ConMoE: Expert-Pool Consolidation via Prototype Reassignment for MoE Compression

ConMoE presents a novel post-training compression method for Mixture-of-Experts language models that consolidates expert pools through prototype reassignment rather than pruning or weight merging. The train-free approach selectively retains pretrained experts as reusable prototypes and remaps original expert references to these prototypes, achieving competitive or superior performance on major MoE models while significantly reducing deployment memory requirements.

Learning Context-Conditioned Predicate Semantics via Prototype Feedback

Researchers introduce AlignG, a machine learning approach that improves scene graph generation by enabling predicates to adapt their meanings based on image context rather than remaining static. The method uses prototype feedback to recalibrate predicate representations while preventing semantic drift, demonstrating measurable performance improvements on standard benchmarks.

Respecting Modality Gap in Post-hoc Out-of-distribution Detection with Pre-trained Vision-Language Models

Researchers challenge the standard approach of using text embeddings as class prototypes in out-of-distribution detection with vision-language models, demonstrating a fundamental misalignment between text and visual feature spaces. They propose an online pseudo-supervised framework that learns visual prototypes directly from unlabeled test data, achieving state-of-the-art OOD detection performance.

Enhancing Visual Representation with Textual Semantics: Textual Semantics-Powered Prototypes for Heterogeneous Federated Learning

Researchers propose FedTSP, a federated learning method that uses pre-trained language models to generate semantically-enriched prototypes for improving model performance across heterogeneous data. The approach leverages textual descriptions of classes to preserve semantic relationships while mitigating data heterogeneity challenges in federated settings.

FedDAP: Domain-Aware Prototype Learning for Federated Learning under Domain Shift

Researchers introduce FedDAP, a federated learning framework that addresses domain shift challenges by constructing domain-specific global prototypes rather than single aggregated prototypes. The method aligns local features with prototypes from the same domain while encouraging separation from different domains, improving model generalization across heterogeneous client data.
