Does Vowpal Wabbit automatically shuffle its data after every epoch/pass? I'm hoping the created cache file will contain the shuffling meta-data that is necessary for online algorithms like VW's default online SGD method. E.g.
vw -d train.txt -c --passes 50 -f train.model
If not, I have a backup script that manually shuffles the data on every pass
# Create the initial regressor file
vw -d train.txt -f train.model
# For the next 49 passes, shuffle and then update the regressor file
for i in {0..49}
do
<some script: train.txt --> shuffled_data.txt>
vw -d shuffled_data.txt -i train.model -f train.model
done
If VW doesn't automatically shuffle, then is there a more efficient way of performing the above code block? VW's wiki is unfortunately unclear with regards to this. Thanks.
