Raffaella Bernardi: An old Artificial Intelligence dream that comes true: Merging language and vision modalities

September 10, 2018. Tid: 15:15 - 16:30

Abstract In the last decade, there has been an explosion of papers on the combination of the language and vision modalities.  In this tutorial, we will first aim to understand why this is happening, what has made the investigation possible, and where do we stand now. We will see that research has been mostly been driven by applications, but that behind this work there are quite interesting foundational questions. We will conclude the tutorial by zooming into the issue of grounding…

Pekka Parviainen: Introduction to Bayesian networks – the backbone of probabilistic modelling

Abstract In this talk, Parviainen will give an overview of Bayesian networks: what are they, what can be done with them and where do they come from? They were invented in the 1980s, mainly as a result of research by Judea Pearl. Bayesian networks are probabilistic graphical models that represent relations between random variables. They enable efficient probabilistic inference and causal analysis and are found  “under the hood” in many probabilistic models. They have been significant in reasoning with uncertainty…

Enrico Motta: Hybrid AI: Integrating large scale data analysis with semantic technologies

Abstract Over the past 10-15 years we have witnessed a paradigm shift in computer science, brought about by the availability of large scale amounts of data. As a result of this paradigm shift new opportunities have arisen, allowing us to study the dynamics of a variety of phenomena, such as social networks, people’s mobility, shopping behaviours, etc. To this purpose new machine learning and data mining solutions have been devised, which are able to effectively identify patterns in the data…

Abstract Recommender systems is an applied AI technique that we often meet when surfing the web. In many applications of such systems, a larger fraction of the user population are first-time users or are not logged in when they use the service. In these cases, the item suggestions by the recommender cannot be based on individual long-term preference profiles. Instead, the recommendations have to be determined based on the observed short-term behavior of the users. Due to the high practical…

Pablo Gervás Gómes-Navarro: Modelling How People Build Stories from Observed Facts

February 13, 2019. Tid: 14:15 - 15:30

Notice: This particular AI Agora event will NOT be taking place at Media City Bergen. This time, the venue for the event is the Social Science Building, Fosswinckelsgt. 6. Please see details below. Abstract People communicate most often by telling stories based on their experience of reality. In this process, three fundamental ingredients need to be combined: the observed facts as perceived from reality, the knowledge of narrative structure that is shared between the teller and the listener, and the…

Marija Slavkovik: The Jiminy Advisor: Moral Agreements Among Stakeholders Based on Norms and Argumentation

Abstract This lecture introduces the problem of engineering machine ethics and ethical governors in general, and focuses on a recent contribution to this area: the problem of who decides what is right or wrong for a machine. An autonomous system is constructed by a manufacturer, operates in a society subject to norms and laws, and is interacting with end-users. All of these actors are stakeholders affected by the behaviour of the autonomous system. We address the challenge of how the…

Ana Ozaki: Knowledge Graphs: Facts and Figures

Abstract In this talk, Ana Ozaki will give an introduction to knowledge graphs, starting with the basics: What are knowledge graphs, how are they created, and what are they used for? Then, Ozaki will focus on special cases; in particular, the knowledge graphs of the Wikidata, DBpedia, and YAGO projects. Ozaki will discuss the main reasoning tasks and how to enhance reasoning using common types of meta-knowledge present in knowledge graphs; in particular,  temporal validity and provenance. Then she will…

Abstract Discussions surrounding questions of interpretability (or even: explainability) in AI and ML are gaining in popularity in academia and industry. I will briefly characterize four notions of explainable AI/ML that cut across research fields: 1) opaque systems that offer no insight whatsoever, 2) interpretable systems where users can mathematically analyse the mechanisms at work, 3) comprehensible systems that emit symbols enabling user-driven explanations of how a conclusion is reached,  and 4) explainable systems, where automated reasoning is central to…

Khanh-Duy Le: From Eyes to Hands: Leveraging Non-verbal Cues to Connect People Remotely

Abstract In our everyday communication, besides speech, non-verbal cues such as gaze and hand gestures (looking directions) play a crucial role in allowing us to communicate and work together efficiently. However, current remote collaboration solutions, such as video conferencing interfaces, do not support these cues effectively. This is due to certain hardware limitations of commodity personal computers, such as laptop or tablet, reducing users’ communication and performance in several contexts. In this talk, we will first go through different research…
