The Response Shift Paradigm to Quantify Human Trust in AI Recommendations

no code implementations16 Feb 2022 Ali Shafti, Victoria Derks, Hannah Kay, A. Aldo Faisal

Explainability, interpretability and how much they affect human trust in AI systems are ultimately problems of human cognition as much as machine learning, yet the effectiveness of AI recommendations and the trust afforded by end-users are typically not evaluated quantitatively.

Bayesian Distributional Policy Gradients

no code implementations20 Mar 2021 Luchen Li, A. Aldo Faisal

Distributional Reinforcement Learning (RL) maintains the entire probability distribution of the reward-to-go, i. e. the return, providing more learning signals that account for the uncertainty associated with policy performance, which may be beneficial for trading off exploration and exploitation and policy learning in general.
