This model is a replication of the model described in the GoogleNet publication. We would like to thank Christian Szegedy for all his help in the replication of GoogleNet model.
Differences: - not training with the relighting data-augmentation; - not training with the scale or aspect-ratio data-augmentation; - uses "xavier" to initialize the weights instead of "gaussian"; - quick_solver.prototxt uses a different learning rate decay policy than the original solver.prototxt, that allows a much faster training (60 epochs vs 250 epochs);
The bundled model is the iteration 2,400,000 snapshot (60 epochs) using quick_solver.prototxt
This bundled model obtains a top-1 accuracy 68.7% (31.3% error) and a top-5 accuracy 88.9% (11.1% error) on the validation set, using just the center crop. (Using the average of 10 crops, (4 + 1 center) * 2 mirror, should obtain a bit higher accuracy.)
Timings for bvlc_googlenet with cuDNN using batch_size:128 on a K40c: - Average Forward pass: 562.841 ms. - Average Backward pass: 1123.84 ms. - Average Forward-Backward: 1688.8 ms.
This model was trained by Sergio Guadarrama @sguada
This model is released for unrestricted use.
