Lévy walkers inside spherical shells with absorbing boundaries: Towards settling the optimal Lévy walk strategy for random searches
L. G. P. Caramês, Y. B. Matos, F. Bartumeus +5
The Lévy flight foraging hypothesis states that organisms must have evolved adaptations to exploit Lévy walk search strategies. Indeed, it is widely accepted that inverse square Lé…
AugLiChem: Data Augmentation Library of Chemical Structures for Machine Learning
Rishikesh Magar, Yuyang Wang, Cooper Lorsung +4
Machine learning (ML) has demonstrated the promise for accurate and efficient property prediction of molecules and crystalline materials. To develop highly accurate ML models for c…
Comment on "Inverse Square Lévy Walks are not Optimal Search Strategies for d 2" [Phys. Rev. Lett. 124, 080601 (2020)]
S. V. Buldyrev, E. P. Raposo, F. Bartumeus +4
It is widely accepted that inverse square Lévy walks are optimal search strategies because they maximize the encounter rate with sparse, randomly distributed, replenishable targets…
bigMap: Big Data Mapping with Parallelized t-SNE
Joan Garriga, Frederic Bartumeus
We introduce an improved unsupervised clustering protocol specially suited for large-scale structured data. The protocol follows three steps: a dimensionality reduction of the data…
First-passage times in multi-scale random walks: the impact of movement scales on search efficiency
Daniel Campos, Frederic Bartumeus, E. P. Raposo +1
An efficient searcher needs to balance properly the tradeoff between the exploration of new spatial areas and the exploitation of nearby resources, an idea which is at the core of…
Expectation-Maximization Binary Clustering for Behavioural Annotation
Joan Garriga, John R. Palmer, Aitana Oltra +1
We present a variant of the well sounded Expectation-Maximization Clustering algorithm that is constrained to generate partitions of the input space into high and low values. The m…
The effects of spatially heterogeneous prey distributions on detection patterns in foraging seabirds
Octavio Miramontes, Denis Boyer, Frederic Bartumeus
Many attempts to relate animal foraging patterns to landscape heterogeneity are focused on the analysis of foragers movements. Resource detection patterns in space and time are not…
