Caputo‐based fPINNs accurately solve fractional ODEs and PDEs while exposing an accuracy–cost trade‐off driven by the history‐dependent fractional derivative. Temporal collocation and shorter time windows are the most effective strategies for improving early‐time accuracy without unnecessary spatial refinement.

Extending geometric discretisation
THESIS 6816Geometric discretisation (GD) [1] is a novel approach capable of capturing topological properties, based on a correspondence between discrete objects and operations on a triangulation with continuum ones on a manifold.

Behavioural state identification from ultra‐high‐frequency movement data
Abstract The hidden Markov model (HMM) is a central framework for identifying behavioural state changes from animal movement data. In this context, movement is typically represented as a sequence of observed metrics, such as step length and turning angle distributions, generated by an unobserved behavioural state process.

Abstract We propose the novel p‐branch‐and‐bound method for solving two‐stage stochastic programming problems whose deterministic equivalents are represented by non‐convex mixed‐integer quadratically constrained quadratic programming (MIQCQP) models. The precision of the solution generated by the p‐branch‐and‐bound method can be arbitrarily adjusted by

A Constructivist Approach to Continuous Variables in Macroscopic Social Research
ABSTRACT This paper offers a constructivist approach to the analysis of continuous variables in macroscopic social research. Scientific constructivists have well developed ideas about how categories are situated in minds as bounded regions in conceptual space.

The Architecture of Language Discretisation
This comprehensive analysis investigates the critical role of tokenisation—the conversion of continuous text into discrete numerical representations—within the architecture of large language models (LLMs). It argues that this process, far from being a simple preprocessing step, fundamentally dictates a model's computational efficiency, morphological ...
