About the Course
The Advanced Course on AI (ACAI) is a specialized course in Artificial Intelligence sponsored by EurAI in odd-numbered years. The theme of the 2021 ACAI School is Human-Centered AI.
The notion of “Human Centric AI” increasingly dominates the public AI debate in Europe. It postulates a “European brand” of AI beneficial to humans on both individual and social level that is characterized by a focus on supporting and empowering humans as well as incorporating “by design” adherence to appropriate ethical standards and values such as privacy protection, autonomy (human in control), and non-discrimination. Stated this way (which is how it mostly appears in the political debate) it may seem more like a broad, vague wish list than a tangible scientific/technological concept. Yet, at a second glance, it turns out that it is closely connected to some of the most fundamental challenges of AI.
Within ACAI 2021, researchers from the HumanE-AI-Net consortium will teach courses related to the state of the art in the above areas focusing not just on narrow AI questions but emphasising issues related to the interface between AI and Human-Computer Interaction (HCI), Computational Social Science (and Complexity Science) as well as ethics and legal issues. We intend to provide the attendees with the basic knowledge needed to design, implement, operate and research the next generation of Human Centric AI systems that are focused on enhancing Human capabilities and optimally cooperating with humans on both the individual and the social level.
ACAI 2021 will have a varied format, including keynote presentations, labs/hands-on sessions, short tutorials on cutting edge topics and longer in-depth tutorials on main topics in AI.

Learning and Reasoning with Human in the Loop
Learning, reasoning, and planning are interactive processes involving close synergistic collaboration between AI system(s) and user(s) within a dynamic, possibly open-ended real-world environment. Key gaps in knowledge and technology that must be addressed toward this vision include combining symbolic-subsymbolic learning, explainability, translating a broad, vague notion of “fairness” into concrete algorithmic representations, continuous and incremental learning, compositionality of models and ways to adequately quantify and communicate model uncertainty.
Human interaction and human collaboration depend on the ability to understand the situation and reliably assign meanings to events and actions. People infer such meanings either directly from subtle cues in behavior, emotions, and nonverbal communications or indirectly from the context and background knowledge. This requires not only the ability to sense subtle behavior, and emotional and social cues but an ability to automatically acquire and apply background knowledge to provide context. The acquisition must be automatic because such background knowledge is far too complex to be hand-coded. Research on artificial systems with such abilities requires a strong foundation for the perception of humans, human actions, and human environments. In HumanE AI Net, we will provide this foundation by building on recent advances in multimodal perception and modelling sensory, spatiotemporal, and conceptual phenomena
Representations and Modeling
Perception is the association of external stimuli to an internal model. Perception and modelling are inseparable. Human ability to correctly perceive and interpret complex situations, even when given limited and/or noisy input, is inherently linked to a deep, differentiated, understanding based on the human experience. A new generation of complex modelling approaches is needed to address this key challenge of Human Centric AI including Hybrid representations that combine symbolic, compositional approaches with statistical and latent representations. Such hybrid representations will allow the benefits of data-driven learning to be combined with knowledge representations that are more compatible with the way humans view and reason about the world around them.
Human Computer Interaction (HCI)
Beyond considering the human in the loop, the goal of human-AI is to study and develop methods for combined human-machine intelligence, where AI and humans work in cooperation and collaboration. This includes principled approaches to support the synergy of human and artificial intelligence, enabling humans to continue doing what they are good at but also be in control when making decisions. It has been proposed that AI research and development should follow three objectives: (i) to technically reflect the depth characterized by human intelligence; (ii) improve human capabilities rather than replace them; and (iii) focus on AI’s impact on humans. There has also been a call for the HCI community to play an increasing role in realizing this vision, by providing their expertise in the following: human-machine integration/teaming, UI modelling and HCI design, transference of psychological theories, enhancement of existing methods, and development of HCI design standards.
As increasingly complex sociotechnical systems emerge, consisting of many (explicitly or implicitly) interacting people and intelligent and autonomous systems, AI acquires an important societal dimension. A key observation is that a crowd of (interacting) intelligent individuals is not necessarily an intelligent crowd. Aggregated network and societal effects and of AI and their (positive or negative) impacts on society are not sufficiently discussed in the public and not sufficiently addressed by AI research, despite the striking importance to understand and predict the aggregated outcomes of sociotechnical AI-based systems and related complex social processes, as well as how to avoid their harmful effects. Such effects are a source of a whole new set of explainability, accountability, and trustworthiness issues, even assuming that we can solve those problems for an individual machine-learning-based AI system.
Societal, Legal and Ethical Impact
Every AI system should operate within an ethical and social framework in understandable, verifiable and justifiable ways. Such systems must in any case operate within the bounds of the rule of law, incorporating fundamental rights protection into the AI infrastructure. Theory and methods are needed for the Responsible Design of AI Systems as well as to evaluate and measure the ‘maturity’ of systems in terms of compliance with legal, ethical and societal principles. This is not merely a matter of articulating legal and ethical requirements but involves robustness, and social and interactivity design. Concerning the ethical and legal design of AI systems, we will clarify the difference between legal and ethical concerns, as well as their interaction and ethical and legal scholars will work side by side to develop both legal protection by design and value-sensitive design approaches.

Mikel Artetxe at Facebook AI Research has been selected as the winner of the EurAI Doctoral Dissertation Award 2021.
In his PhD research, Mikel Artetxe has fundamentally transformed the field of machine translation, by showing that unsupervised machine translation systems can be competitive with traditional, supervised methods. This is a game-changing finding which has already made a huge impact on the field. To solve this challenging problem of unsupervised machine translation, he has first introduced an innovative strategy for aligning word embeddings from different languages, which are then used to induce bilingual dictionaries in a fully automated way. These bilingual dictionaries are subsequently used in combination with monolingual language models, as well as denoising and back translation strategies, to end up with a full machine translation system.
The EurAI Doctoral Dissertation Award will be officially presented at ACAI 2021 on Tuesday, October 12th, at 17.00 (CET). Mikel Artetxe will also give a talk:
Title: Unsupervised machine translation
Abstract: While modern machine translation has relied on large parallel corpora, a recent line of work has managed to train machine translation systems in an unsupervised way, using monolingual corpora alone. Most existing approaches rely on either cross-lingual word embeddings or deep multilingual pre-training for initialization, and further improve this system through iterative back-translation. In this talk, I will give an overview of this area, focusing on our own work on cross-lingual word embedding mappings, and both unsupervised neural and statistical machine translation.
