This paper resolves a discrepancy between sociolinguistic observations and AI simulations by demonstrating that population heterogeneity, specifically varied learning speeds among agents, allows larger groups to develop more structured communication systems. Introducing diversity enables larger populations to achieve improved speaker synchronization, negative entropy, compositionality, and generalization compared to homogeneous populations.
Key insights
- Population size effects on language quality are contingent on heterogeneity; larger groups only show benefits when agents have varying learning speeds.
- Introducing controlled asymmetry between speaker and listener learning speeds improves most language quality measures, suggesting role differentiation is beneficial.
- Greater diversity in learning speeds within a population amplifies the positive effects of larger populations on language structure and quality.
