9:00-9:45 | The Shortest History of AI Since Alan Turing first posed the question, ‘Can machines think?’, artificial intelligence has evolved from a speculative idea to a transformative force. I trace this evolution, from Ada Lovelace's visionary work to defeating chess and Go world champions and the emergence of ChatGPT. I argue that many ‘overnight’ successes were decades in the making and come back to six key ideas. Finally, I speculate what is next. A related book will be published April 2025 by Black Inc. Link |

9:45-10:30 | AUC Maximisation in Machine Learning Stochastic optimisation algorithms, such as stochastic gradient descent (SGD), update models sequentially with low per-iteration costs, making them well-suited for analysing large streaming datasets. However, most studies focus on classification accuracy, overlooking the critical goal of maximizing the Area Under the ROC Curve (AUC) in imbalanced classification and bipartite ranking. In this talk, I will present our recent work on developing novel SGD-type algorithms for AUC maximisation, examining computational and statistical trade-offs that reveal lower bounds for optimisation error. Additionally, we introduce efficient stochastic primal-dual optimisation algorithms for AUC maximisation, designed to handle streaming data and sparse, high-dimensional settings. This work arises from innovative synergies between machine learning and optimisation. |

14:00-14:45 | Mind the Gap: 3 Ways to Connect Ethical AI Frameworks with Real-World Practice The route toward ethical AI is one we must all walk together. When I began my career in data science, ethical considerations were rarely part of the conversation. Over time, I saw how the drive for rapid growth overshadowed the need to develop AI responsibly. Today, ethical AI is a hot topic, yet we still struggle to turn these conversations into meaningful action. In this talk, I will share my experiences, from data science in the insurance sector to launching AI ventures and academic research, witnessing firsthand what tech companies prioritise and the problem of misaligned incentives. I will discuss why ethics is widely talked about but seldom acted upon, and how we can change that. By focusing on education, building strong communities, and encouraging effective policy, we can bridge the gap and make ethics a practical part of AI development. Together, we can create AI that not only innovates but also serves society with integrity. |

17:30-19:30 | Industry-Academia Networking Event Talk Title 1 Talk Title 2 Multimodal Dense Retrieval in Production Deploying search solutions into production is inherently challenging, with relevance and scalability often being the most difficult aspects to reconcile. Relevance is typically subjective to end users (to varying extents), as such search systems must be tailored to their specific applications to be truly effective. Recent advances in dense embeddings have made it possible to perform high quality retrieval over multimodal data - including images, audio, video, and text; this technology has been a huge unlock for discoverability over unstructured data that was previously difficult to search. In this talk, we will explore use cases for multimodal vector search and how these systems can be implemented to deliver the most value to organisations and end users alike. We will discuss how we fine-tune embedding models and customise search functionalities to build effective and successful information retrieval systems at scale for a variety of domains and use cases.
