New spectral conjugate gradient algorithm developed for optimization and classification

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new spectral conjugate gradient algorithm that modifies the classic Hestenes--Stiefel method. This new algorithm aims to preserve anti-jamming characteristics while ensuring sufficient descent properties. It incorporates a modified secant equation derived from the update scheme, leading to a memoryless BFGS update. The spectral parameter is adjusted to align with the BFGS direction within a least-squares framework, and it has been tested on optimization models and applied to a robust binary classification model using a support vector machine.
