      I am -loving- this combined Rectifed Adam (RAdam) + LookAhead optimizer. It's freaky stable and powerful, especially for my purposes. Only weird thing to keep in mind- I've had to multiply my learning rates by over 100x to maximally take advantage.https://medium.com/@lessw/new-deep-learning-optimizer-ranger-synergistic-combination-of-radam-lookahead-for-the-best-of-2dc83f79a48d …

      how about LA Adam on convnets? Image classification community never truly switch to Adam because SGD almost always give 1% more accuracy (important so that you can write papers.)

      Then they better thoroughly prove so for various models. If it really has both faster convergence AND accuracy.
