Model fit and parameter uncertainty in amortized variational inference based item response theory

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Amortized variational inference (AVI) has become a popular, computationally efficient alternative to marginal maximum likelihood estimation (MML) for estimating high‐dimensional item response theory models on large datasets. However, currently the AVI framework lacks methods to assess model fit and determine parameter uncertainty.

Parallel Vectors Extraction using Bézier Clipping

Computer Graphics Forum, EarlyView.
Abstract In this paper, we propose a novel local feature extraction algorithm for the parallel vectors (PV) operator. Our method is based on Bézier clipping, which is a bracketing‐based root finding method that is commonly‐used in computer‐aided geometric design.

Fatigue Behavior of Post‐Processed Additively Manufactured 316L Stainless Steel: Experiments and Fatigue Damage Modeling

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study experimentally and numerically investigates fatigue damage in additively manufactured 316L stainless steel produced by selective laser melting using the powder bed fusion–laser beam process. More than 100 specimens were tested under tensile and strain‐controlled fatigue loading to evaluate the effects of surface condition, hot ...

Geometric Newton-Raphson methods for plane curves [PDF]

, 2012
Our paper reviews Kallay's results on a geometric version of the classic Newton-Raphson method, in the context of plane curve queries, e.g. curve-curve intersection, point-curve distance computation.

Design and Applicability of Two-Step Fractional Newton–Raphson Method

Fractal and Fractional
Developing two-step fractional numerical methods for finding the solution of nonlinear equations is the main objective of this research article. In addition, we present a detailed study of convergence analysis for the methods that have been proposed.

Geometric Newton-Raphson Methods for Plane Curves

Acta Cybernetica, 2013
Our paper reviews Kallay's results on a geometric version of the classic Newton-Raphson method, in the context of plane curve queries, e.g. curve-curve intersection, point-curve distance computation. Variants of the geometric Newton-Raphson methods are proposed and empirically verified.

Debt Aversion: Theory and Measurement

International Economic Review, EarlyView.
ABSTRACT We propose a model of debt aversion and conduct an experiment with real debt and saving contracts to jointly elicit debt aversion and preferences over time, risk, and intertemporal losses. We find that 89% of participants are debt averse, which strongly influences their choices.

Another Look at the (Ir)Relevance of Long‐Run Risks for Equity Risk Premia

Journal of Money, Credit and Banking, EarlyView.
Abstract I investigate the empirical asset pricing implications of a three‐factor macro model that extends the baseline consumption model Consumption Capital Asset Pricing Model (CCAPM) by adding the innovations in expected long‐run consumption growth (consumption growth news) and expected long‐run consumption variance (variance news) as risk factors ...

THE NEWTON-RAPHSON METHOD OF REAL-VALUED FUNCTIONS IN DISCRETE METRIC SPACE [PDF]

. This paper studies the Newton-Raphson method to approximate a root of a real-valued function in one-dimensional real discrete metric space. The method involves a derivative and is considered to be convergent very fast.
