Special Issue Information

Dear Colleagues,

In the big data era, parallel computing is the most efficient way to solve large-size problems. By utilizing the parallel design of recent architectures, very sophisticated parallelization strategies can be realized and implemented in order to provide efficient parallel software.

This Special Issue aims to collect papers that present new parallel methods and algorithms for solving large-scale dimension problems for multi/many core, GPU and distributed architectures.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs).

In federated learning (FL), clients train models locally without sharing raw data, ensuring data privacy. In particular, federated distillation transfers knowledge to clients regardless of the model architecture. However, when groups of clients with different label distributions exist, sharing the same knowledge among all clients becomes impractical. To address this issue, this paper presents an approach that clusters clients based on the output of a client model trained using their own data. The clients are clustered based on the predictions of their models for each label on a public dataset. Evaluations on MNIST and CIFAR show that our method effectively finds group identities, increasing accuracy by up to 75% over existing methods when the distribution of labels differs significantly between groups. In addition, we observed significant performance improvements on smaller client groups, bringing us closer to fair FL. Full article
