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…
The Lost Art of Mathematical Modelling
Linnéa Gyllingberg, Abeba Birhane, David J. T. Sumpter
We provide a critique of mathematical biology in light of rapid developments in modern machine learning. We argue that out of the three modelling activities -- (1) formulating mode…
The games we play: critical complexity improves machine learning
Abeba Birhane, David J. T. Sumpter
When mathematical modelling is applied to capture a complex system, multiple models are often created that characterize different aspects of that system. Often, a model at one leve…
Friend of a friend models of network growth
Watson Levens, Alex Szorkovszky, David J. T. Sumpter
One of the best-known models in network science is preferential attachment. In this model, the probability of attaching to a node depends on the degree of all nodes in the populati…
Spontaneous emergence of self-replication in chemical reaction systems
Yu Liu, David Sumpter
Explaining the origin of life requires us to explain how self-replication arises. To be specific, how can a self-replicating entity develop spontaneously from a chemical reaction s…
Emergent Structural Mechanisms for High-Density Collective Motion Inspired by Human Crowds
Arianna Bottinelli, David T. J. Sumpter, Jesse L. Silverberg
Collective motion of large human crowds often depends on their density. In extreme cases like heavy metal concerts and Black Friday sales events, motion is dominated by physical in…
An efficient method for sorting and selecting for social behaviour
Alex Szorkovszky, Alexander Kotrschal, James E. Herbert Read +3
In this article we provide a systematic experimental method for sorting animals according to socially relevant traits, without assaying them or even tagging them individually. Inst…
Identifying differences in the rules of interaction between individuals in moving animal groups
Timothy. M. Schaerf, James E. Herbert-Read, Mary R. Myerscough +2
Collective movement can be achieved when individuals respond to the local movements and positions of their neighbours. Some individuals may disproportionately influence group movem…
An Experimental Study of Segregation Mechanisms
Milena Tsvetkova, Olof Nilsson, Camilla Öhman +2
Segregation is widespread in all realms of human society. Several influential studies have argued that intolerance is not a prerequisite for a segregated society, and that segregat…
Body size affects the strength of social interactions and spatial organisation of a schooling fish (Pseudomugil signifer)
Maksym Romenskyy, James E. Herbert-Read, Ashley J. W. Ward +1
While a rich variety of self-propelled particle models propose to explain the collective motion of fish and other animals, rigorous statistical comparison between models and data r…
Escape path complexity and its context dependency in Pacific blue-eyes (Pseudomugil signifer)
James E. Herbert-Read, Ashley J. W. Ward, David J. T. Sumpter +1
The escape trajectories animals take following a predatory attack appear to show high degrees of apparent 'randomness' - a property that has been described as 'protean behaviour'.…
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…
Individual rules for trail pattern formation in Argentine ants (Linepithema humile)
Andrea Perna, Boris Granovskiy, Simon Garnier +5
We studied the formation of trail patterns by Argentine ants exploring an empty arena. Using a novel imaging and analysis technique we estimated pheromone concentrations at all spa…
