Application of Hopfield Networks to Character AI in Digital games

Abstract

Hopfield networks function as associative memory devices, and this research aims to use Hopfield networks to recall previously memorized image patterns in the dynamic environment of a digital game, and have the character AI perform actions in response. In this research, Hopfield networks are implemented as a character recognition function, and they are made to recognize the environment in a simple shooting game and take an action to defeat the enemy in response to the recognition. Such a recall mechanism in digital games should open up various possibilities for game design.
