Throwing away stale data

[vahuja4]

@chschroeder - AL deals primarily with selecting data points which need to be added to the training set. Can it also be used to select datapoints which need to be purged out of the training set because they are no longer useful?

I haven't come across it yet, but there are approaches like core sets or submodular optimization if you want to downsize your dataset.
