Training on Pascal VOC

[ankitsanand]

Hi Everyone

I am trying to replicate the training of this model on Pascal VOC augmented dataset which has ~11500 training images and 346 validation images.

I have following queries regarding training:

1. For me, a whole pass through the dataset of 11500 images takes approximately 15-16 hours where i use a batch size of 1. Am I missing something or is it similarly slow for everyone?
2. How many complete passes/epochs through complete datasets are required to train model to desired accuracy roughly 70 Miu?
3. How is the trend - Will initial validation Miu accuracy decrease starting from fcn8 and then decrease. Any trend in this whosoever has trained successfully will really be of help.

Regards
