Simulating the economic impact of rationality through reinforcement learning and agent-based modelling

no code implementations3 May 2024 Simone Brusatin, Tommaso Padoan, Andrea Coletta, Domenico Delli Gatti, Aldo Glielmo

We find that RL agents spontaneously learn three distinct strategies for maximising profits, with the optimal strategy depending on the level of market competition and rationality.

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).

INTAGS: Interactive Agent-Guided Simulation

no code implementations4 Sep 2023 Song Wei, Andrea Coletta, Svitlana Vyetrenko, Tucker Balch

To adapt to any environment with interactive sequential decision making agents, INTAGS formulates the simulator as a stochastic policy in reinforcement learning.

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.
