Research Seminar – Educating with Responsible AI

Speaker: Dr Lily Clements from IDEMS International Title: Educating with Responsible AI Abstract: There is currently immense interest and awareness in the ethics of AI. In 2022, we were tasked with developing a Responsible AI course for the Turing Institute titled ‘How Data Lies’. In August 2023, we were tasked to give a double course in Burkina Faso

Research Seminar – Dynamic SIR Models with an Exact Solution

Title: Dynamic SIR Models with an Exact Solution Speaker: Prof. Dr. Delfim F. M. Torres Affiliation: University of Aveiro, Portugal Abstract: We investigate an epidemic model based on Bailey’s continuous differential system. In the continuous time domain, we extend the classical model to time-dependent coefficients and present an alternative solution method to Gleissner’s approach. If the coefficients are constant,

Maiden Edition of the Francis Allotey Public Lecture

As part of its 10-year anniversary celebration under the theme: Developing versatile and innovative STEM leaders for Africa’s scientific excellence and socio-economic development, AIMS Ghana has instituted an annual public lecture in honor of the late Professor Francis Allotey who founded the institute and this event will be scheduled for August 9th every year. In

Household epidemic models and Poisson driven McKean-Vlasov equations

Abstract: I will present the result of a joint work with Pr. Etienne Pardoux (Aix-Marseille Université), in which we studied an epidemic spreading in a population consisting of a collection of households, each containing a small number of individuals. Individuals have frequent contacts with other members of their household, and occasional contacts with individuals chosen at

Stochastic Epidemic Models with Partial Information and Dark Figure Estimation

Abstract:  Mathematical models of epidemics such as the current COVID-19 pandemics often use compartmental models dividing the population into several compartments. Based on a microscopic setting describing the temporal evolution of the subpopulation sizes in the compartments by stochastic counting processes one can derive macroscopic models for large populations describing the average behavior by associated

On the geometry of some rough Weierstrass and Takagi type curves: SBR measure and local time

Speaker: Prof. Dr. Peter Imkeller (Institute for Mathematics, Humboldt-University of Berlin, Germany) Abstract: We investigate geometric properties of graphs of Weierstrass or Takagi type functions, represented by series based on smooth functions. They are Hölder continuous, and can be embedded into smooth dynamical systems, where their graphs emerge as pullback attractors. It turns out that occupation measures

Exact simulation of the first time a diffusion process overcomes a given threshold

Abstract: The aim of our study is to propose a new exact simulation method for the first passage time (FPT) of a diffusion process (X_t , t ≥ 0). We shall consider either a continuous diffusion process (in collaboration with Cristina Zucca, University of Turin) or a jump diffusion (in collaboration with Nicolas Massin, University of

Stability for some impulsive neutral stochastic functional integro-differential equations driven by fractional Brownian motion/ Global dynamics of a spatiotemporal cellular model for the Hepatitis C virus infection with Hattaf-Yousfi functional response
