LLM-driven Imitation of Subrational Behavior : Illusion or Reality?

no code implementations13 Feb 2024 Andrea Coletta, Kshama Dwarakanath, Penghang Liu, Svitlana Vyetrenko, Tucker Balch

We make an assumption that LLMs can be used as implicit computational models of humans, and propose a framework to use synthetic demonstrations derived from LLMs to model subrational behaviors that are characteristic of humans (e. g., myopic behavior or preference for risk aversion).

K-SHAP: Policy Clustering Algorithm for Anonymous Multi-Agent State-Action Pairs

no code implementations23 Feb 2023 Andrea Coletta, Svitlana Vyetrenko, Tucker Balch

Finally, by clustering the explanations we show that we are able to identify different agent policies and group observations accordingly.
