It aims to develop a global model in a distributed manner that generalizes to unseen clients. However, it faces the challenge of the tradeoff between inter-client and intra-client domain shifts. Knowledge distillation from the vision-language model may address this challenge by transferring its zero-shot generalization ability to client models. However, it may suffer from distribution discrepancies between the pretraining data of the vision-language model and the downstream data. Although pre-distillation fine-tuning may alleviate this issue in centralized settings, it may not be compatible with FedDG. In this paper, we introduce an in-distillation selective adaptation framework for FedDG. It selectively fine-tunes unreliable outputs while directly distilling reliable ones from the vision-language model, effectively using knowledge distillation to address the challenge in FedDG. Furthermore, we propose a federated energy-driven reliability appraisal (FedReap) method to support this framework by appraising the reliability of outputs from the vision-language model. It includes hypersphere-constraint energy construction and label-guided energy partition. These two processes enable FedReap to acquire reliable and unreliable outputs for direct distillation and adaptation. In addition, FedReap employs a dual-level distillation strategy and a dual-stage adaptation strategy for distillation and adaptation. Extensive experiments on five datasets demonstrate the effectiveness of FedReap compared to twelve state-of-the-art methods.</div></div>","PeriodicalId":50367,"journal":{"name":"Information Fusion","volume":"127 ","pages":"Article 103714"},"PeriodicalIF":15.5,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a novel cross-modality semi-supervised transfer learning from MRI to US by leveraging annotated data in the MRI modality. A diffusion model, leveraging conditional texture features and guided mutual information, transforms well-annotated MRI images into synthetic US images with a distribution closer to real US images. Subsequently, we employ a segmentation framework that involves pretraining with synthetic US images derived from MRI through image translation, followed by semi-supervised fine-tuning using a hybrid dataset that integrates both labeled and unlabeled ultrasound data. Extensive assessments are reported on the utility of SL-DDPM against competing GAN and diffusion models in MRI-US translation. The experimental results demonstrate that our proposed transfer learning strategy achieves a segmentation accuracy of DSC of 93.43 ± 3.72 %. The effectiveness of our strategy is validated through ablation studies on fine-tuning strategies and semi-supervised learning, as well as comparisons with other state-of-the-art methods.

A set of random variables is introduced to indicate which combination of state prediction components is selected for transmission at each time step. In the case that the sensor node does not know which combination of state prediction components from each neighboring node is transmitted to it at each time step, a distributed Kalman-like recursive estimator structure that depends on the probability distributions of random variables is developed.
