I am on the search for some data with a time stamp attribute that has got concept drift occurring within it to complete the experimentations. The on-line learning algorithm being used is a tree induction classifier which detects concept drift in the presence of noise and then removes invalid examples. A large database would be preferable to aid extraction of batches. Reference of work to date: Black, M., Hickey, R.J.
