Research
The aim of DUST is to create new methods for dynamically assimilating data into agent-based models which will allow us to more reliably simulate the daily ebb abd flow of urban systems. This is a big challenge, so there are a number of different related research questions that DUST, and other projects, are working on. For publications or project documention see the publications page.

Uncertainty in agent-based models for smart city forecasts
Full details on the Alan Turing Institute Website
Individual-level modelling approaches, such as agent-based modelling (ABM), are ideally suited to modelling the behaviour and evolution of social systems. However, there is inevitably a high degree of uncertainty in projections of social systems, so one of the key challenges facing the discipline is the quantification of uncertainty within the outputs of these models. The aim of this project is to develop methods that can be used to better understand uncertainty in individual-level models. In particular, it will explore and extend the state-of-the-art in two related areas: ensemble modelling and associated emulators for use in individual-level models.
Probabilistic Programming and Data Assimilation for Next Generation City Simulation
This Leeds Institute for Data Alaytics internship project, which is being funded by Improbable, is experimenting with the use of a Bayesian inference and probabilistic programming languages, such as Keanu to better capture the uncertainty in simualtions of human systems.
