Query: Mitigate Bias in Face Recognition using Skewness-Aware Reinforcement
  Learning   Racial equality is an important theme of international human rights law, but
it has been largely obscured when the overall face recognition accuracy is
pursued blindly. More facts indicate racial bias indeed degrades the fairness
of recognition system and the error rates on non-Caucasians are usually much
higher than Caucasians. To encourage fairness, we introduce the idea of
adaptive margin to learn balanced performance for different races based on
large margin losses. A reinforcement learning based race balance network
(RL-RBN) is proposed. We formulate the process of finding the optimal margins
for non-Caucasians as a Markov decision process and employ deep Q-learning to
learn policies for an agent to select appropriate margin by approximating the
Q-value function. Guided by the agent, the skewness of feature scatter between
races can be reduced. Besides, we provide two ethnicity aware training
datasets, called BUPT-Globalface and BUPT-Balancedface dataset, which can be
utilized to study racial bias from both data and algorithm aspects. Extensive
experiments on RFW database show that RL-RBN successfully mitigates racial bias
and learns more balanced performance for different races.
