Effects of Stress and Genotype on Exploration-Exploitation Dynamics in Reinforcement Learning

Published on Feb 25, 20074878 Views

Stress and genetic background regulate different aspects of behavioral learning through the action of stress hormones and neuromodulators. Similarly, in reinforcement learning (RL) models, exploitatio
