In most cases, people judge creativity by evaluating the resulting artifact, after the productive behavior has been completed. Hence, we will concentrate on the artifact here. However, sometimes the artistic process is inferable by the evaluator, perhaps due to some attributes of the artifact, or sometimes it’s even observable. Colton (2008) argues that art is identified as more creative if the...

Delta-oriented programming (DOP) is a modular approach for implementing software product lines. Delta modules generalize feature modules by allowing removal of functionality. However, DOP requires to select one particular product as core product from which all products are generated. In this paper, we propose pure deltaoriented programming (Pure DOP) that is a conceptual simplification of tradi...

Several program transformations|magic sets, envelopes, NRSU transformations and context transformations, among others|have been proposed for eeciently computing the answers to a query while taking advantage of the query constants. These transformations use sideways information passing strategies (sips) to restrict bottom-up evaluation to facts potentially relevant to the query. It is of interes...

We present a new method for score-informedsource separation, combining ideas from twoprevious approaches: one based on paramet-ric modeling of the score which constrains theNMF updating process, the other based onPLCA that uses synthesized scores as priorprobability distributions. We experimentallyshow improved separation results using theBSS EVAL and PEASS toolk...

We demonstrate how a new data structure for sparse distributed polynomials in the Maple kernel significantly accelerates several key Maple library routines. The POLY data structure and its associated kernel operations (degree, coeff, subs, has, diff, eval, ...) are programmed for high scalability with very low overhead. This enables polynomial to have tens of millions of terms, increases parall...
