Events for 16 January 2020
The use of AI across academia, industry and the public sector is widespread. Inn addition, access to the methods and technology to build and deploy AI systems is becoming increasingly democratised through open-source software, publications, and online tutorials as well as cheapening compute resources. Although this ease of access is positive, allowing more people to leverage the power of AI, education in understanding the potential negative consequences of its use can be lacking, both at the development as well as regulatory level. Furthermore, biases can manifest themselves at all stages in the development and deployment pipeline of AI models, from the project formulation stage to the dataset creation and the visualisation of results. In this talk I will discuss work done in collaboration with the United Nations in which we specifically highlight the risks surrounding the ability to generate text using language models and the potential implications for political stability. Additionally, I will discuss further work the UN is conducting in mapping such biases in AI systems and understanding how they can translate into human level harms. I will close with a collection of broad recommendations going forward for addressing the biases and mitigating the associated harms.

Arthur Soulié: A unified functorial construction of homological representations of families of groups
Many families of groups, such as braid groups, have a representation theory of wild type, in the sense that there is no known classification schema. Hence it is useful to shape constructions of linear representations for such families of groups to understand their representation theory. I will present a unified functorial construction of homological representations for these families of groups, which is a joint work in progress with Martin Palmer. For instance, this construction provides the family of Lawrence-Bigelow representations for braid groups. Under some additional assumptions, general notions of polynomiality on functors are a useful tool to classify these representations.
