Tell Me More! Towards Implicit User Intention Understanding of Language Model Driven Agents
Current language model-driven agents often lack mechanisms for effective user
participation, which is crucial given the vagueness commonly found in user
instructions. Although adept at devising strategies and performing tasks, these
agents struggle with seeking clarification and grasping precise user
intentions. To bridge this gap, we introduce Intention-in-Interaction (IN3), a
novel benchmark designed to inspect users' implicit intentions through explicit
queries. Next, we propose the incorporation of model experts as the upstream in
agent designs to enhance user-agent interaction. Employing IN3, we empirically
train Mistral-Interact, a powerful model that proactively assesses task
vagueness, inquires user intentions, and refines them into actionable goals
before starting downstream agent task execution. Integrating it into the XAgent
framework, we comprehensively evaluate the enhanced agent system regarding user
instruction understanding and execution, revealing that our approach notably
excels at identifying vague user tasks, recovering and summarizing critical
missing information, setting precise and necessary agent execution goals, and
minimizing redundant tool usage, thus boosting overall efficiency. All the data
and codes are released.Comment: 26 pages, 5 tables, 6 figure
Risk-sharing and probabilistic network structure
This paper studies the impact of a probabilistic risk-sharing network structure on the optimal portfolio composition. We show that, even assuming identical agents, we are able to differentiate their optimal risk-choice once we assume the link-structure defining their relationship probabilistic. In particular, the final agent's portfolio composition is function of his location in the network. If we assume positive asset-correlation coefficients, the relative location of a player in the graph influences his risk-behaviour as much as those of his direct and indirect partners in a not-straightforward way. We analyse also two potential "centrality measures" able to select the key-player in the risk-sharing network. The findings may help to select the "central" agent in a risk-sharing community and to forecast the risk-exposure of the players. Finally, this paper may explain natural differences between identical rational agents' choices emerging in a probabilistic network setup
Trading behavior and excess volatility in toy markets
We study the relation between the trading behavior of agents and volatility
in toy markets of adaptive inductively rational agents. We show that excess
volatility, in such simplified markets, arises as a consequence of {\em i)} the
neglect of market impact implicit in price taking behavior and of {\em ii)}
excessive reactivity of agents. These issues are dealt with in detail in the
simple case without public information. We also derive, for the general case,
the critical learning rate above which trading behavior leads to turbulent
dynamics of the market.Comment: 14 pages, 4 figures, minor change
Conformity-Driven Agents Support Ordered Phases in the Spatial Public Goods Game
We investigate the spatial Public Goods Game in the presence of
fitness-driven and conformity-driven agents. This framework usually considers
only the former type of agents, i.e., agents that tend to imitate the strategy
of their fittest neighbors. However, whenever we study social systems, the
evolution of a population might be affected also by social behaviors as
conformism, stubbornness, altruism, and selfishness. Although the term
evolution can assume different meanings depending on the considered domain,
here it corresponds to the set of processes that lead a system towards an
equilibrium or a steady-state. We map fitness to the agents' payoff so that
richer agents are those most imitated by fitness-driven agents, while
conformity-driven agents tend to imitate the strategy assumed by the majority
of their neighbors. Numerical simulations aim to identify the nature of the
transition, on varying the amount of the relative density of conformity-driven
agents in the population, and to study the nature of related equilibria.
Remarkably, we find that conformism generally fosters ordered cooperative
phases and may also lead to bistable behaviors.Comment: 13 pages, 5 figure
The Emergence of Norms via Contextual Agreements in Open Societies
This paper explores the emergence of norms in agents' societies when agents
play multiple -even incompatible- roles in their social contexts
simultaneously, and have limited interaction ranges. Specifically, this article
proposes two reinforcement learning methods for agents to compute agreements on
strategies for using common resources to perform joint tasks. The computation
of norms by considering agents' playing multiple roles in their social contexts
has not been studied before. To make the problem even more realistic for open
societies, we do not assume that agents share knowledge on their common
resources. So, they have to compute semantic agreements towards performing
their joint actions. %The paper reports on an empirical study of whether and
how efficiently societies of agents converge to norms, exploring the proposed
social learning processes w.r.t. different society sizes, and the ways agents
are connected. The results reported are very encouraging, regarding the speed
of the learning process as well as the convergence rate, even in quite complex
settings
Continuum time limit and stationary states of the Minority Game
We discuss in detail the derivation of stochastic differential equations for
the continuum time limit of the Minority Game. We show that all properties of
the Minority Game can be understood by a careful theoretical analysis of such
equations. In particular, i) we confirm that the stationary state properties
are given by the ground state configurations of a disordered (soft) spin
system; ii) we derive the full stationary state distribution; iii) we
characterize the dependence on initial conditions in the symmetric phase and
iv) we clarify the behavior of the system as a function of the learning rate.
This leaves us with a complete and coherent picture of the collective behavior
of the Minority Game. Strikingly we find that the temperature like parameter
which is introduced in the choice behavior of individual agents turns out to
play the role, at the collective level, of the inverse of a thermodynamic
temperature.Comment: Revised version (several new results added). 12 pages, 5 figure
On the Micro-foundations of Money: The Capitol Hill Baby-Sitting Co-op.
This paper contributes to the micro-foundation of money in centralized markets with idiosyncratic uncertainty. It shows existence of stationary monetary equilibria and ensures that there is an optimum quantity of money. The rational solution of our model is compared with actual behavior in a laboratory experiment. The experiment gives support to the theoretical approach.micro foundations of money; optimal quantity of money
