Nonlinear regression. A JavaScript code with gradient descent optimized with ADAM.
Multivariate nonlinear regression. I am working on a predictive model for water alkaline electrolyzers (AWE). The literature is not particularly generous regarding dynamic models. The only model available and well referenced in the literature is Ulberg’s [1].This was a six-parameter semi-empirical model consisting of a non-linear function. The Vcell is the potential difference to be applied to the electrolyser to obtain the current I. The goal is to model the six parameters so that the function “fits” the electrolyzer experimental…
