New optimizer ZENITH automates learning rate scheduling for computer vision models

Researchers have introduced ZENITH, a novel optimizer designed to automate learning rate scheduling for deep computer vision models. Unlike existing adaptive optimizers, ZENITH operates with zero computational and memory overhead, and is compatible with regularization techniques. Experiments across various image classification, object detection, and segmentation tasks show that ZENITH achieves higher accuracy in less time compared to baseline methods. Another paper revisits classical assumptions for analyzing stochastic gradient algorithms, focusing on variance assumptions and their relevance in deterministic and stochastic optimization problems.

    ZENITH: Automated Gradient Norm Informed Stochastic Optimization

    arXiv:2601.15212v2 Announce Type: replace Abstract: Training deep computer vision models requires manual oversight or hyperparameter tuning of the learning rate (LR) schedule. While existing adaptive optimizers schedule the LR automatically, they suffer from computational and mem…

    Towards Weaker Variance Assumptions for Stochastic Optimization

    arXiv:2504.09951v2 Announce Type: replace-cross Abstract: We revisit a classical assumption for analyzing stochastic gradient algorithms where the squared norm of the stochastic subgradient (or the variance for smooth problems) is allowed to grow as fast as the squared norm of th…
