Globally Optimal Audio Partitioning

چکیده
We present a technique for partitioning an audio file into maximally-sized segments having nearly uniform spectral content, ideally corresponding to notes or chords. Our method uses dynamic programming to globally optimize a measure of simplicity or homogeneity of the intervals in the partition. Here we have focused on an entropy-like measure, though there is considerable flexibility in choosing this measure. Experiments are presented for several musical scenarios. 1

Globally Optimal Image Partitioning by Multicuts
We introduce an approach to both image labeling and unsupervised image partitioning as different instances of the multicut problem, together with an algorithm returning globally optimal solutions. For image labeling, the approach provides a valid alternative. For unsupervised image partitioning, the approach outperforms state-of-the-art labeling methods with respect to both optimality and runti...
متن کاملStudy of the Circuit Partitioning Using Genetic Algorithm
This paper discusses the various circuit partitioning problems. Circuit partitioning is a well known NP hard problem. The algorithms can partition circuit into number of sub-circuits. Different design styles of circuits have different objectives for the partitioning. Genetic algorithm for circuit partitioning is discussed in this paper. The objective of the Genetic Algorithm is to find an optim...
متن کاملHigh Quality Scalable Stereo Audio Coding
This paper proposes an efficient, low complexity, scalable audio coder based on a combination of two embedded coding algorithms: the SPIHT (set partitioning in hierarchical trees) coding algorithm [1] and an embedded, nested binary set partitioning (NBSP) algorithm. The SPIHT algorithm, considered to be the premier state-of-the-art algorithm in still image compression, is used for the low frequ...
متن کاملGlobally Optimizing Graph Partitioning Problems Using Message Passing
Graph partitioning algorithms play a central role in data analysis and machine learning. Most useful graph partitioning criteria correspond to optimizing a ratio between the cut and the size of the partitions, this ratio leads to an NP-hard problem that is only solved approximately. This makes it difficult to know whether failures of the algorithm are due to failures of the optimization or to t...
متن کاملRecursive Partitioning for Personalization using Observational Data
We study the problem of learning to choose from m discrete treatment options (e.g., news item or medical drug) the one with best causal effect for a particular instance (e.g., user or patient) where the training data consists of passive observations of covariates, treatment, and the outcome of the treatment. The standard approach to this problem is regress and compare: split the training data b...
