Despite massive research efforts, the molecular etiology of bovine polledness and the developmental pathways involved in horn ontogenesis are still poorly understood. In a recent article, we provided evidence for the existence of at least two different alleles at the Polled locus and identified candidate mutations for each of them. None of these mutations(More)
We address the issue of generating texts in the style of an existing author, that also satisfy structural constraints imposed by the genre of the text. We focus on song lyrics, for which structural constraints are well-defined: rhyme and meter. Although Markov processes are known to be suitable for representing style, they are difficult to control in order(More)
Advances in networking and transmission of digital multimedia data bring huge catalogues of multimedia items to users. In the case of music, accessing these catalogues raises a problem for users and content providers, which we define as the music selection problem. From the user point of view, the goals are to match preferences, as well as provide them with(More)
This paper addresses the problem of automatically extracting perceptive information from acoustic signals, in a supervised classification context. Global labels, i.e., atomic information describing a music title in its entirety, such as its genre, mood, main instruments, or type of vocals, are entered by humans. Classifiers are trained to map audio features(More)
We discuss the problem of the representation of constraints in an object-oriented programming language. We focus on a particular topic constraint satisfaction for finite domains and propose a class library that integrates constraints within an object-oriented language. The library is based on the systematic reification of variables, constraints, problems(More)
Advances in networking and transmission of digital multimedia data will bring soon huge catalogues of music to users. Accessing these catalogues raises a problem for users and content providers, that we define as the music selection problem. We introduce three main goals to be satisfied in music selection: match user preferences, provide users with new(More)
Markov chains are a well known tool to model temporal properties of many phenomena, from text structure to fluctuations in economics. Because they are easy to generate, Markovian sequences, i.e. temporal sequences having the Markov property, are also used for content generation applications such as text or music generation that imitate a given style.(More)
Many works in audio and image signal analysis are based on the use of “features” to represent characteristics of sounds or images. Features are used in various ways, for instance as inputs to classifiers to categorize automatically objects, e.g. for audio scene description. Most, if not all, approaches focus on the development of clever classifiers and on(More)
