Approximate reasoning algorithm of interval-valued fuzzy sets based on least square method ?
In this paper, we develop a new method for bidirectional approximate reasoning of interval-valued fuzzy sets by employing least squares method and investigate some properties for our proposed approximate reasoning method. Furthermore, we use four numerical examples to illustrate our proposed method reasonable.
