Practical Insights on Incremental Learning of New Human Physical Activity on the Edge

no code implementations22 Aug 2023 George Arvanitakis, Jingwei Zuo, Mthandazo Ndhlovu, Hakim Hacid

Edge Machine Learning (Edge ML), which shifts computational intelligence from cloud-based systems to edge devices, is attracting significant interest due to its evident benefits including reduced latency, enhanced data privacy, and decreased connectivity reliance.

The Price of Local Fairness in Multistage Selection

1 code implementation15 Jun 2019 Vitalii Emelianov, George Arvanitakis, Nicolas Gast, Krishna Gummadi, Patrick Loiseau

In particular, our experiments show that the price of local fairness is generally smaller when the sensitive attribute is observed at the first stage; but globally fair selections are more locally fair when the sensitive attribute is observed at the second stage---hence in both cases it is often possible to have a selection that has a small price of local fairness and is close to locally fair.
