CoLLA (Collective Lifelong Learning Algorithm) introduces a decentralized multi-agent framework that enables networks of agents to collaboratively acquire knowledge across sequential tasks. This approach accelerates learning and improves initial task performance, demonstrating up to a 51.44% higher jumpstart improvement over single-agent lifelong learning methods on tested datasets.

Key insights

  • Collective learning among distributed agents, even without a central coordinator, leads to improved lifelong learning performance, including faster learning speeds and better asymptotic results, compared to individual agents.
  • The formulation of knowledge as factorized local dictionaries, synchronized through ADMM-based constraints, offers an effective and privacy-preserving mechanism for knowledge transfer in decentralized networks.
  • Network topology significantly impacts the rate of collective knowledge acquisition, with denser graph structures (e.g., complete graphs) generally facilitating faster learning and knowledge dissemination.
