This paper investigates the rhythmic organization of Mandarin utterances through both corpus analyses and experimental studies. We propose to add a new prosodic unit, the principle prosodic unit (PPU), into the prosodic hierarchy of Mandarin utterances. The key characteristic of PPU is that innerunit words normally have to be spoken closely, while inter-unit grouping is rather flexible. Because...

We present an algorithm for local word grouping to extricate fixed word order dependencies in Hindi sentences. Local word grouping is achieved by defining regular expressions for the word groups. Ambiguities occurring during word grouping are also resolved. Hindi being a free order language, fixed order word group extraction is essential for decreasing the load on the free word order parser. Th...

Perceptual grouping is well known to be a fundamental process during visual perception, notably grouping across scenic regions that do not receive contrastive visual inputs. Illusory contours are a classical example of such groupings. Recent psychophysical and neurophysiological evidence have shown that the grouping process can facilitate rapid synchronization of the cells that are bound togeth...

In this paper, we propose a real-time method for accurate salient closed boundary tracking via a combination of shape constraints and perceptual grouping on edge fragments. Particularly, we encode the Gestalt law of proximity and the prior shape constraint in a novel ratio-form grouping cost. The proximity and prior constraint are depicted by the relative gap length and average distance differe...

The paper deals with a development of the rolling horizon approach introduced recently for grouping maintenance strategies of multi-component systems by integrating two efficient optimization algorithms. The proposed approach can help to construct an optimal maintenance planning with a given availability constraint under limited repairmen. Thanks to the rolling horizon spirit, the maintenance p...

This paper tries to discuss the interrelation between prosody and syntax by clarifying some syntactic constraints in Chinese prosodic segmentation and grouping. The main attention will be paid to search for (1) possible correlation between prosodic breaks and syntactic construction; (2) possible correlation between prosodic breaks and POS; and (3) the role of syntactic and lexical information i...

Background in music psychology and music computation. In Lerdahl and Jackendoff’s Generative Theory of Tonal Music (1983), the authors try to formalize cognitive processes seen in music, referring to Chomskyan (generative) linguistics. Among other processes found in musical cognition (such as harmonic tension and detecting rhythmic patterns), Lerdahl and Jackendoff describe the process of group...

Constrained estimators that enforce variable selection and grouping of highly correlated data have been shown to be successful in finding sparse representations and obtaining good performance in prediction. We consider polytopes as a general class of compact and convex constraint regions. Well established procedures like LASSO (Tibshirani, 1996) or OSCAR (Bondell and Reich, 2008) are shown to b...
