DOI: 10.1109/tnnls.2021.3105810
Abstract: Due to the distributed characteristics of federated learning (FL), the vulnerability of the global model and the coordination of devices are the main obstacle. As a promising solution of decentralization, scalability, and security, leveraging the… read more here.

DOI: 10.3760/cma.j.cn112338-20220906-00765
Abstract: Measurement bias (MB) has been described in causal structures but is still not entirely clear. In practice, the correctness of substitution estimate (SE) of effect is a prerequisite for causal inference, usually based on a… read more here.
