Resource location in structured P2P system has a critical influence on the system performance. Existing analytical studies of Chord protocol have shown some potential improvements in performance. In this paper a splay tree-based new Chord structure called SChord is proposed to improve the efficiency of locating resources. We consider a novel implementation of the Chord finger table (routing tab...

We improve upon our simple approach for learning the “associational meaning” of chord sequences from lyrics based on contingency statistics induced over a set of lyrics with chord annotations. Specifically, we refine this process by using word alignment tools developed for statistical machine translation, and we also use a much larger set of chord annotations. In addition, objective evaluation ...

In this paper, we propose a variant of Chord system that is resilient to routing attacks. By routing attacks, we mean the attacks which detour the looking up messages, aiming to disrupt the performance of data look-up systems by increasing the path length of queries. Chord routes messages uni-directionally and has no bi-directional edges. While its performance in the absence of routing attacks ...

Key information is a useful information for tonal music analysis. It is related to chord progressions, which follows some specific structures and rules. In this paper, we describe a generative account of chord progression consisting of phrase-structure grammar rules proposed by Martin Rohrmeier. With some modifications, these rules can be used to partition a chord symbol sequence into different...

We present a genre classification framework for audio music based on a symbolic classification system. Audio signals are transformed to a symbolic representation of harmony using a chord transcription algorithm, by computing Harmonic Pitch Class Profiles. Then, language models built from a groundtruth of chord progressions for each genre are used to perform classification. We show that chord pr...

We study fundamental morphological descriptors of disordered media (e.g., heterogeneous materials, liquids, and amorphous solids): the chord-length distribution function p(z) and the free-path distribution function p(z,a). For concreteness, we will speak in the language of heterogeneous materials composed of two different materials or “phases.” The probability density function p(z) describes th...
