Using AI bias for good: poverty and inequality mitigation
Abstract: The talk is framed in the AI for Good interdisciplinary area of work, which seeks to direct AI research towards the advancement of the United Nations Sustainable Development Goals. In particular, I will be presenting lines of research in AI-enabled tools that aim to open new paths for poverty reduction by acting on social discrimination. While bias mitigation in AI has generated an important body of publications, we argue that online bias can be useful to identify and measure shared beliefs that influence social policy making. In this talk, I will outline research directions that aim to generate a global index on discrimination against the poor (through NLP and LLMs), and to optimize poverty-mitigation policies via AI simulations (Agent-Based Modeling).

The search for personality markers in text: Challenges for contemporary psychological science
Abstract: The lecture will introduce the field of psychology of language and word use, both in terms of its goals, methods, and results. The primary focus will be on the method of computational psychological-linguistic text analysis, which has dominated the field for the last three decades. Attention will be paid to the elaboration of main psycho-linguistic projects, which examined relations between the use of linguistic categories in written/oral texts and personality characteristics of the author. Different levels of the text will be discussed, especially linguistic morphology, syntax and stylistics. We focus on comparison of the studies, summarize available results, provides their interpretations in a cross-linguistic and cross-situational perspective. We conclude the lecture by presenting key challenges for contemporary (not only) psychological science.

Exploring NLP Advancements: Addressing Biases and Human Values in Large Language Models
Abstract: This talk will introduce the Natural Language and Text Processing Lab (NLTP) at Utrecht University (https://nlp.sites.uu.nl/), highlighting its focus on applications of NLP and large language models. The lab conducts cutting-edge research, exploring various domains where NLP can be transformative. An overview of selected ongoing projects will be given, showing how advanced NLP techniques are used to solve real-world problems. The second part of the talk will focus on a recent study investigating the sensitivity of large language models to human values and biases. These models often reflect societal and cultural biases present in their training data. While previous research has shown that monolingual models can exhibit moral biases, there is a gap in understanding how these biases manifest in different cultural contexts. This study investigates the extent to which monolingual and multilingual models encode knowledge of moral norms from different countries. Explainable NLP tools are used to interpret the inferences made by these models, providing insights into how they incorporate and reflect moral variation across cultures.

Towards vision based Emotion AI
Abstract: Emotions play a key role in human-human interactions and become one key focus in future Artificial Intelligence. There is a growing need to develop emotionally intelligent interfaces, which are able to read the emotions of the users and adapt their operations accordingly. Among the areas of application are human-robot interaction, emotional chatpots, health and medicine, on-line learning, user or customer analysis, and security and safety. This talk will provide an introduction to the emotional interfaces, and overviews our progress in related research. The research topics to be covered include facial (micro)-expression recognition, emotional gestures, remote heart rate measurement from videos and potential applications. Finally, some future challenges are outlined.

Towards Unbiased LLMs from the Roots: Exploring Biases in Language Corpora
Abstract: In the rapidly advancing field of Natural Language Processing (NLP), driven by the widespread adoption of Large Language Models (LLMs), biases inherent in these models mirror the broader societal biases present in the textual data they are trained on. One of the typical examples is the gender bias. For instance, LLMs inadvertently perpetuate stereotypes by linking certain professions or characteristics more strongly with a particular gender. This talk will examine the entire pipeline associated with biases in textual data sets (language corpora). We will discuss the most prevalent types of biases, investigate the methods to measure them and suggest techniques for debiasing the data. The talk will present relevant related work and provide useful insights into practical strategies for identifying and mitigating biases in textual data.

Fast approximate matrix multiplication – theory and practice in AI hardware
Abstract: Multiplying large, dense matrices is a key ingredient of deep networks, and state of the art architectures may spend more than 99% of time and energy consumption on matrix multiplication. Although fast matrix multiplication algorithms in time o(n^3) are known in the theoretical literature, they are impractical, and not used in the AI hardware and software ecosystem today. In this talk I will survey algorithms and heuristics for faster approximate matrix multiplication, and show the possible impact, as well as limitations, of such approaches on the future of deep learning. The results I will present will cover both academic research, as well as my more recent experience with cutting edge AI industry at deci.ai, where I have discovered a huge gap between the academic research and practical AI.
