 <div class="block">This is a meta-learner that maintains a pool of ordinary
  <a href="../../../../../org/apache/mahout/classifier/sgd/OnlineLogisticRegression.html" title="class in org.apache.mahout.classifier.sgd"><code>OnlineLogisticRegression</code></a> learners. Each
  member of the pool has different learning rates.  Whichever of the learners in the pool falls
  behind in terms of average log-likelihood will be tossed out and replaced with variants of the
  survivors.  This will let us automatically derive an annealing schedule that optimizes learning
  speed.  Since on-line learners tend to be IO bound anyway, it doesn't cost as much as it might
  seem that it would to maintain multiple learners in memory.  Doing this adaptation on-line as we
  learn also decreases the number of learning rate parameters required and replaces the normal
  hyper-parameter search.
  <p/>
  One wrinkle is that the pool of learners that we maintain is actually a pool of
  <a href="../../../../../org/apache/mahout/classifier/sgd/CrossFoldLearner.html" title="class in org.apache.mahout.classifier.sgd"><code>CrossFoldLearner</code></a> which themselves contain several OnlineLogisticRegression
  objects.  These pools allow estimation
  of performance on the fly even if we make many passes through the data.  This does, however,
  increase the cost of training since if we are using 5-fold cross-validation, each vector is used
  4 times for training and once for classification.  If this becomes a problem, then we should
  probably use a 2-way unbalanced train/test split rather than full cross validation.  With the
  current default settings, we have 100 learners running.  This is better than the alternative of
  running hundreds of training passes to find good hyper-parameters because we only have to parse
  and feature-ize our inputs once.  If you already have good hyper-parameters, then you might
  prefer to just run one CrossFoldLearner with those settings.
  <p/>
  The fitness used here is AUC.  Another alternative would be to try log-likelihood, but it is much
  easier to get bogus values of log-likelihood than with AUC and the results seem to accord pretty
  well.  It would be nice to allow the fitness function to be pluggable. This use of AUC means that
  AdaptiveLogisticRegression is mostly suited for binary target variables. This will be fixed
  before long by extending OnlineAuc to handle non-binary cases or by using a different fitness
  value in non-binary cases.</div>
