Free Agent in Agent-Based Mixture-of-Experts Generative AI Framework
This addresses the issue of real-time agent replacement for improved performance in multi-agent systems, though it is incremental as it builds on existing mixture-of-experts and reinforcement learning methods.
The paper tackles the problem of underperforming agents in multi-agent systems by introducing the RLFA algorithm, which dynamically replaces low-performing agents with better ones, resulting in sustained accuracy and quicker adaptation to emerging threats in applications like fraud detection.
Multi-agent systems commonly distribute tasks among specialized, autonomous agents, yet they often lack mechanisms to replace or reassign underperforming agents in real time. Inspired by the free-agency model of Major League Baseball, the Reinforcement Learning Free Agent (RLFA) algorithm introduces a reward-based mechanism to detect and remove agents exhibiting persistent underperformance and seamlessly insert more capable ones. Each agent internally uses a mixture-of-experts (MoE) approach, delegating incoming tasks to specialized sub-models under the guidance of a gating function. A primary use case is fraud detection, where RLFA promptly swaps out an agent whose detection accuracy dips below a preset threshold. A new agent is tested in a probationary mode, and upon demonstrating superior performance, fully replaces the underperformer. This dynamic, free-agency cycle ensures sustained accuracy, quicker adaptation to emerging threats, and minimal disruption to ongoing operations. By continually refreshing its roster of agents, the system fosters ongoing improvements and more resilient collaboration in multi-agent Generative AI environments.
