All of those "training accuracy" lines hidden in there will give us a good idea
of how well the algorithm is performing. To get a quick plot of them:
- cat ~/Experiments/tagger-beam1.log | py-grep-plot 'training accuracy: ([.\d]+)'
+ cat ~/Experiments/tagger-beam1.log | py-grep-plot -r 'training accuracy: ([.\d]+)'
If you have your matplotlib configured with an interactive backend, you should
see a nice little plot appear.
