We would love to include those, but we didn't find the implementation for the tested models for Theano, yet. Do you have link? You can also submit your own Benchmarks via PR, if you'd like to.
VGG: https://gist.github.com/baraldilorenzo/07d7802847aaad0a35d3
For Googlenet, sadly not yet: https://github.com/fchollet/keras/issues/302
I'd also try some non conv, RNN/LSTM stuff btw. Those are of special interest to me, but also, keras has some great models there.
I haven't run any in a while so I don't have the data myself, unfortunately.
Great work btw.
What was the motivation to build leaf?
