چکیده
This paper describes a system for the Multiple Fundamental Frequency Estimation and Tracking task in MIREX (Music Information Retrieval Evaluation eXchange) 2009. The method is a modification of Harmonic Temporal Structured Clustering(HTC), which is a kind of constrained Gaussian Mixture Model estimation using EM algorithm. In the modification one term of a function of model power is added to objective function to fit input power spectrogram with possible fewest Gaussian kernels.We submitted this system to the same task in MIREX 2007.

Bayesian Nonnegative Harmonic-Temporal Factorization and Its Application to Multipitch Analysis
Since important musical features are mutually dependent, their relations should be analyzed simultaneously. Their Bayesian analysis is particularly important to reveal their statistical relation. As the first step for a unified music content analyzer, we focus on the harmonic and temporal structures of the wavelet spectrogram obtained from harmonic sounds. In this paper, we present a new Bayesi...

متن کاملUnsupervised Classification Techniques for Multipitch Estimation
In this paper, we present a fast and efficient technique for multipitch estimation of musical signals. We deal with mixtures where several instruments are present in a monophonic recording. The approach consists in clustering the spectral peaks of the mixture to obtain a spectral representation of each musical note. These spectra are then used to estimate the fundamental frequencies. We compare...
متن کاملHigh-Dimensional Unsupervised Active Learning Method
In this work, a hierarchical ensemble of projected clustering algorithm for high-dimensional data is proposed. The basic concept of the algorithm is based on the active learning method (ALM) which is a fuzzy learning scheme, inspired by some behavioral features of human brain functionality. High-dimensional unsupervised active learning method (HUALM) is a clustering algorithm which blurs the da...
