Data sharing and collaborative model training are promising ways to improve the quality of deep-learning models. However, it is usually difficult to implement such settings in practice due to data privacy concerns and relative regulations such as the GDPR and HIPAA. Federated learning aims to train collaboratively on distributed data sources without disclosing private data from each of the data sources, thus enabling privacy-preserving data sharing and collaboration.
However, federated learning also faces multiple challenges that may limit its applications in real-world use scenarios. For example, federated learning is still under the risk of various kinds of attacks that may result in leakage of individual data source privacy or degraded joint model accuracy. On the other hand, the common federated settings can only protect data privacy for each participant, but cannot identify incorrect inputs and computations from malicious participants. Thus, techniques like verifiable computing are also needed in federated learning. Furthermore, data privacy is a concern in critical businesses like the financial and healthcare industry, but the model interpretability is also essential. For a model generated from federated training, the model behavior or results need to be explainable and auditable to be widely used with confidence. It eventually leads to implementations of federated learning providers that will gain the trust of the federated learning consumers/users.
Federated learning on non-IID distributed data sources usually leads to lower model performance. Designing proper incentive mechanisms for federated systems is beneficial in practice as it encourages the active participation of data owners. Social responsibility in federated-learning systems is also an important topic that needs to be addressed.
