New Model Fusion Technique Improves Zero-Shot Performance

Researchers have developed a new neuron-centric approach to model fusion, addressing challenges posed by representational divergence in independently trained neural networks. This method frames fusion as a representation-matching problem, aligning intermediate neurons across models to approximate target representations. It incorporates neuron attribution scores to prioritize salient features and is applicable to various architectures, showing significant improvements, especially in zero-shot and non-IID data scenarios.

    Model Fusion via Retrofitting

    arXiv:2507.00037v2 Announce Type: replace-cross Abstract: Model fusion seeks to combine independently trained neural networks into a single model without retraining, but is complicated by representational divergence arising from permutation invariance, random initialization, and …
