Euclid preparation: LXVII. Deep learning true galaxy morphologies for weak lensing shear bias calibration

Astronomy & Astrophysics
To date, galaxy image simulations for weak lensing surveys usually approximate the light profiles of all galaxies as a single or double Sérsic profile, neglecting the influence of galaxy substructures and morphologies deviating from such a simplified ...

Improved Learning Algorithms of SLFN for Approximating Periodic Function

2008
In this paper, three improved Extreme Learning Machines (ELMs) are proposed to approximating periodic function. According to Fourier series expansion theory, the hidden neurons activation functions in the improved ELM are a class of sine and cosine functions.

A growing and pruning sequential learning algorithm of hyper basis function neural network for function approximation

Neural Networks, 2013
Radial basis function (RBF) neural network is constructed of certain number of RBF neurons, and these networks are among the most used neural networks for modeling of various nonlinear problems in engineering. Conventional RBF neuron is usually based on Gaussian type of activation function with single width for each activation function.

A novel iterative algorithm for approximating equivalent circuits of numerical transfer functions

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2016
AbstractRecently, we presented a novel method for pole residue equivalent system solver (PRESS). In this work, we provide the exact solution of local fit types 1, 2, and 3. We also modify the original algorithm to conduct parallel search for optimal solution across all frequencies, instead of targeting only the peak error.

An Adaptive Algorithm for Weighted Approximation of Singular Functions over $\mathbb{R}$

SIAM Journal on Numerical Analysis, 2013
We study the $\omega$-weighted $L^p$ approximation ($1\le p\le\infty$) of piecewise $r$-smooth functions $f:\mathbb{R}\to\mathbb{R}$. Approximations $\mathcal{A}_nf$ are based on $n$ values of $f$ at points that can be chosen adaptively. Assuming that the weight $\omega$ is Riemann integrable on any compact interval and asymptotically decreasing, a ...

The convergence rate of the sandwich algorithm for approximating convex functions

Computing, 1992
Interval bisection, slope bisection, maximum error rule and chord rule are considered as four natural rules leading to different versions of the sandwich algorithm for approximating a convex function of one variable over an interval by evaluating the function and its derivative at a sequence of points.
