Homogeneity and Sparsity Pursuit Using Robust Adaptive Fused Lasso

Australian &New Zealand Journal of Statistics, EarlyView.
ABSTRACT Fused lasso regression is a popular method for identifying homogeneous groups and sparsity patterns in regression coefficients based on either the presumed order or a more general graph structure of the covariates. However, the traditional fused lasso may yield misleading outcomes in the presence of outliers.

Twenty‐Year Trends in Colectomy Rates and Advanced Therapy Prescribing in Lothian, Scotland

Alimentary Pharmacology &Therapeutics, EarlyView.
Prescribing of first‐line advanced therapy increased from 0 in 2004 to 115 in 2023, and absolute colectomy numbers decreased from 42 in 2004 to 7 in 2023. Piecewise linear regression found a join point in 2013 for both increased advanced therapy prescribing and decreased colectomy rates. ABSTRACT Background The impact of advanced therapy prescribing on

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Neural Geometry Processing via Spherical Neural Surfaces

Computer Graphics Forum, EarlyView.
Abstract Neural surfaces (e.g., neural map encoding, deep implicit, and neural radiance fields) have recently gained popularity because of their generic structure (e.g., multi‐layer perceptron) and easy integration with modern learning‐based setups. Traditionally, we have a rich toolbox of geometry processing algorithms designed for polygonal meshes to

Corotational Hinge‐based Thin Plates/Shells

Computer Graphics Forum, EarlyView.
Abstract We present six thin plate/shell models, derived from three distinct types of curvature operators formulated within the corotational frame, for simulating both rest‐flat and rest‐curved triangular meshes. Each curvature operator derives a curvature expression corresponding to both a plate model and a shell model.
