Human languages trade off complexity against efficiency

The authors trained different language models, from simple statistical models to advanced neural networks, on a database of 41 multilingual text collections comprising a wide variety of text types, which together include nearly 3 billion words across more than 6,500 documents in over 2,000 languages. The trained models were then used to estimate entropy rates, a complexity measure derived from information theory.

Patterns of co-occurrent skills in UK job adverts

This study used a large data set of 65 million job adverts between 2016 and 2022 across the whole of the UK to examine the patterns of skills required together by employers. The authors found clusters of skills that appear together in adverts often, but these clusters do not always agree with how experts group skills based on competencies or qualifications.

Difficult control is related to instability in biologically inspired Boolean networks

Previous work in Boolean dynamical networks has suggested that the number of components that must be controlled to select an existing attractor is typically set by the number of attractors admitted by the dynamics, with no dependence on the size of the network. This study investigates the rare cases of networks that defy this expectation, with attractors that require controlling most nodes.

Urban scaling with censored data

Over the past two decades, urban scaling has become essential for understanding the rural-urban continuum by quantifying how urban characteristics depend on a city’s population size. Nonetheless, access to incomplete datasets about urban features systematically skews the conclusions derived from this theory. To address this limitation, the authors developed a framework that enables urban researchers to draw reliable conclusions about urban scaling, even when dealing with censored datasets.

Statistical complexity of heterogeneous geometric networks

Degree heterogeneity and latent geometry, also referred to as popularity and similarity, are key explanatory components underlying the structure of real-world networks. The relationship between these components and the statistical complexity of networks is not well understood. This study introduces a parsimonious normalised measure of statistical complexity for networks

Cyclic image generation using chaotic dynamics

The authors developed a new approach to generate sequences of related images by extending a type of deep learning model called CycleGAN. This model learns to transform images among three different categories in a cyclic manner. For example, it can turn an image of a T-shirt into a sneaker, then a bag, and back to a T-shirt.

Vertex clustering in diverse dynamic networks

The authors present theoretical and experimental results for spatiotemporal graph k-means (STGkM)—a new unsupervised method to cluster vertices within a dynamic network.
