Learning for User Adaptive Systems: Likely Pitfalls and Daring Rescue

Adaptive user interfaces adapt themselves to the user by reasoning about the user and refining their internal model of the user's needs. In machine learning, artificial systems learn how to perform better through experience. By observing examples from a sample, the learning algorithm tries to induce a hypothesis which approximates the target function. It seems obvious, that machine learning exactly offers what is desperately needed in intelligent adaptive behavior. But when trying to adapt by learning, one will sooner or later encounter one or more well--known problems, some of which have been discussed in [Webb, 2001]. We propose a framework for describing user modeling problems, identify several reasons for inherent noise and discuss few promising approaches which tackle these problems.
