We propose <strong>Odin</strong> (<strong>O</strong>riented <strong>d</strong>ual-module <strong>in</strong>tegration), a new architecture that injects graph structure into Transformers at selected depths through an oriented dual-module mechanism. Unlike message-passing GNNs, Odin does not rely on multi-hop diffusion; instead, multi-hop structures are integrated at specific Transformer layers, yielding low-, mid-, and high-level structural abstraction aligned with the model’s semantic hierarchy. Because aggregation operates on node-specific [CLS] representations induced by textual tokens, Odin mitigates over-smoothing by preventing the iterative diffusion of homogeneous hidden states, and decouples structural abstraction from neighborhood size or graph topology. We further establish that Odin’s expressive power strictly contains that of both pure Transformers and GNNs. To make the design efficient in large-scale or low-resource settings, we introduce Light Odin, a lightweight variant that preserves the same layer-aligned structural abstraction for faster training and inference. Experiments on multiple text-rich graph benchmarks show that Odin achieves state-of-the-art accuracy, while Light Odin delivers competitive performance with significantly reduced computational cost.

In such settings, domain adaptation (DA) becomes especially difficult, as conventional methods often assume moderate divergence between source and target domains and overlook structural noise and data heterogeneity. These assumptions lead to performance degradation and instability when applied to high-variance scenarios. To address this, we propose a robust DA framework that leverages the expressive power of Gram matrices and the flexibility of Optimal Transport (OT) to align distributions while preserving intra-domain structure. Unlike traditional OT methods, which rely primarily on pairwise geometric distances and often ignore higher-order feature dependencies, our approach embeds Gram-based similarity networks to model relational patterns within and across domains. This enables the capture of semantic consistency beyond mere pointwise alignment. A key innovation of our method is the introduction of a low-rank constraint on the Gram matrix, which acts as a structural regularizer to suppress noise and highlight dominant data subspaces. Traditional OT formulations are susceptible to corruption in high-variance settings, as they treat all feature dimensions equally and can overfit to noisy or outlier-dominated regions. In contrast, our rank-constrained transport plan selectively emphasizes coherent, low-dimensional structures within the source domain, effectively filtering out corrupted subspaces and enhancing the robustness of cross-domain alignment. Experimental results across multiple benchmarks demonstrate that our approach significantly improves adaptation robustness, achieving an average accuracy of 89.36% on Office-Caltech, with gains of +3.85% on Office-Home, +2.5% on DomainNet, and +5.08% on the imbalanced VisDA dataset.</div></div>","PeriodicalId":19268,"journal":{"name":"Neurocomputing","volume":"675 ","pages":"Article 132965"},"PeriodicalIF":6.5,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146172896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, this paper introduces CaPGNN, a novel parallel full-batch GNN training framework on single server with multi-GPU. Firstly, considering the fact that the number of remote vertices in a partition is often greater than or equal to the number of local vertices and there may exist many duplicate vertices, we propose a joint adaptive caching algorithm that leverages both CPU and GPU memory, integrating lightweight cache update and prefetch techniques to effectively reduce redundant communication costs. Furthermore, taking into account the varying computational and communication capabilities among GPUs, we propose a communication- and computation-aware heuristic graph partitioning algorithm inspired by graph sparsification. Additionally, we implement a pipeline to overlap computation and communication. Extensive experiments show that CaPGNN improves training efficiency by up to 18.98x and reduces communication costs by up to 99%, with minimal accuracy loss or even accuracy improvement in some cases.

However, storing examples from previous tasks increases memory usage and raises privacy concerns. Recently, prompt-based methods have emerged as a promising alternative, as they do not rely on storing past samples. Despite this progress, current prompt-based techniques face several core challenges in CRE, particularly in accurately identifying task identities and mitigating catastrophic forgetting. Existing prompt selection strategies often suffer from inaccuracies, lack robust mechanisms to prevent forgetting in shared parameters, and struggle to handle both cross-task and within-task variations. In this paper, we propose <strong>WAVE++</strong>, a novel approach inspired by the connection between prefix-tuning and mixture of experts. Specifically, we introduce task-specific prompt pools that enhance flexibility and adaptability across diverse tasks while avoiding boundary-spanning risks; this design more effectively captures both within-task and cross-task variations.

Moreover, we integrate a generative model to consolidate prior knowledge within the shared parameters, thereby removing the need for explicit data storage.

This bias makes them vulnerable to image corruptions, domain shifts, and adversarial perturbations, posing significant challenges for real-world deployment, especially in safety-critical and industrial applications. Despite its significance, texture bias in object detection remains largely underexplored. To address this gap, we first conduct a comprehensive analysis of texture bias across multiple widely-used CNN-based detection architectures, demonstrating the widespread presence and detrimental impact of this issue. Motivated by these findings, we propose a simple yet effective method, TexDrop, to increase shape bias in CNNs and therefore improve their accuracy and robustness. Specifically, TexDrop randomly drops out the texture and color of the training images through straightforward edge detection, forcing models to learn to detect objects based on their shape, thus increasing shape bias. Unlike prior approaches that require architectural modifications, extensive additional training data or complex regularization schemes, TexDrop is model-agnostic, easy to integrate into existing training pipelines, and incurs negligible computational overhead. Intensive experiments on Pascal VOC, COCO, and various corrupted COCO datasets demonstrate that TexDrop not only improves detection performance across multiple architectures but also consistently enhances robustness against various image corruptions and texture variations. Our study provides empirical insights into texture dependence in object detectors and contributes a practical solution for developing more robust and reliable object detection systems in real-world applications.</div></div>","PeriodicalId":19268,"journal":{"name":"Neurocomputing","volume":"675 ","pages":"Article 132931"},"PeriodicalIF":6.5,"publicationDate":"2026-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146147230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
