Parameters Estimation of a Lotka-Volterra Model in an Application for Market Graphics Processing Units

Normatov Dzhakhongir, Mercorelli Paolo

Annals of Computer Science and Information Systems

2022

Vol. 30

935--938

In this paper, a least squares method is used to estimate parameter values in the Lotka-Volterra model. The data used are graphics processing units (GPU) shipment worldwide by three key competitors, namely Nvidia, Intel, and AMD. The goal is to quantify the parameter values of a model with minimal error to qualitatively solve the problem and fit the raw data as closely as possible. Based on the real measurements, the predator between the competitors is recognized through the identification procedure comparing the sign of the coefficients with the original Lotka-Volterra model structure.
