I reran the CIFAR100 experiment ONCE for each optimizer (cf. https://github.com/tdeboissiere/DeepLearningImplementations/tree/master/Eve) and this time, Eve outperforms the other 2.

Yup! You're right - it's a typo in the paper. Thank you very much for pointing this out - we'll rectify this as soon as possible.
from sgd-feedback.
By the way, what were the best parameters (learning rate, decay) for Eve on CIFAR 100 ?
I am unable to reproduce your results on this dataset.

Hi @tdeboissiere: for that experiment the best parameters for Eve are learning rate 0.0001 and decay 0.0001. What results did you get?
from sgd-feedback.
Eve actually did worse than Adam and SGD. My best guess is that without a lower learning rate + annealing, training is quite hard. I also had to switch on BatchNorm to get any optimizer to work.
I tried both you implementation and mine with much the same results.
What were the best parameters for SGD and Adam ?
from sgd-feedback.
Did you try the learning rates I mentioned?
The best parameters for SGD, Adam:
SGD Nesterov: lr 0.01, decay 0.0001
Adam: lr 0.0001, decay - turns out to not have been saved because of a previous bug in Keras. But I would imagine it's the same as for Eve: 0.0001. I will try to run the cross-validation again when I can

I am going to run the experiments on CIFAR100 with the best parameters you found. Did you use BatchNorm in the end ?
from sgd-feedback.
No, I didn't. The exact model is in src/models.py (get_big_cnn_model)
