Gradient Bias to Solve the Generalization Limit of Genetic Algorithms Through Hybridization with Reinforcement Learning

Genetic Algorithms have recently been successfully applied to the Machine Learning framework, being able to train autonomous agents and proving to be valid alternatives to state-of-the-art Reinforcement Learning techniques. Their attractiveness relies on the simplicity of their formulation and stability of their procedure, making them an appealing choice for Machine Learning applications where the complexity and instability of Deep Reinforcement Learning techniques is still an issue. However, despite their apparent potential, the classic formulation of Genetic Algorithms is unable to solve Machine Learning problems in the presence of high variance of the fitness function, which is common in realistic applications.
