Are Independently Estimated View Uncertainties Comparable? Unified Routing for Trusted Multi-View Classification

The paper introduces Trusted Multi-view learning with Unified Routing (TMUR), a method that separates view-specific evidence extraction from fusion arbitration in multi-view classification. TMUR employs view-private experts, a collaborative expert, and a unified router that assigns sample-level weights based on global context, along with soft load-balancing and diversity regularization to promote balanced and discriminative expert use. Experiments on 14 datasets show that TMUR consistently improves classification accuracy and reliability compared to 15 recent baselines.

Multi-View Trust Evaluation for Collaborator Selection via Evidential Deep Learning

The paper introduces Multi-View Evidential (MVE) learning for evaluating trustworthiness of collaborators in distributed systems. It models each task owner’s interaction as an independent view, uses the Mamba model to capture temporal trust dynamics, and applies evidential deep learning to quantify uncertainty. A dynamic fusion strategy then combines view-specific evidence to produce a final trust assessment, outperforming baselines in accuracy and task success rate.

Robust Dempster-Shafer Evidence Fusion with Chaos-Conflict Measurement and Historical-Experience Weighting

arXiv:2608. 13108v1 Announce Type: new Abstract: Multi-source evidence fusion under Dempster-Shafer theory faces two persistent challenges: existing conflict measures assess inter-evidence inconsistency and intra-evidence uncertainty independently, yielding incomplete evaluations, and current fusion methods evaluate evidence sources exclusively through instantaneous comparisns without exploiting their long-term reliability across diverse decision contexts.

Backbone-Adaptive Evidence Routing for Robust Pairwise LLM Judging

Backbone-Adaptive Evidence Routing (BAER) is a method that dynamically selects an evidence gathering protocol—evidence stacking, reliability-based expert routing, or candidate-blind reference verification—based on the judge backbone and benchmark during development, then locks that choice for testing. BAER maintains candidate symmetry, ensuring that swapping responses reverses preference but not its strength. In experiments across four benchmarks and two 8B judge backbones, BAER outperforms all compared methods, achieving the highest test accuracy in all eight conditions and improving over the strongest baseline by 0.87–7.32 points.

Class-wise Contribution Estimation via Logit Maximization for Federated Learning

The paper introduces CELM, a data‑free framework for federated learning that estimates class‑wise contribution by maximizing logits. It constructs a cross‑client evidence matrix to quantify each client’s competence and coverage for each class, then uses this matrix to compute weighted aggregation that upweights clients offering strong evidence for underrepresented classes. The method maintains stability through simplex constraints and momentum smoothing, and it is compatible with standard FL pipelines, showing improved robustness to class imbalance and heterogeneity on vision benchmarks.

TIER-MoE: Trust-Informed Expert Routing via Conditional Modality Risk for Multimodal Fusion in Biomedical Classification

arXiv:2607. 27289v1 Announce Type: new Abstract: The promise of multimodal fusion lies in combining complementary sources of evidence, yet more evidence does not always yield a better prediction.
