CorrFL: Correlation-Based Neural Network Architecture for Unavailability Concerns in a Heterogeneous IoT Environment
نویسندگان
چکیده
The Federated Learning (FL) paradigm faces several challenges that limit its application in real-world environments. These include the local models' architecture heterogeneity and unavailability of distributed Internet Things (IoT) nodes due to connectivity problems. factors posit question "how can available models fill training gap unavailable models?". This is referred as "Oblique Learning" problem. problem encountered studied environment includes IoT responsible for predicting CO2 concentrations. paper proposes Correlation-based FL (CorrFL) approach influenced by representational learning field address this CorrFL projects various model weights a common latent space heterogeneity. Its loss function minimizes reconstruction when are absent maximizes correlation between generated models. latter factor critical because intersection feature spaces devices. evaluated on realistic use case, involving one device heightened activity levels reflect occupancy. from ones trained new compared against different cases, benchmark model. evaluation criteria combine mean absolute error (MAE) predictions impact amount exchanged data prediction performance improvement. Through comprehensive experimental procedure, outperformed every criterion.

متن کاملA conjugate gradient based method for Decision Neural Network training
Decision Neural Network is a new approach for solving multi-objective decision-making problems based on artificial neural networks. Using inaccurate evaluation data, network training has improved and the number of educational data sets has decreased. The available training method is based on the gradient decent method (BP). One of its limitations is related to its convergence speed. Therefore,...
متن کاملNew Security Architecture for IoT Network
We explain the notion of security architecture for Internet of Things (IoT) based on software-defined networking (SDN). In this context, the SDN-based architecture works with or without infrastructure, that we call SDN-Domain. This work describes the operation of the proposed architecture and summarizes the opportunity to achieve network security in a more efficient and flexible with SDN. An ov...
