EVOLUTIONARY CONTEXTUAL BANDITS

This abstract first appeared for US patent application 20250068932 titled 'EVOLUTIONARY CONTEXTUAL BANDITS

Original Abstract Submitted

a method for solving a contextual bandit problem using an evolution linear thompson sampling (elints) algorithm is provided, wherein the method includes identifying a contextual bandit problem having exploration parameters and feature subsets, initializing a population of genomes for use with the exploration parameters and the feature subset, initializing exploration parameter values and a random feature subset, calculating an expected reward using the exploration parameters and the feature subsets, choosing an action arm a(t), observing a reward r(t) and update a cumulative reward, selecting a subset of existing genomes based on the cumulative and replacing one or more of the existing genomes with newly created offspring genomes.
