• Abstract summary: Privacy and fairness are crucial pillars of responsible Artificial Intelligence (AI) and trustworthy Machine Learning (ML) Despite significant interest, there remains an immediate demand for more in-depth research to unravel how these two objectives can be simultaneously integrated into ML models. We provide a thorough review of privacy and fairness in ML, including supervised, unsupervised, semi-supervised, and reinforcement learning.

• Abstract: Privacy and fairness are two crucial pillars of responsible Artificial Intelligence (AI) and trustworthy Machine Learning (ML). Each objective has been independently studied in the literature with the aim of reducing utility loss in achieving them. Despite the significant interest attracted from both academia and industry, there remains an immediate demand for more in-depth research to unravel how these two objectives can be simultaneously integrated into ML models. As opposed to well-accepted trade-offs, i.e., privacy-utility and fairness-utility, the interrelation between privacy and fairness is not well-understood. While some works suggest a trade-off between the two objective functions, there are others that demonstrate the alignment of these functions in certain scenarios. To fill this research gap, we provide a thorough review of privacy and fairness in ML, including supervised, unsupervised, semi-supervised, and reinforcement learning. After examining and consolidating the literature on both objectives, we present a holistic survey on the impact of privacy on fairness, the impact of fairness on privacy, existing architectures, their interaction in application domains, and algorithms that aim to achieve both objectives while minimizing the utility sacrificed. Finally, we identify research challenges in achieving privacy and fairness concurrently in ML, particularly focusing on large language models.

• A Multivocal Literature Review on Privacy and Fairness in Federated Learning [1.6124402884077915]
  Federated learning presents a way to revolutionize AI applications by eliminating the necessity for data sharing. Recent research has demonstrated an inherent tension between privacy and fairness. We argue that the relationship between privacy and fairness has been neglected, posing a critical risk for real-world applications.

  This paper examines the costs associated with achieving privacy and robustness in distributed machine learning architectures. Traditional noise injection hurts accuracy by concealing poisoned inputs, while cryptographic methods clash with poisoning defenses due to their non-linear nature. We outline future research directions aimed at reconciling this compromise with efficiency by considering weaker threat models.

We provide an answer to the question of where fairness mitigation should be integrated within a privacy-aware ML pipeline.

  An exploration-exploitation trade-off is central to the description of adaptive behaviour. One approach to solving this trade-off has been to equip or propose that agents possess an intrinsic 'exploratory drive' We show that this combination of utility maximizing and information-seeking behaviour arises from the minimization of an entirely difference class of objectives.
