In this paper, researchers tackle the challenge of applying second-order optimization techniques to modern deep learning, despite their theoretical benefits being hindered by computational complexity issues. They propose Ginger, an eigendecomposition-based method for efficiently computing the inverse of the generalized Gauss-Newton matrix, which enjoys linear memory and time complexity. This approach allows for more accurate conditioning matrices and is demonstrated on various tasks with different model architectures. The code is publicly available.

This paper makes deep learning faster and better by solving a big problem. Right now, we can’t use powerful optimization techniques because they’re too hard to compute. But the researchers found a way to make it work by inventing a new method called Ginger. It’s like a shortcut that makes the calculations much faster. They tested it on different tasks with different models and it worked really well! Now you can try it out for yourself, as the code is available online.
