Summary
This study models the emergence of signaling conventions using multi-agent reinforcement learning. Population renewal in dense networks enables efficient language formation, avoiding local consensus traps.
Area of Science:
- Computational Linguistics
- Artificial Intelligence
- Game Theory
Background:
- Emergence of signaling conventions, like language, is a complex, interdisciplinary problem.
- Existing research uses diverse assumptions and methodologies, lacking a unifying explanation.
Purpose of the Study:
- To examine the formation of signaling conventions within a multi-agent reinforcement learning (MARL) framework.
- To investigate how network structure and population dynamics influence the emergence of consensus in signaling systems.
Main Methods:
- Utilized a MARL model to simulate agents forming signaling conventions.
- Analyzed agent interaction networks, including complete graphs, dense random graphs, and finite-dimensional lattices.
- Introduced population renewal mechanisms to observe their effect on consensus formation.
Main Results:
- Global consensus and efficient signaling (unique object-word mappings) emerged in complete or dense random graphs.
- Finite-dimensional lattices led to disordered configurations and only local consensus.
- Population renewal, coupled with superlinear reinforcement, overcame local traps and enhanced efficient signaling.
Conclusions:
- Network topology significantly impacts the formation of global signaling conventions.
- Population renewal is crucial for achieving efficient and unified signaling systems in structured environments.
- MARL provides a viable framework for understanding the evolution of communication.

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Positive and negative reinforcement are key concepts in operant conditioning, a learning process where the consequences of a behavior affect the likelihood of that behavior being repeated.
Positive reinforcement occurs when a behavior is followed by the presentation of a rewarding stimulus, increasing the frequency of that behavior. For example:

When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

The corrosion of steel reinforcement within concrete is a process influenced by the material's inherent properties and external factors. The high pH level of around 13, provided by calcium hydroxide present in concrete, initially protects the steel reinforcement by promoting the formation of a passive iron oxide layer on its surface.
However, over time and under certain conditions like carbonation, chloride ingress, and cracking this protective state can be compromised. Steel has areas with...

Positive reinforcement is a powerful method for teaching new behaviors to both animals and humans. B.F. Skinner demonstrated this with his experiments using rats in a Skinner box. When a rat pressed a lever, it received a food pellet. This immediate reward encouraged the rat to repeat the behavior. This method, where a reward follows every instance of the behavior, is known as continuous reinforcement. It is highly effective for establishing new behaviors quickly.
Once a behavior is learned,...

Reinforced concrete is a composite material used extensively in construction, combining the compressive strength of concrete with the tensile strength of steel. This synergy is essential as concrete, while excellent at resisting compression, is weak under tension. Steel bars, or rebars, are embedded in the concrete to handle these tensile forces. The choice of steel is strategic; it shares a similar coefficient of thermal expansion with concrete, which ensures uniformity in response to...
