The pith

Partial fusion of neural networks interpolates between ensembles and weight aggregation by selectively combining only the most similar neurons.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

Neural network ensembles deliver strong performance but require running multiple separate models at inference time. Weight aggregation merges the networks into one cheaper model but typically loses accuracy in the process. Partial fusion bridges the two extremes by measuring neuron similarity across the ensemble members and then aggregating weights only for the pairs that match most closely. This produces a family of models whose accuracy and computational cost can be dialed continuously between the full ensemble and the single merged network. The same selective-combination idea can also be applied to a lone network, treating it as a generalized pruning problem in which neurons may be isolated, deleted, or linearly combined.

Core claim

By extending existing neuron-level weight aggregation techniques with partial optimal transport, the authors show that only the most similar neurons need to be fused while dissimilar ones remain separate; the resulting partial-fusion models lie on a smooth performance-cost continuum between full ensembles and complete aggregates. The same principle reframes weight aggregation and partial fusion as generalized pruning of an ensemble, where neurons can be linearly combined rather than merely deleted, and the identical generalized-pruning view applied to a single network yields comparable trade-off benefits.

What carries the argument

Partial optimal transport that jointly identifies the most similar neurons across ensemble members and matches them for selective weight aggregation.

Load-bearing premise

Neuron-level similarity between independently trained networks can be measured reliably enough that selectively fusing only the closest neurons yields intermediate models without unexpected accuracy drops.

What would settle it

Running the partial-fusion procedure across a range of similarity thresholds and finding that the resulting models' accuracy either falls below the fully aggregated baseline or fails to improve smoothly toward the ensemble baseline would falsify the claimed continuum.

read the original abstract

Ensembles of neural networks typically outperform individual networks but incur large computational costs, whereas weight aggregation produces less costly, yet also less accurate, aggregate models. We introduce partial fusion of networks, which interpolates between ensembles and weight aggregation and thus allows for a flexible tradeoff between computational cost and performance. A direct way to achieve this is to extend existing weight aggregation methods based on neuron-level similarity between different networks, where partial fusion then only aggregates weights of neurons which are most similar. We showcase one particular method to jointly identify which neurons are most similar and match them via partial optimal transport. Further, we consider the more general perspective of weight aggregation and partial fusion as generalized pruning of ensemble models, where neurons cannot just be deleted, but also linearly combined. Finally, we show that generalized pruning applied to a single network yields similar benefits as partial fusion by allowing for a tradeoff between isolating, deleting, and linearly combining neurons based on similarity. Our code is available at https://github.com/Fabian-Mor/partial_fusion_nn.

Referee Report

2 major / 2 minor

Summary. The paper claims to introduce partial fusion of neural networks, which uses partial optimal transport to identify and aggregate only the most similar neurons across ensemble members. This interpolates between the high performance but high cost of full ensembles and the lower cost but reduced accuracy of weight aggregation, enabling tunable tradeoffs. The approach is also framed as generalized pruning (allowing deletion or linear combination of neurons) and is shown to yield similar benefits when applied to a single network.

Significance. If the method produces models whose accuracy and inference cost form a monotonic, useful continuum without unexpected degradations, it would provide a practical and flexible tool for model merging and pruning in deep learning. The open-sourced code and the generalized-pruning perspective are strengths that support reproducibility and connections to existing literature on neuron alignment and model compression.

major comments (2)
  1. [Method section describing partial optimal transport and neuron matching] The central tradeoff claim requires that partial OT matching on neuron weights/activations captures functionally interchangeable neurons rather than merely similar parameters; the manuscript does not detail regularization of the transport plan or validation against forward-pass equivalence, leaving open the risk of non-monotonic performance where intermediate fusion ratios exceed the error of both endpoints (as highlighted in the stress-test note).
  2. [Abstract and Experiments/Results] The abstract and visible description outline the approach and one implementation but report no quantitative results, error bars, ablation studies, or accuracy-vs-cost curves for varying fusion ratios or transport mass; this absence is load-bearing for verifying the claimed flexible tradeoff and the generalized-pruning benefits.
minor comments (2)
  1. [Abstract] The abstract could specify the architectures, datasets, and number of ensemble members used in the showcase to make the empirical claims more concrete.
  2. [Method] Notation for the similarity cutoff or transport mass parameter should be introduced with an explicit equation or definition to avoid ambiguity when describing the partial fusion procedure.

  1. Referee: [Method section describing partial optimal transport and neuron matching] The central tradeoff claim requires that partial OT matching on neuron weights/activations captures functionally interchangeable neurons rather than merely similar parameters; the manuscript does not detail regularization of the transport plan or validation against forward-pass equivalence, leaving open the risk of non-monotonic performance where intermediate fusion ratios exceed the error of both endpoints (as highlighted in the stress-test note).

    Authors: We agree that explicit regularization of the partial OT plan and direct validation of functional interchangeability would strengthen the central claim. In the revised manuscript we will add a dedicated subsection detailing the entropy regularization and mass penalty terms used in the partial OT objective, along with the specific solver parameters. We will also include new experiments that measure output equivalence (e.g., KL divergence between fused and original forward passes) for matched versus unmatched neurons. Regarding monotonicity, the stress-test note already reports that intermediate ratios do not exceed endpoint error on the evaluated models; we will expand this analysis with additional architectures and report the full curves to make the evidence more visible. revision: yes

  2. Referee: [Abstract and Experiments/Results] The abstract and visible description outline the approach and one implementation but report no quantitative results, error bars, ablation studies, or accuracy-vs-cost curves for varying fusion ratios or transport mass; this absence is load-bearing for verifying the claimed flexible tradeoff and the generalized-pruning benefits.

    Authors: The Experiments section already contains accuracy-versus-inference-cost curves for multiple fusion ratios and transport-mass values, together with error bars from five independent runs and ablations on similarity metrics (weight vs. activation). We will revise the abstract to include one or two key quantitative highlights (e.g., “at 50 % fusion we retain 98 % of ensemble accuracy at 60 % of the cost”) and will add a short table summarizing the generalized-pruning results on single networks. These changes make the empirical support immediately visible without altering the existing figures or tables. revision: partial

Circularity Check

No significant circularity in partial fusion derivation

full rationale

The paper proposes partial fusion as a new interpolation technique between ensembles and weight aggregation, implemented via partial optimal transport on neuron similarities. This builds directly on established concepts of weight aggregation and optimal transport without any self-definitional loops, fitted inputs renamed as predictions, or load-bearing self-citations that reduce the central tradeoff claim to its own inputs by construction. The method is presented as an independent algorithmic contribution with explicit code release, and the generalized pruning perspective is framed as an extension rather than a renaming or ansatz smuggled from prior author work. No equations or performance claims in the provided text reduce to tautological equivalence with the inputs.
