EvoTeam evolves the team and the rules of the team, not just the agents inside it
AspireAI community · arXiv
Existing multi-agent work mostly improves individual agents by refining their prompts, skills and execution strategies on task feedback, which does not necessarily produce better collaboration, and approaches that do evolve the collaboration level tend to constrain reorganization inside one shared structure while reusing interaction rules across incompatible team contexts. EvoTeam is a collaboration-centric framework that jointly evolves team organization, interaction rules and individual agent skills from execution experience, maintaining a library of reusable teams that it selects from or composes from, with collaboration experience accumulating within compatible team contexts while individual skills stay reusable across teams. It is evaluated across four benchmarks, and the implementation is public on GitHub under the DEEP-JLU organisation, though the repository had only 2 stars at the time of this write-up and the code carries an unusual non-standard environment file convention.

Two sparse-autoencoder analyses have resisted scaling: matching semantically similar features across layers, and compressing large feature circuits into interpretable supernodes. This paper argues both are the same underlying problem, estimating semantic distances between SAE features that sit on different activation manifolds. Its representation treats each feature not as a single decoder vector but as an activation-weighted distribution over the hidden states expressing it, projects those distributions into a shared reference space, and compares them with Wasserstein distance. The representation is proved invariant to activation rescaling and stable under perturbation, and recovers true matches under finite-sample margin conditions. Empirically it outperformed decoder-vector and LLM-based baselines and captured subtle functional distinctions between related features, and it compressed large feature circuits into interpretable supernodes automatically. The limitation is that this is interpretability tooling: the paper demonstrates better feature matching and circuit compression, not that downstream interpretability claims become more accurate.
