The 4th edition of the Montreal AI Ethics Institute's The State of AI Ethics captures the most relevant developments in the field of AI Ethics since January 2021. This report aims to help anyone, from machine learning experts to human rights activists and policymakers, quickly digest and understand the ever-changing developments in the field. Through research and article summaries, as well as expert commentary, this report distills the research and reporting surrounding various domains related to the ethics of AI, with a particular focus on four key themes: Ethical AI, Fairness & Justice, Humans & Tech, and Privacy. In addition, The State of AI Ethics includes exclusive content written by world-class AI Ethics experts from universities, research institutes, consulting firms, and governments. Opening the report is a long-form piece by Edward Higgs (Professor of History, University of Essex) titled "AI and the Face: A Historian's View." In it, Higgs examines the unscientific history of facial analysis and how AI might be repeating some of those mistakes at scale. The report also features chapter introductions by Alexa Hagerty (Anthropologist, University of Cambridge), Marianna Ganapini (Faculty Director, Montreal AI Ethics Institute), Deborah G. Johnson (Emeritus Professor, Engineering and Society, University of Virginia), and Soraj Hongladarom (Professor of Philosophy and Director, Center for Science, Technology and Society, Chulalongkorn University in Bangkok). This report should be used not only as a point of reference and insight on the latest thinking in the field of AI Ethics, but should also be used as a tool for introspection as we aim to foster a more nuanced conversation regarding the impacts of AI on the world.

The European Union is the first major power to sound the regulatory klaxon in an attempt to govern the explosion in artificial intelligence-based technology. While some may see this as a threat to a potentially transformative area of innovation, such intervention is timely before it becomes impossible to cage the AI "beast'. In proposals published in April, the EU outlined that it would ban "unacceptable" uses of AI, which it defines as "AI systems considered a clear threat to the safety, livelihoods and rights of people." And, while the EU has taken the lead, it will not be long before others follow. Indeed, beyond AI, there is a general trend toward closer scrutiny of the technology sector with President Joe Biden installing two advocates for regulation within his administration--Lina Khan, just approved by a Senate panel to be an FTC commissioner, and Tim Wu, on the National Economic Council--and the U.K. planning to introduce a new code of practice for technology companies in a bid to curb the domination of tech giants.

European Union (EU) lawmakers have introduced new rules that will shape how companies use artificial intelligence (AI). The rules are the first of their kind to introduce regulation to the sector, and the EU's approach is unique in the world. In the US, tech firms are largely left to themselves, while in China, AI innovation is often government-led and used regularly to monitor citizens without too much hindrance from regulators. The EU bloc, however, is taking an approach that aims to maximise the potential of AI while maintaining privacy laws. There are new regulations around cases that are perceived as endangering people's safety or fundamental rights, such as AI-enabled behaviour manipulation techniques.

Nobel Prize-winning author Kazuo Ishiguro's latest novel Klara and the Sun, his first since receiving the award in literature in 2017, has some relevance for policymakers and ordinary citizens across the globe. The main protagonist in this dystopian science fiction story is Klara, an artificial friend (AF)--a human-like teenager who behaves and thinks almost like her cohort of the same age and is a fast learner, as any device or robot using artificial intelligence (AI) can be expected to be. However, what we also learn is that if robots, even if they are super-intelligent, are allowed to make decisions that affect the lives of humans, it might lead to unintended consequences unless there are strict guidelines protecting privacy and other individual rights. Many discerning readers might already be aware that AI is whipping up quite a storm, particularly as it makes inroads into facial recognition software, law enforcement, and hiring decisions in the corporate world. Policymakers in many countries are alarmed, realising the pros as well as the cons of this revolutionary technology.

The planet is faced with overwhelming environmental problems. Rising environmental pollution is wreaking havoc on nature and endangering the lives of millions of humans. Evolving digital technologies offer a bottom-up solution to tackling climate change. These digital technologies have a revolutionary way to involve citizens in addressing local and global issues. Young people are generally the most worried regarding the consequences of climate change. Early findings of ongoing projects suggest a high potential for leveraging digital technology in joint measures to preserve the world for ourselves and future generations.

The 3rd edition of the Montreal AI Ethics Institute's The State of AI Ethics captures the most relevant developments in AI Ethics since October 2020. It aims to help anyone, from machine learning experts to human rights activists and policymakers, quickly digest and understand the field's ever-changing developments. Through research and article summaries, as well as expert commentary, this report distills the research and reporting surrounding various domains related to the ethics of AI, including: algorithmic injustice, discrimination, ethical AI, labor impacts, misinformation, privacy, risk and security, social media, and more. In addition, The State of AI Ethics includes exclusive content written by world-class AI Ethics experts from universities, research institutes, consulting firms, and governments. Unique to this report is "The Abuse and Misogynoir Playbook," written by Dr. Katlyn Tuner (Research Scientist, Space Enabled Research Group, MIT), Dr. Danielle Wood (Assistant Professor, Program in Media Arts and Sciences; Assistant Professor, Aeronautics and Astronautics; Lead, Space Enabled Research Group, MIT) and Dr. Catherine D'Ignazio (Assistant Professor, Urban Science and Planning; Director, Data + Feminism Lab, MIT). The piece (and accompanying infographic), is a deep-dive into the historical and systematic silencing, erasure, and revision of Black women's contributions to knowledge and scholarship in the United Stations, and globally. Exposing and countering this Playbook has become increasingly important following the firing of AI Ethics expert Dr. Timnit Gebru (and several of her supporters) at Google. This report should be used not only as a point of reference and insight on the latest thinking in the field of AI Ethics, but should also be used as a tool for introspection as we aim to foster a more nuanced conversation regarding the impacts of AI on the world.

In many applications, researchers are interested in the direct and indirect causal effects of an intervention on an outcome of interest. Mediation analysis offers a rigorous framework for the identification and estimation of such causal quantities. In the case of binary treatment, efficient estimators for the direct and indirect effects are derived by Tchetgen Tchetgen and Shpitser (2012). These estimators are based on influence functions and possess desirable multiple robustness properties. However, they are not readily applicable when treatments are continuous, which is the case in several settings, such as drug dosage in medical applications. In this work, we extend the influence function-based estimator of Tchetgen Tchetgen and Shpitser (2012) to deal with continuous treatments by utilizing a kernel smoothing approach. We first demonstrate that our proposed estimator preserves the multiple robustness property of the estimator in Tchetgen Tchetgen and Shpitser (2012). Then we show that under certain mild regularity conditions, our estimator is asymptotically normal. Our estimation scheme allows for high-dimensional nuisance parameters that can be estimated at slower rates than the target parameter. Additionally, we utilize cross-fitting, which allows for weaker smoothness requirements for the nuisance functions.

Machine-generated artworks are now part of the contemporary art scene: they are attracting significant investments and they are presented in exhibitions together with those created by human artists. These artworks are mainly based on generative deep learning techniques. Also given their success, several legal problems arise when working with these techniques. In this article we consider a set of key questions in the area of generative deep learning for the arts. Is it possible to use copyrighted works as training set for generative models? How do we legally store their copies in order to perform the training process? And then, who (if someone) will own the copyright on the generated data? We try to answer these questions considering the law in force in both US and EU and the future alternatives, trying to define a set of guidelines for artists and developers working on deep learning generated art.

Two years ago reports revealed that Amazon was providing facial recognition software for use by police departments, even as questions arose about the bias, privacy and potentially life-destroying errors that could result. A year ago Amazon announced a one year moratorium on such use of its Rekognition platform, and now Reuters reports that instead of letting the ban expire, Amazon has extended it "until further notice." In a statement, ACLU deputy director Nathan Wessler said "Face recognition technology fuels the over-policing of Black and Brown communities, and has already led to the false arrests and wrongful incarcerations of multiple Black men. We are glad that Amazon will extend its moratorium on law enforcement use of the company's face recognition technology. Now, the Biden administration and legislatures across the country must further protect communities from the dangers of this technology by ending its use by law enforcement entirely, regardless which company is selling it."
