TrustFormer is a task‑specific framework that evaluates trust across multiple dimensions in dynamic collaborative systems. It synchronizes heterogeneous trust data using task identifiers and timestamps, then applies cross‑temporal and cross‑dimensional attention to model both temporal dynamics and inter‑dimensional correlations. By combining these multi‑dimensional trust profiles, the system selects optimal collaborators and achieves a 40.8% improvement in trust evaluation accuracy over existing methods.

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.

The paper introduces a bidirectional Mamba-enabled model (BM) for long‑term behavioral evaluation of devices in collaborative tasks. By constructing short‑time‑slot graphs of device interactions and aggregating behavioral features, BM integrates forward and backward temporal dependencies across all intervals. Experiments show that BM outperforms baseline methods, improving the accuracy of selecting trustworthy collaborators to maximize task completion value.

The paper introduces a systematic benchmark for evaluating explainable methods that attribute temporal interactions in sequential recommendation systems. Using a dual-model masking metric, it assesses ten XAI techniques across CNN, Transformer, SASRec, and BERT4Rec backbones on KuaiRand and MovieLens datasets, revealing that gradient-based methods like GradientSHAP and Integrated Gradients are the most faithful and robust. It also finds that raw attention weights are unreliable, while gradient-weighted attention works better on short sequences but degrades on longer horizons, and that faithful methods capture genuine task structure rather than recency or popularity bias.
