• Abstract: Blockchain-enabled Federated Learning (BFL) enables mobile devices to collaboratively train neural network models required by a Machine Learning Model Owner (MLMO) while keeping data on the mobile devices. Then, the model updates are stored in the blockchain in a decentralized and reliable manner. However, the issue of BFL is that the mobile devices have energy and CPU constraints that may reduce the system lifetime and training efficiency. The other issue is that the training latency may increase due to the blockchain mining process. To address these issues, the MLMO needs to (i) decide how much data and energy that the mobile devices use for the training and (ii) determine the block generation rate to minimize the system latency, energy consumption, and incentive cost while achieving the target accuracy for the model. Under the uncertainty of the BFL environment, it is challenging for the MLMO to determine the optimal decisions. We propose to use the Deep Reinforcement Learning (DRL) to derive the optimal decisions for the MLMO.

  We employ Federated Learning (FL) and prominent features of blockchain into Mobile Edge Computing architecture. FL is advantageous for mobile devices with constrained connectivity since it requires model updates to be delivered to a central point. We propose a fully asynchronoused Federated Learning framework referred to as BFL-MEC, in which the mobile clients evolve independently yet guarantee stability in the global learning process.

• How Much Does It Cost to Train a Machine Learning Model over Distributed Data Sources? [4.222078489059043]
  Federated learning allows devices to train a machine learning model without sharing their raw data. Server-less FL approaches like gossip federated learning (GFL) and blockchain-enabled federated learning (BFL) have been proposed to mitigate these issues. GFL is able to save the 18% of training time, the 68% of energy and the 51% of data to be shared with respect to the CFL solution, but it is not able to reach the level of accuracy of CFL. BFL represents a viable solution for implementing decentralized learning with a higher level of security, at the cost of an extra energy usage and data sharing

We explore the impact of lazy clients on the learning performance of BLADE-FL, and characterize the relationship among the optimal K, the learning parameters, and the proportion of lazy clients.

  Internet of Things (IoT) devices may not be able to transmit their collected data to a central controller for training machine learning models.
