New method merges neural networks with less widening

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method for merging pre-trained neural networks that reduces the need for significant model widening. This technique, based on reciprocal orthogonality, encourages the coexistence of models' computations within a merged network, promoting linear mode connectivity (LMC) even with smaller width expansions. The method has demonstrated success in merging models trained on different data distributions, where traditional weight matching methods falter, and the merged predictions closely approximate those of a logit ensemble of the original models.

    Permutation-Based Pre-trained Model Merging via Reciprocal Orthogonality

    arXiv:2611.13016v1 Announce Type: new Abstract: Ito et al. (2026) showed that sufficiently wide, independently trained neural networks can exhibit linear mode connectivity (LMC) with softmax temperature calibration, even without permutation. LMC means that a low-loss linear path …
