What are the limlitations of federated learning in tterm of privacy ?5 answersFederated Learning (FL) has limitations in terms of privacy. Existing FL methods require synchronized communication and suffer from privacy leakage risk. Privacy concerns restrict access to medical data, preventing the full exploitation of deep learning techniques in healthcare. Personalized FL addresses the issue of non-identically independently distributed data but raises privacy concerns due to the exchange of patient-level information. To address this, Privacy-preserving Community-Based Federated machine Learning (PCBFL) uses Secure Multiparty Computation to securely calculate patient-level similarity scores across hospitals. Additionally, the need for uncertainty quantification and data privacy constraints in FL is addressed by training customized local Bayesian models that provide characterizations of model uncertainties. To ensure privacy in personalized graph federated learning, a variant of the PGFL implementation utilizes differential privacy, specifically zero-concentrated differential privacy.
WHAT IS federated learning ?4 answersFederated Learning (FL) is a machine learning paradigm that enables clients to jointly train a global model by aggregating the locally trained models without sharing any local training data. FL addresses the challenges of training models in a distributed environment with heterogeneous data distributions across clients. It suffers from the 'client-drift' problem where every client converges to its own local optimum, resulting in slower convergence and poor performance of the aggregated model. To overcome this limitation, regularization techniques based on adaptive self-distillation (ASD) have been proposed. These techniques adaptively adjust to the client's training data based on the closeness of the local model's predictions with that of the global model and the client's label distribution. The proposed regularization can be integrated with existing FL algorithms, leading to improved performance.
Whatś the state of art of federated learning?5 answersFederated learning (FL) is a new and promising paradigm that allows devices to learn without sharing data with the centralized server. FL models based on game theory (GT) have been developed to maximize profit, ensure authentication, privacy management, trust management, and threat detection. However, the inherent characteristics of federated learning pose security concerns, such as backdoor attacks. These attacks can introduce backdoored functionality into the global model, leading to misclassification of malicious images. To address this, defenses including anomaly updates detection, robust federated training, and backdoored model restoration have been proposed. Additionally, the heterogeneity of data distributions, model architectures, network environments, and hardware devices among participant clients in practical federated learning has led to the development of Heterogeneous Federated Learning (HFL) methods.

How has Luhmann's work on "functional differentiation" influenced the study of polarization in modern societies?
5 answers
Niklas Luhmann's theory of "functional differentiation" has significantly influenced the study of polarization in modern societies by providing a theoretical framework that explains the complexity and dynamics of societal structures and their evolution. Luhmann's work suggests that modern societies are characterized by a high degree of differentiation, where various subsystems (such as politics, law, and economy) operate autonomously based on their own codes and logics. This differentiation is essential for the complexity and adaptability of society, but it also introduces challenges in terms of integration and coherence across different societal domains. Luhmann's skepticism towards the role of morality in modern society, as discussed by Vladislav Valentinov, indirectly touches upon the roots of polarization, highlighting the tension between the expansion of political systems and the sustainability of social systems within their societal and natural environments. This tension can exacerbate polarization as different subsystems pursue their objectives, often at the expense of overarching societal cohesion. The application of Luhmann's theory to historical studies, as demonstrated by Kosuke Sakai, provides methodological insights into understanding the evolution of societal structures, including the conditions that foster polarization. By examining the semantic variations connected to institutional formations, researchers can trace how differentiation processes contribute to or mitigate polarization within society. Furthermore, Luhmann's insights into the function of education and its relation to modern society underscore the role of socialization processes in either reinforcing or challenging polarized perspectives, thereby influencing the degree of societal cohesion or division. The concept of legal autonomy and the differentiation of the political system into sub-systems, as explored by Theodore Shulman, offer a nuanced understanding of how judicial politicization and constitutional adjudication can reflect and influence societal polarization. G. R. Shakhmametova's methodology for quantifying polarization through the Turing instability mechanism aligns with Luhmann's systemic approach by providing a tool to measure differentiation and polarization within networks, thereby offering empirical evidence of Luhmann's theoretical propositions. In summary, Luhmann's work on "functional differentiation" has profoundly influenced the study of polarization in modern societies by offering a comprehensive theoretical framework that helps explain the emergence, dynamics, and consequences of societal divisions. This framework has been applied and extended in various empirical and methodological studies, enriching our understanding of the complex interplay between societal differentiation and polarization.
