Fuzzy inferencing is suitable for solving real world problems:
operating with fuzzy and non-complete data.
Adaptive systems development needs application of machine
learning techniques.
AI research focused to solving specific and particular
problems,
SE distrust black-box approach and complexity of AI methods
Way to go:


AI: need to elevate abstraction level of solutions from a
particular problem to a strategy that solves a class of
problems
SE: It is not enough to embed AI method; integration of AI
methods in SE processes and techniques
