Chat Bankman-Fried: an Exploration of LLM Alignment in Finance

1 code implementation1 Nov 2024 Claudia Biancotti, Carolina Camassa, Andrea Coletta, Oliver Giudice, Aldo Glielmo

Advancements in large language models (LLMs) have renewed concerns about AI alignment - the consistency between human and AI goals and values.

Privacy-Preserving Synthetically Augmented Knowledge Graphs with Semantic Utility

no code implementations16 Oct 2024 Luigi Bellomarini, Costanza Catalano, Andrea Coletta, Michela Iezzi, Pierangela Samarati

In this paper, we propose a novel framework to enable KGs sharing while ensuring that information that should remain private is not directly released nor indirectly exposed via derived knowledge, while maintaining the embedded knowledge of the KGs to support business downstream tasks.

Simulating the Economic Impact of Rationality through Reinforcement Learning and Agent-Based Modelling

2 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.
