This adaptive Hoeffding Tree uses ADWIN to monitor performance of branches on the tree and to replace them with new branches when their accuracy decreases if the new branches are more accurate. See details in: Adaptive Learning from Evolving Data Streams. Albert Bifet, Ricard … NettetIt implements Hoeffding adaptive trees (section 6.3.5) for data streams in C++ and has been used extensively at Huawei. Hoeffding adaptive trees adapt to changes in streams, a huge advantage since standard decision trees are built using a snapshot of data and cannot evolve over time.
