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: 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.
