Reducing climate risk in energy system planning: a posteriori time series aggregation for models with storage
Adriaan P Hilbers, David J Brayshaw, Axel Gandy
The growth in variable renewables such as solar and wind is increasing the impact of climate uncertainty in energy system planning. Addressing this ideally requires high-resolution…
Joint Entropy Search for Multi-objective Bayesian Optimization
Ben Tu, Axel Gandy, Nikolas Kantas +1
Many real-world problems can be phrased as a multi-objective optimization problem, where the goal is to identify the best set of compromises between the competing objectives. Multi…
Age-stratified epidemic model using a latent marked Hawkes process
Stamatina Lamprinakou, Axel Gandy
We extend the unstructured homogeneously mixing epidemic model introduced by Lamprinakou et al. [arXiv:2208.07340] considering a finite population stratified by age bands. We model…
Can a latent Hawkes process be used for epidemiological modelling?
Stamatina Lamprinakou, Axel Gandy, Emma McCoy
Understanding the spread of COVID-19 has been the subject of numerous studies, highlighting the significance of reliable epidemic models. Here, we introduce a novel epidemic model…
A Proper Concordance Index for Time-Varying Risk
A. Gandy, T. J. Matcham
Harrel's concordance index is a commonly used discrimination metric for survival models, particularly for models where the relative ordering of the risk of individuals is time-inde…
