Emotional State and Feedback-Related Negativity Induced by Positive, Negative, and Combined Reinforcement

open access: yesFrontiers in Psychology, 2021
Reinforcement learning relies on the reward prediction error (RPE) signals conveyed by the midbrain dopamine system. Previous studies showed that dopamine plays an important role in both positive and negative reinforcement.

Sample Efficient Reinforcement Learning with REINFORCE

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2021
Policy gradient methods are among the most effective methods for large-scale reinforcement learning, and their empirical success has prompted several works that develop the foundation of their global convergence theory. However, prior works have either required exact gradients or state-action visitation measure based mini-batch stochastic gradients ...

Adaptive Control with Approximated Policy Search Approach

open access: yesITB Journal of Engineering Science, 2010
Most of existing adaptive control schemes are designed to minimize error between plant state and goal state despite the fact that executing actions that are predicted to result in smaller errors only can mislead to non-goal states. We develop an adaptive

Comfort or hesitancy: A cross-sectional study of modifiable factors associated with co-vaccination behavior among United States and Canadian adults

open access: yesPreventive Medicine Reports
Objective: Co-vaccination, or receiving multiple vaccines at once, may improve vaccination uptake and reduce missed opportunities to vaccinate. Although generally considered safe and effective, co-vaccination is not well accepted outside of travel and ...
