6a.022.UL - Mitigating Concept Drift for Time-Varying Domains Through Adaptive Learning

Project - Summary

Adaptive techniques for concept drift detection are a necessary topic of exploration, as it is guaranteed that as time passes, underlying conditions will shift. As these shifts occur, they can cause major impacts on predictions for the future both short and long term. Some examples of drifting conditions are:

  1. People seeking to hoodwink anomaly detection systems in order to commit fraud.
  2. People deliberately exploiting discovered knowledge for hostile purposes, i.e. discoveries fount via hotspot analysis and association mining.
  3. A sudden increase/decrease in the number of patients in hospitals in a specific region
  4. A sudden increase/decrease in the spending of clients in a specific area or type of purchase item

Typically, changes to underlying conditions are rarely advertised and it is unknown when the impact of such changes will be felt. One of the more difficult portions of this research is determining when and how to update knowledge, in a computationally inexpensive manner. This is due to the “expiration date” that exists on all learned data.
