About the position

Explainable AI and the EXAIGON project:

The recent rapid advances of Artificial Intelligence (AI) hold promise for multiple benefits to society in the near future. AI systems are becoming ubiquitous and disruptive to industries such as healthcare, transportation, manufacturing, robotics, retail, banking, and energy. According to a recent European study, AI could contribute up to EUR 13.3 trillion to the global economy by 2030; EUR 5.6 trillion from increased productivity and EUR 7.73 trillion from opportunities related to consumer experience. However, in order to make AI systems deployable in social environments, industry and business-critical applications, several challenges related to their trustworthiness must be addressed first. 

Most of the recent AI breakthroughs can be attributed to the subfield of Deep Learning (DL), based on Deep Neural Networks (DNNs), which has been fueled by the availability of high computing power and large datasets. Deep learning has received tremendous attention due to its state-of-the-art, or even superhuman, performance in tasks where humans were considered far superior to machines, including computer vision, natural language processing, and so on. Since 2013, Deep Mind has combined the power of DL with Reinforcement Learning (RL) to develop algorithms capable of learning how to play Atari games from pixels, beating human champions at the game of Go, surpassing all previous approaches in chess, and learning how to accomplish complex robotic tasks. Similarly, DL technology has been used in combination with Bayesian Networks (BNs), resulting in Deep Bayesian Networks (DBNs), a framework that dramatically increases the usefulness of probabilistic machine learning. Despite their impressive performance, DL models have drawbacks, with some of the most important being lack of transparency and interpretability, lack of robustness, and inability to generalize to situations beyond their past experiences. These are difficult to tackle due to the black-box nature of DNNs, which often end up having millions of parameters, hence making the reasoning behind their predictions incomprehensible even to human experts. In addition, there is a need to better understand societal expectations and what elements are needed to ensure societal acceptance of these technologies.

Explainable AI (XAI) aims at remedying these problems by developing methods for understanding how black-box models make their predictions and what are their limitations. The call for such solutions comes from the research community, the industry and high-level policy makers, who are concerned about the impact of deploying AI systems to the real world in terms of efficiency, safety, and respect for human rights. In order for XAI to be useful in business-critical environments and applications, it should not be limited to algorithm design because the experts who understand decision-making models the best are not in the right position to judge the usefulness and structure of explanations. It is necessary to enhance XAI research by incorporating models of how people understand explanations, and when explanations are sufficient for trusting something or someone. Such models have been researched for many years by philosophers, social and cognitive psychologists, and cognitive scientists. It becomes evident that significant interdisciplinary contributions are needed for AI systems to be considered trustworthy enough for deployment in social environments and business-critical applications.

The EXAIGON (Explainable AI systems for gradual industry adoption) project (2020-2024) will deliver research and competence building on XAI, including algorithm design and human-machine co-behaviour, to meet the society’s and industry’s standards for deployment of trustworthy AI systems in social environments and business-critical applications. Extracting explanations from black-box models will enable model verification, model improvement, learning from the model, and compliance to legislation. 
EXAIGON aims at creating an XAI ecosystem around the Norwegian Open AI-Lab (NAIL), including researchers with diverse background and strong links to the industry. The project is supported by 7 key industry players in Norway who will provide the researchers with use cases, including data, models and expert knowledge. EXAIGON is a collaborative research effort by the Departments of Computer Science and Engineering Cybernetic around the Norwegian Open AI-lab. All involved researchers will work closely with each other, the industry partners, and researchers already working on relevant topics at NTNU, hence maximizing the project’s impact and relevance to the real world.

For all their merits and compelling results, the uptake of AI methods till date into actual, consequential decision-making in organisations have been uneven. The theme of the postdoc is to analyse technical, social, organisational and institutional conditions that enable and hamper uptake of AI methods in general and XAI ones in particular. An understanding of such conditions is fed back into the ongoing development of improved methods and techniques for XAI by other EXAIGON research partners.

The EXAIGON research partners will explore techniques from reinforcement learning, supervised learning and Bayesian networks to enhance the transparency and thus, potentially, the explainability of decision support. The focal theme of the postdoc is to analyse how these different methods are perceived, understood and used by different users in the partner companies of EXAIGON to evaluate their relative merit. In other words, the postdoc will require a deep analytic and empirical understanding of the organizational context together with knowledge and interest into the details of different AI methods.
The postdoc position will rely predominately on qualitative or interpretative research methods as empirical data will comprise observations, interviews and trace data of users.
The postdoc will have the option for a research stay abroad during their studies. Potential destinations are the USA and Australia, where EXAIGON has established scientific collaborators.

The project is funded by the Research Council of Norway (RNC). 

You will report to IDI, head of the department.
