It has been argued that the relative position of spectral envelopes along frequency axis serves as a cue for musical instrument size (e.g., violin vs viola) and shape envelope encodes family identity (violin flute). is further known fundamental (F0), F0-register specific instruments, dynamic level strongly affect properties acoustical sounds. However, associations between these factors have not...

This paper outlines a testing procedure for assessing the relative out-of-sample predictive accuracy of multiple conditional distribution models, and surveys existing related methods in the area of predictive density evaluation, including methods based on the probability integral transform and the Kullback-Leibler Information Criterion. The procedure is closely related to Andrews’ (1997) condit...

Extended Abstract. Suppose n i.i.d. observations, X1, …, Xn, are available from the unknown distribution F(.), goodness-of-fit tests refer to tests such as H0 : F(x) = F0(x) against H1 : F(x) $neq$ F0(x). Some nonparametric tests such as the Kolmogorov--Smirnov test, the Cramer-Von Mises test, the Anderson-Darling test and the Watson test have been suggested by comparing empirical ...

Let F0 be a fixed k-uniform hypergraph. The problem of finding the integer F0-packing number νF0 (H) of a k-uniform hypergraph H is an NP-hard problem. Finding the fractional F0-packing number ν∗ F0 (H) however can be done in polynomial time. In this paper we give a lower bound for the integer F0-packing number νF0 (H) in terms of ν∗ F0 (H) and show that νF0 (H) ≥ ν∗ F0 (H)− o(|V (H)| k).

We study the effects of modeling tone in Mandarin speech recognition. Including the neutral tone, there are 5 tones in Mandarin and these tones are syllable-level phenomena. A direct acoustic manifestation of tone is the fundamental frequency (f0). We will report on the effect of f0 on the acoustic recognition accuracy of a Mandarin recognizer. In particular, we put f0, its first derivative (f0...

Based on the measurements of (D+ s ,D +) → f0(1370)π we determine, in a model independent way, the allowed ss̄ content in the scalar meson f0(1370). We find that, on the one hand, if this isoscalar resonance is a pure nn̄ state [nn̄ ≡ (uū + dd̄)/ √ 2 ], a very large W -annihilation term will be needed to accommodate D+ s → f0(1370)π. On the other hand, the ss̄ component of f0(1370) should be small e...
