Improving User-Interface of Interactive EC for Composition-Aid by means of Shopping Basket Procedure

The use of Interactive Evolutionary Computation(IEC) issuitable to the development of art-creation aid system forbeginners. This is because of important features of IEC,like the ability of optimizing with ambiguous evaluationmeasures, and not requiring special knowledge about artcreation. With the popularity of Consumer Generated Media, many beginners in term of art-creation are interestedin creating their own original art works. Thus developing ofuseful IEC system for musical creation is an urgent task.However, user-assist functions for IEC proposed in pastworks decrease the possibility of getting good unexpectedresults, which is an important feature of art-creation withIEC. In this paper, The , , author proposes a new IEC evaluation process named "Shopping Basket" procedure IEC.In the procedure, an user-assist function called SimilarityBased Reasoning allows for natural evaluation by the user.The function reduces user's burden without reducing thepossibility of unexpected results. The , , author performs anexperiment where subjects use the new interface to validateit. As a result of the experiment, the , , author concludes thethe new interface is better to motivate users to composewith IEC system than the old interface.
