OCP-LS: An Efficient Algorithm for Visual Localization
This addresses optimization efficiency for visual localization tasks, though it appears incremental as it builds on existing OCP methods.
The paper tackles large-scale optimization problems in deep learning for visual localization by proposing a second-order algorithm that approximates Hessian diagonal elements, achieving competitive accuracy with faster convergence, enhanced stability, and improved noise robustness on standard benchmarks.
This paper proposes a novel second-order optimization algorithm. It aims to address large-scale optimization problems in deep learning because it incorporates the OCP method and appropriately approximating the diagonal elements of the Hessian matrix. Extensive experiments on multiple standard visual localization benchmarks demonstrate the significant superiority of the proposed method. Compared with conventional optimiza tion algorithms, our framework achieves competitive localization accuracy while exhibiting faster convergence, enhanced training stability, and improved robustness to noise interference.
