Keyphrases are widely used as a brief summary of documents. Since manual assignment is time-consuming, various unsupervised ranking methods based on importance scores are proposed for keyphrase extraction. In practice, the keyphrases of a document should not only be statistically important in the document, but also have a good coverage of the document. Based on this observation, we propose an u...

This paper presents an exemplar-based method to provide intuitive way for users to generate 3D human body shape from semantic parameters. In our approach, human models and their semantic parameters are correlated as a single linear system of equations. When users input a new set of semantic parameters, a new 3D human body will be synthesized from the exemplar human bodies in the database. This ...

-Inpainting is the process of reconstructing lost or deteriorated part of images based on the background information. i. e .it fills the missing or damaged region in an image utilizing spatial information of its neighboring region. Inpainting algorithm have numerous applications. It is helpfully used for restoration of old films and object removal in digital photographs. The main goal of the al...

Even speakers of American English who think they grew up in the Midwest do not agree on its boundaries. So what determines the meaning of 'Midwest' to a given speaker? We argue that the meaning of a geographical term like ‘Midwest’ is based in part on one's experience with locations that one knows to be part of the region. This exemplar-based knowledge causes the perceived location of the Midwe...

In this paper we extend the concept of exception spaces as defined by Cost and Salzberg (Cost and Salzberg, 1993), in the context of exemplar-based reasoning. Cost et al. defined exception spaces based on the goodness, in terms of performance, of an exemplar. While this is straightforward when using exemplars for classification problems, such a definition does not exist for regression problems....

A dynamical model of phonetic detail is presented. The model is compared to an exemplar-based model, which has been shown to offer an account of (presumed) frequency-dependent lenition processes. The dynamical model accounts for the same lenition patterns. However, there is a key difference. In contrast to the exemplar model, the dynamical model provides a handle on the timecourse of assembling...
