On the efficiency of Stochastic Quasi-Newton Methods for Deep Learning
, 2023 While first-order methods are popular for solving optimization problems that arise in large-scale deep learning problems, they come with some acute deficiencies.

Mesh Processing Non‐Meshes via Neural Displacement Fields
Computer Graphics Forum, EarlyView.Abstract Mesh processing pipelines are mature, but adapting them to newer non‐mesh surface representations—which enable fast rendering with compact file size—requires costly meshing or transmitting bulky meshes, negating their core benefits for streaming applications.

Progressively Projected Newton's Method
Computer Graphics Forum, EarlyView.Abstract Newton's Method is widely used to find the solution of complex non‐linear simulation problems. To guarantee a descent direction, it is common practice to clamp the negative eigenvalues of each element Hessian prior to assembly—a strategy known as Projected Newton (PN)—but this perturbation often hinders convergence.

Karush-Kuhn-Tucker systems: regularity conditions, error bounds and a class of Newton-type methods
, 2003 We consider optimality systems of Karush-Kuhn-Tucker (KKT) type, which arise, for example, as primal-dual conditions characterizing solutions of optimization problems or variational inequalities.

Hierarchical Optimization of the As‐Rigid‐As‐Possible Energy
Computer Graphics Forum, EarlyView.Abstract The As‐Rigid‐As‐Possible (ARAP) energy [SA07] has become a versatile ingredient in various geometry processing and machine learning methods. The classic method for its minimization is a block coordinate descent, alternating between local rotation estimation and a global linear solve, which converges slowly for large problem instances.

Computer Graphics Forum, EarlyView.Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

Fast Nodal Hessian Computation for Peridynamic Fracture Simulation
Computer Graphics Forum, EarlyView.A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

European Journal of Oral Sciences, EarlyView.Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Inexact Quasi-Newton methods for sparse systems of nonlinear equations
, 2001 In this paper, we present the results obtained by solving consistent sparse systems of n nonlinear equations F(x) = 0, by a Quasi-Newton method combined with a p block iterative row-projection linear solver of Cimmino type, 1 less than or equal to p

Black Fugitivity in the Sporting Workplace: The Story of Eniola Aluko
Gender, Work &Organization, EarlyView.ABSTRACT Being a Black fugitive involves constant movement: to find and cultivate spaces of safety and hope. In this paper, I curate a sporting archive about the UK Black women's elite football player Eniola Aluko to read her as a Black fugitive. I demonstrate how she traversed a racist and anti‐Black sporting workplace—where she was unfairly demonized
