Tractable structured natural gradient descent using local parameterizations
Wu Lin, Frank Nielsen, Mohammad Emtiyaz Khan +1
Natural-gradient descent (NGD) on structured parameter spaces (e.g., low-rank covariances) is computationally challenging due to difficult Fisher-matrix computations. We address th…
