Journal of Applied Analysis, 2020 Abstract In this article, we describe a function fitting method that has potential applications in machine learning and also prove relevant theorems. The described function fitting method is a convex minimization problem which can be solved using a gradient descent algorithm.

Non-Parametric Function Fitting
Journal of the Royal Statistical Society Series B: Statistical Methodology, 1972 Summary In this note we consider the problem of fitting a general functional relationship between two variables. We require only that the function to be fitted is, in some sense, “smooth”, and do not assume that it has a known mathematical form involving only a finite number of unknown parameters.

On the use of the stepped isostress method in the prediction of creep behavior of polyamide 6
Fracture and Structural Integrity, 2022 The stepped isostress method (SSM) is an advanced technique which allows the prediction of the long-term behavior and enables the construction of creep master curves of materials with short-term experimental tests. However, the performance of this method

Fitting the psychometric function [PDF]
Perception & Psychophysics, 1999 A constrained generalized maximum likelihood routine for fitting psychometric functions is proposed, which determines optimum values for the complete parameter set--that is, threshold and slope--as well as for guessing and lapsing probability. The constraints are realized by Bayesian prior distributions for each of these parameters.

Visual function and fitness to drive [PDF]
British Medical Bulletin, 2008 Driving is recognized to be a visually intensive task and accordingly there is a legal minimum standard of vision required for all motorists. The purpose of this paper is to review the current United Kingdom (UK) visual requirements for driving and discuss the evidence base behind these legal rules.

Testing different function fitting methods for mobile eye-tracker calibration
Journal of Eye Movement Research, 2023 During calibration, an eye-tracker fits a mapping function from features to a target gaze point. While there is research on which mapping function to use, little is known about how to best estimate the function's parameters.
