or a full approximation to it in a second-order method is prohibitive, both in terms of memory requirements and computational cost per iteration. Hence, to be practical, layer-wise block-diagonal approximations to these matrices are usually used. Here we describe
second-order quasi-Newton (QN), natural gradient (NG), and generalized Gauss-Newton (GGN) methods of this type that are competitive with and often outperform first-order methods. These methods include those that use layer-wise (i) Kronecker-factored BFGS and
L-BFGS QN approximations, (ii) tensor normal covariance and (iii) mini-block Fisher matrix approximations, and (iv) Sherman-Morrison-Woodbury based variants of NG and GGN methods.</span></p>

Princeton University. Goldfarb spent two years as a post-doc at the Courant Institute. In 1968, he co-founded the CS Department at the City College of New York, serving 14 years on its faculty. During the 1979–80 academic year, he was a Visiting Professor
in the CS and ORIE Departments at Cornell University. In 1982, Goldfarb joined the IEOR Department at Columbia, serving as Chair from 1984–2002. He also served as Interim Dean of Columbia’s School of Engineering and Applied Science during the 1994–95 and 2012–13
