Federated Learning is a distributed Machine Learning framework aimed at training a global model by sharing edge nodes' locally trained models instead of their datasets. In this chapter, you will: compare and contrast definitions of fairness in a machine learning context, select an appropriate notion of fairness for your task, and mitigate unwanted biases at various points in the modeling pipeline to achieve fairer systems. Then this decision is applied to the whole population which is assumed to follow the same underlying distribution. For example, bias is the b in the following formula: y ′ = b + w 1 x 1 + w 2 x 2 + … w n x n. Not to be confused with bias in ethics and fairness or prediction bias. Fairness and robustness are two important concerns for federated learning systems. But what counts as a good explanation in machine learning? When models don’t perform as intended, people and process are normally to blame. In this work, we identify that robustness to data and model poisoning attacks and fairness, measured as the uniformity of performance across devices, are competing constraints in statistically heterogeneous networks. Fortunately, MARVEL dedicates a specific work package for ethics, where fairness in Machine Learning is only part of it.
