The problem of aggregating multiple numerical criteria to form overall objective functions is of considerable importance in many disciplines. The ordered weighted averaging (OWA) a...
Abstract. We extend different Description Logics by concrete domains (such as integers and reals) and by aggregation functions over these domains (such as min;max;count;sum), which...
We present a coherent framework for data clustering. Starting with a Hopfield network, we show the solutions for several well-motivated clustering objective functions are principa...
