Multi-view Graph Convolutional Network with Fully Leveraging Consistency via Granular-ball-based Topology Construction, Feature Enhancement and Interactive Fusion

The pith
A multi-view GCN with granular-ball topology, feature enhancement, and interactive fusion fully exploits inter-node, inter-feature, and inter-view consistency to improve semi-supervised node classification.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
MGCN-FLC fully utilizes three types of consistency via the following three modules to enhance learning ability: the topology construction module based on the granular ball algorithm, which clusters nodes into granular balls with high internal similarity to capture inter-node consistency; the feature enhancement module that improves feature representations by capturing inter-feature consistency; the interactive fusion module that enables each view to deeply interact with all other views, thereby obtaining more comprehensive inter-view consistency. Experimental results on nine datasets show that the proposed MGCN-FLC outperforms state-of-the-art semi-supervised node classification methods.
What carries the argument
The granular-ball-based topology construction module that clusters nodes into groups of high internal similarity, together with separate feature-enhancement and interactive-fusion steps.
If this is right
- Granular-ball clustering captures inter-node consistency without forcing an artificial choice of k as in KNN graphs.
- Feature enhancement raises embedding quality by enforcing consistency among features inside each view.
- Interactive fusion yields richer inter-view consistency than late-stage merging of separately convolved embeddings.
- The complete model records higher accuracy than prior semi-supervised node-classification methods across the nine evaluated datasets.
Where Pith is reading between the lines
- The same modular structure could extend to multi-view tasks such as clustering or link prediction where the three consistency types also appear.
- Granular-ball topology may reduce sensitivity to hyper-parameter choices that affect KNN-based graphs on varying data densities.
- The three consistency types appear complementary, suggesting that joint optimization of all three could yield further gains beyond the current sequential design.
Load-bearing premise
The three modules each deliver measurable, non-redundant gains over ordinary KNN-based multi-view GCN pipelines rather than arising from dataset-specific tuning.
What would settle it
An ablation experiment on the same nine datasets in which removing the granular-ball module, the feature-enhancement module, or the interactive-fusion module produces no drop in accuracy relative to the full model or to standard KNN baselines.

The effective utilization of consistency is crucial for multi-view learning. GCNs leverage node connections to propagate information across the graph, facilitating the exploitation of consistency in multi-view data. However, most existing GCN-based multi-view methods suffer from several limitations. First, current approaches predominantly rely on KNN for topology construction, where the artificial selection of the k value significantly constrains the effective exploitation of inter-node consistency. Second, the inter-feature consistency within individual views is often overlooked, which adversely affects the quality of the final embedding representations. Moreover, these methods fail to fully utilize inter-view consistency as the fusion of embedded representations from multiple views is often implemented after the intra-view graph convolutional operation. Collectively, these issues limit the model's capacity to fully capture inter-node, inter-feature and inter-view consistency. To address these issues, this paper proposes the multi-view graph convolutional network with fully leveraging consistency via GB-based topology construction, feature enhancement and interactive fusion (MGCN-FLC). MGCN-FLC can fully utilize three types of consistency via the following three modules to enhance learning ability:The topology construction module based on the granular ball algorithm, which clusters nodes into granular balls with high internal similarity to capture inter-node consistency;The feature enhancement module that improves feature representations by capturing inter-feature consistency;The interactive fusion module that enables each view to deeply interact with all other views, thereby obtaining more comprehensive inter-view consistency. Experimental results on nine datasets show that the proposed MGCN-FLC outperforms state-of-the-art semi-supervised node classification methods.

Referee Report
Summary. The paper proposes MGCN-FLC, a multi-view graph convolutional network that addresses limitations in existing GCN-based multi-view methods by introducing three modules: (1) granular-ball-based topology construction to capture inter-node consistency by clustering nodes with high internal similarity, (2) a feature enhancement module to capture inter-feature consistency within views, and (3) an interactive fusion module to enable deep inter-view interactions for comprehensive inter-view consistency. The method is evaluated on nine datasets for semi-supervised node classification, where it is claimed to outperform state-of-the-art approaches, supported by component-wise ablation studies showing incremental performance drops upon module removal.
Significance. If the experimental results and ablations hold, this work provides a practical and incremental improvement to multi-view GCNs by better exploiting multiple forms of consistency, with the granular-ball topology offering a data-driven alternative to KNN that may enhance robustness. The ablation evidence that each module contributes measurable gains strengthens the central claim, and the approach could be relevant for applications involving multi-view graph data such as social networks or bioinformatics.
major comments (1)
- [§4.3] §4.3, Ablation tables: While component-wise removals show performance drops, the paper does not report the number of random seeds or variance across runs for the main results and ablations; this makes it difficult to assess whether the reported gains (typically 1-3% accuracy) are statistically robust or sensitive to initialization.
minor comments (3)
- [§3.1] §3.1: The granular ball algorithm description would benefit from an explicit pseudocode or complexity analysis, as the clustering step's scalability with large node counts is not addressed.
- [Table 1] Table 1: Dataset statistics table lacks the number of views per dataset and average node degree, which are relevant for interpreting the multi-view GCN results.
- [§5] §5: The related work section could include a more direct comparison to recent granular computing or ball-based graph methods to better position the novelty.
Simulated Author's Rebuttal

Referee: [§4.3] §4.3, Ablation tables: While component-wise removals show performance drops, the paper does not report the number of random seeds or variance across runs for the main results and ablations; this makes it difficult to assess whether the reported gains (typically 1-3% accuracy) are statistically robust or sensitive to initialization.
Authors: We agree that reporting run statistics is necessary to establish robustness. In the revised version we will rerun all experiments (main results and ablations) using 10 independent random seeds, reporting mean accuracy together with standard deviation in the updated Table 2 (main results) and Table 3 (ablations). This will confirm that the observed 1–3 % gains are consistent across initializations rather than artifacts of a single run. revision: yes
Circularity Check
No significant circularity detected
full rationale
The paper presents an empirical architecture for multi-view GCNs consisting of granular-ball topology construction, feature enhancement, and interactive fusion modules. No closed-form derivations, predictions, or equations are provided that reduce to fitted parameters or self-citations by construction. Claims rest on experimental accuracy gains and ablations across nine datasets, with no load-bearing self-definitional steps, uniqueness theorems, or ansatzes imported via citation. The method is self-contained as an engineering proposal rather than a mathematical reduction.
