In 1989, composer and researcher Jean-Claude Risset's series of interactive sketches for piano and Disklavier entitled Duet for One Pianist explored the performative possibilities made available to pianists through the augmentation of emotive human musical gesture with the precise reactive and computational capabilities afforded by computer-based musical systems. As computer and musical softwar...

We present a system to perform sound source separation of an arbitrary number of speech or music sources from a stereo signal. We build on the work of other authors’ DUET system, which uses a histogram technique to estimate the mixing parameters of the time-frequency sparse sources, before using a nearest-neighbor approach to demix the sources. Herein, we describe a new demixing method called D...

Sparse Component Analysis is a relatively young technique that relies upon a representation of signal occupying only a small part of a larger space. Mixtures of sparse components are disjoint in that space. As a particular application of sparsity of speech signals, we investigate the DUET blind source separation algorithm in the context of speech recognition for multiparty recordings. We show h...

Despite the recent advances in planning for classical domains, the question of how to use domain knowledge in planning is yet to be completely and clearly answered. Some of the existing planners use domain-independent search heuristics, and some others depend on intensively-engineered domainspecific knowledge to guide the planning process. In this paper, we describe an approach to combine ideas...
