This paper describes a system for the Multiple Fundamental Frequency (F0) Estimation and Tracking task in MIREX (Music Information Retrieval Evaluation eXchange) 2008. The system is based on modeling energy distribution of a sound source on the time-frequency plane (frequency domain is log-frequency axis) and estimates F0's through representing the(More)
A lot of research has been done into automatically eliciting service specifications of a system, whose specification is unknown, by analyzing output signals corresponding to input signals. This paper proposes algorithms for automatically eliciting state transition diagrams based on an enhanced state transition model from a set of rules that represent(More)
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 Struc-tured Clustering(HTC), which is a kind of constrained Gaus-sian Mixture Model estimation using EM algorithm. In the modification one term of(More)
