Improving Levenberg-Marquardt Algorithm for Neural Networks [PDF]
arXiv.org, 2022 We explore the usage of the Levenberg-Marquardt (LM) algorithm for regression (non-linear least squares) and classification (generalized Gauss-Newton methods) tasks in neural networks.

Applicability of Common Algorithms in Species–Area Relationship Model Fitting
Diversity, 2022 The species–area relationship (SAR) describes a law of species richness changes as the sampling area varies. SAR has been studied for more than 100 years and is of great significance in the fields of biogeography, population ecology, and conservation ...

Local Levenberg-Marquardt Algorithm for Learning Feedforwad Neural Networks
Journal of Artificial Intelligence and Soft Computing Research, 2020 This paper presents a local modification of the Levenberg-Marquardt algorithm (LM). First, the mathematical basics of the classic LM method are shown. The classic LM algorithm is very efficient for learning small neural networks.
