This processor classifies a news video into anchorshots and news report shots, by

applying a decision tree to each example. The decision tree has to be learned using

RapidMiner, as not Decision Tree Learner is implemented in the streams framework


Parameter Type Description Required

predictionkey String Sets the key under which the classifier shall store the predicted
