報告摘要:
Convex optimization models have been widely used in many applications such as machine learning and data science. However, the huge computation for the involved potentially large-scale problems has prevented their deployments in resource-limited devices. In our work, we design efficient second-order algorithms for the structured convex composite programming problems, which fully exploit the structure of the data and the underlying Hessians to highly reduce the computational cost. Dimension reduction techniques are also designed to further accelerate the computation, especially for the high-dimensional cases.
