Two modified DANE algorithms, DANE-LS with line search and DANE-HB with heavy-ball momentum, are proved to converge in fewer communication rounds than plain DANE on strongly convex objectives, including non-quadratic losses.

On Convergence of Distributed Approximate Newton Methods: Globalization, Sharper Bounds and Beyond
Two modified DANE algorithms, DANE-LS with line search and DANE-HB with heavy-ball momentum, are proved to converge in fewer communication rounds than plain DANE on strongly convex objectives, including non-quadratic losses.
