Unsupervised Melody Segmentation Based on a Nested Pitman-Yor Language Model

Gregorian melody, modality, and memory: Segmenting chant with Bayesian nonparametrics

The idea that Gregorian melodies are constructed from some vocabulary of segments has long been a part of chant scholarship. This so-called "centonisation" theory has received much musicological criticism, but frequent r…

Unsupervised learning of agglutinated morphology using nested Pitman-Yor process based morpheme induction algorithm

Unsupervised Segmentation of Phoneme Sequences based on Pitman-Yor Semi-Markov Model using Phoneme Length Context

Unsupervised segmentation of phoneme sequences is an essential process to obtain unknown words during spoken dialogues. In this segmentation, an input phoneme sequence without delimiters is converted into segmented sub-s…

Une m\'ethode non-supervis\'ee pour la segmentation morphologique et l'apprentissage de morphotactique \`a l'aide de processus de Pitman-Yor (An unsupervised method for joint morphological segmentation and morphotactics learning using Pitman-Yor processes)

Cet article pr{\'e}sente un mod{\`e}le bay{\'e}sien non-param{\'e}trique pour la segmentation morphologique non supervis{\'e}e. Ce mod{\`e}le semi-markovien s{'}appuie sur des classes latentes de morph{\`e}mes afin de mo…

Shared Segmentation of Natural Scenes Using Dependent Pitman-Yor Processes

We develop a statistical framework for the simultaneous, unsupervised segmentation and discovery of visual object categories from image databases. Examining a large set of manually segmented scenes, we use chi--square te…
