Title: Context Knowledge and Large Language models

Abstract:
In recent years, there has been a rapid advancement in generative AI and its applications, highlighted by the widespread release of ChatGPT on the Web, showcasing both its potential and limitations. Large Language Models are one of the core technologies driving generative AI and are currently being used across a wide range of NLP tasks, including machine translation, conversational agents, and more. However, LLMs still expose certain limitations, notably their inability to fully understand and rely on context knowledge relevant to the specific task.
A typical approach is to make use prompting techniques to guide the generation of text by taking into account the so called “in-context”, without modifying the model’s parameters. Recently, a branch of research is focusing on exploring ways to improve the modeling and control of the process of injecting context (world knowledge) into models. In this talk, I will present some approaches aimed at this goal, and I will discuss the research challenge of creating personal language models—LLMs tailored to a specific user knowledge (such as the user expertise and language knowledge of individual users or specific user groups).

Title: Adversarial robustness certification for neural networks: progress and challenges

Abstract:
Machine learning solutions are revolutionizing AI, but their instability against adversarial examples – small perturbations to inputs that can drastically change the output – raises concerns about the readiness of this technology for widespread deployment. Using illustrative examples, this lecture will give an overview of certification methodologies currently under development, which aim to provide provable guarantees on safety and robustness of neural network decisions. These draw on convex relaxation, uncertainty quantification and Bayesian methods, and include guarantees against adversarial perturbations and patch attacks, as well as quantitative verification, which aims to quantify the proportion of inputs that satisfy an output specification.

Bio
Marta Kwiatkowska is a Professor at the University of Oxford and Polish Academy of Sciences, and Fellow at Trinity College Oxford. Her area of expertise lies in probabilistic and quantitative verification techniques and the synthesis of correct-by-construction systems from quantitative specifications. She led the development of the probabilistic model checker PRISM, winner of the 2024 ETAPS Test-of-Time Tool Award, which has been used to model and verify numerous case studies across a variety of application domains. Recently, she has been focusing on safety and trust in Artificial Intelligence, with an emphasis on robustness guarantees for machine learning. Her research has been supported by two ERC Advanced Grants, VERIWARE and FUN2MODEL, EPSRC Programme Grant on Mobile Autonomy and EPSRC Prosperity Partnership FAIR. Kwiatkowska won the Royal Society Milner Award, the BCS Lovelace Medal and the Van Wijngaarden Award, and received an honorary doctorate from KTH Royal Institute of Technology in Stockholm.

Title: Algorithmic Intelligence: The Programmatic Framework for AI

Abstract:
Programming languages allow expressing algorithms in a manner that feels natural to humans and can be interpreted by machines. However, it was only four decades ago that the notion of programs generating other programs began to be given serious consideration by the scientific community. Since then, the field of program synthesis has evolved and matured considerably, primarily as a theoretical branch of computer science with limited practical implications. Recent advancements in AI and the pursuit of AGI have led to a renewed appreciation of the power and universality of the programmatic perspective. In this talk, I will discuss the role of algorithmic representations and program synthesis in the contemporary AI, exploring how this paradigm is revolutionizing the field, bridging the symbolic and subsymbolic worlds, and what its implications and opportunities are. In particular, I will show how algorithmic intelligence can address the many limitations of mainstream AI, such as its unquenchable thirst for data and lack of transparency, especially in scenarios that require abstract reasoning, structured representations, modularity and compositionality.
