New paper offers information-theoretic analysis of SGD methods

By PulseAugur Editorial · [1 sources] ·

A new paper proposes an information-theoretic analysis of stochastic gradient descent (SGD) and its variants, offering an alternative to traditional geometric approaches. The research demonstrates that a preconditioned SGD step is equivalent to the posterior-mean update of a Gaussian Bayes model. This framework allows for a precise breakdown of SGD's one-step regret into intrinsic-time cost and changes in comparator information, providing a unified identity that encompasses various SGD aspects like convex convergence, saddle-point escape, and generalization.

    Exact information accounting for SGD methods

    arXiv:2610.00446v1 Announce Type: cross Abstract: As an alternative to the standard geometric analyses, we give an exact, information-theoretic analysis of stochastic gradient descent (SGD) and its variants. We show that a preconditioned SGD step is the posterior-mean update of a…
