A generalized Catoni's M-estimator under finite α-th moment assumption with α∈(1, 2)

P Chen, X Jin, X Li, L Xu - Electronic Journal of Statistics, 2021 - projecteuclid.org
We generalize Catoni's M-estimator, put forward in [3] by Catoni under finite variance
assumption, to the case in which distributions can have finite α-th moment with α∈(1, 2). Our …

Mitigating label bias in machine learning: Fairness through confident learning

Discrimination can occur when the underlying unbiased labels are overwritten by an agent
with potential bias, resulting in biased datasets that unfairly harm specific groups and cause …
