2026.ABSTRACT High‐level decision‐making for dynamical systems often involves performance and safety specifications that are activated or deactivated depending on conditions related to the system state and commands. Such decision‐making problems can be naturally formulated as optimization problems where these conditional activations are regulated by ...
