Riassunto: La necessità di definire una misura di distanza tra Regole di Associazione, al fine di cogliere l’evoluzione temporale del fenomeno indagato, è di primaria importanza quando si dispone di basi di dati riferiti alle stesse variabili ma osservate in momenti di tempo successivi. L’obiettivo è quello di separare la naturale variabilità di un fenomeno nel tempo, da variazioni sistematiche...

We find a quantum mechanical formulation of proper time for spin 1/2 particles within the framework of the Dirac theory. It is shown that the rate of proper time can be represented by an operator called the “tempo operator”, and that the proper time itself be given by the integral of the expectation value of the operator. The tempo operator has some terms involving the Pauli spin matrices, and ...

In the study, we propose a method to select components from datasets to form two kinds of categorizes {reqProcessing, noProcessing} for tempogram selector, which is built from a classifier. The research utilizes the low pass filtering (LPF) as the processing, so there are two tempogram with LPF or without LPF. The trained classifier is used to select the best out of the tempograms, which repres...

Automatic beat tracking is challenging task, especially for audio music with time-varying meters. This study proposes a dynamic programming approach with positional weighting window to handle beat tracking with time-varying meters. In particular, the tempo curve is the reference to obtain correct beat positions. The weighting window is used to adapt bandwidth of tempo which reciprocal represent...

In this paper we present preliminary work examining the relationship between the formation of expectations and the realization of musical performances, paying particular attention to expressive tempo and dynamics. To compute features that reflect what a listener is expecting to hear, we employ a computational model of auditory expectation called the Information Dynamics of Music model (IDyOM). ...

The present study shows how the dynamics of output speech rate can be attributed to systematic contributions from layers of discourse units as well as phonological timing. Quantitative analysis of three modes of Mandarin continuous speech reveals tempo cadence by discourse units, thus demonstrating multiple layers of discourse tempo and boundary lengthening contribute to modulations of output s...

We examined the relative stability of pitch, tempo, and rhythm in maternal speech and singing to prelinguistic infants. Mothers were recorded speaking and singing to their infants on two occasions separated by 1 week or more. The pitch level and tempo of identical utterances were highly variable across the 1-week period, but these features were virtually unchanged in song repetitions. Rhythmic ...

This paper presents an application of Empirical Mode Decomposition (EMD) on the induction of notated tempo from music recordings. At a first stage, EMD is employed as a means to segment music recordings into segments that exhibit similar rhythmic characteristics. At a second stage, EMD is used in order to analyze the diagonals of the Self-Similarity Matrix of each segment, so as to estimate the...

In an expressive performance, a skilled musician shapes the music by continuously modulating aspects like tempo and loudness to communicate high level information such as musical structure and emotion. Although automatic modelling of this phenomenon remains beyond the current state of the art, we present a system that is able to measure tempo and dynamics of a musical performance and to track t...

Tempo perception has been studied using many different methodologies in trying to isolate the motion patterns of a conductor in experimental stimuli. In doing so, the context of conducting has been ignored including secondary bodily motion, expression and communication from the conductor, and conducting gestures outside of the realm of tempo control. The aim of this study is to test the ability...
