Properties of the `friend of a friend' model for network generation
Tiffany Y. Y. Lo, Watson Levens, David J. T. Sumpter
The way in which a social network is generated, in terms of how individuals attach to each other, determines the properties of the resulting network. Here we study an intuitively a…
Precision at the indistinguishability threshold: a method for evaluating classification algorithms
David J. T. Sumpter
There exist a wide range of single number metrics for assessing performance of classification algorithms, including AUC and the F1-score (Wikipedia lists 17 such metrics, with 27 d…
Using neuronal models to capture burst and glide motion and leadership in fish
Linnéa Gyllingberg, Alex Szorkovszky, David J. T. Sumpter
While mathematical models, in particular self-propelled particle (SPP) models, capture many of the observed properties of large fish schools, they do not always capture the interac…
Finding analytical approximations for discrete, stochastic, individual-based models of ecology
Linnéa Gyllingberg, David J. T. Sumpter, Åke Brännström
Discrete time, spatially extended models play an important role in ecology, modelling population dynamics of species ranging from micro-organisms to birds. An important question is…
Initiation and spread of escape waves within animal groups
James Herbert-Read, Jerome Buhl, Feng Hu +2
The exceptional reactivity of animal collectives to predatory attacks is thought to be due to rapid, but local, transfer of information between group members. These groups turn tog…
