In this paper, we study the decentralized federated learning problem, which involves the collaborative training of a global model among multiple devices while ensuring data *** classical federated learning, the communication channel between the devices poses a potential risk of compromising private information. To reduce the risk of adversary eavesdropping in the communication channel, we propose TRADE(transmit difference weight) concept. This concept replaces the decentralized federated learning algorithm's transmitted weight parameters with differential weight parameters, enhancing the privacy data against eavesdropping. Subsequently, by integrating the TRADE concept with the primal-dual stochastic gradient descent(SGD)algorithm, we propose a decentralized TRADE primal-dual SGD algorithm. We demonstrate that our proposed algorithm's convergence properties are the same as those of the primal-dual SGD algorithm while providing enhanced privacy protection. We validate the algorithm's performance on fault diagnosis task using the Case Western Reserve University dataset, and image classification tasks using the CIFAR-10 and CIFAR-100 datasets,revealing model accuracy comparable to centralized federated learning. Additionally, the experiments confirm the algorithm's privacy protection capability.

Traditional research on skin diseases has mainly focused on biological characteristics for a long time. Recently, the integration of biomechanics and mechanobiology has introduced mechanical factors into skin disease research. The interaction between mechanical factors and skin's physiological and pathological changes has gradually been transformed in clinical diagnosis and treatment. The two emerging fields, mechanodiagnostics and mechanotherapy, have been developed to address clinical needs. However, clinicians often lack a comprehensive understanding of skin mechanical characteristics and the mechanobiological mechanisms in dermatology. Thus, we propose the concept of "skin mechanomedicine". By summarizing relevant research at home and abroad, this paper systematically elucidates the multiscale mechanical characteristics of skin diseases and their impact on biological behavior from four perspectives: skin biomechanics, skin mechanobiology, skin mechanodiagnostics, and skin mechanotherapy. Meanwhile, in-depth exploration was conducted on the potential application of mechanical factors in the diagnosis and treatment of skin diseases, aiming to provide new research perspectives and solutions for the diagnosis and treatment of skin diseases.
