Estimating the Error Distribution of a Single Tap Sequence without Ground Truth

Roger B Dannenberg, Larry Wasserman
Thus, without knowledge of true beat times, and without even requiring the existence of precise beat times, we can estimate the uncertainty of tap times.  ...  Multiple independent taps can be used to estimate not only the location of the true beat time, but also the statistical distribution of measured tap times around the true beat time.  ...  ACKNOWLEDGEMENTS The authors would like to acknowledge the contributions of Nathaniel Anozie to the initial exploration and analysis of this data, and Cosma Shalizi for helpful consultation and discussions  ...

When did the train arrive? A Bayesian approach to enrich timetable information using smart card data

Philip Lemaitre, Michael Riis Andersen, Jes Frellsen
2021 IEEE Open Journal of Intelligent Transportation Systems  
The method uses the knowledge of how the tap-outs are distributed in a hierarchical, latent Bayesian model to predict the arrival times of trains.  ...  This paper shows how the uncertainty of arrival and departure times affects passengers to train assignments and proposes a method for estimating the missing arrival time of trains when the recorded timetable  ...  A/S.  ...

Towards Automatically Correcting Tapped Beat Annotations for Music Recordings

Jonathan Driedger, Hendrik Schreiber, Bas De Haas, Meinard Müller
2019 Zenodo  
Second, we introduce a novel visualization method that serves as a tool to analyze the results of the correction procedure for potential errors.  ...  In this work we aim to automate this correction step by "snapping" the taps to close-by audio cues - a strategy that is often used by beat tracking algorithms to refine their beat estimates.  ...  Furthermore, we thank Jeroen Bransen for the discussions about the algorithmic details of the procedure, Jeffrey van Rossum for creating the original taps for the recordings in the dataset, as well our  ...

Selective Sampling for Beat Tracking Evaluation

André Holzapfel, Matthew E. P. Davies, José R. Zapata, João Lobato Oliveira, Fabien Gouyon
2012 IEEE Transactions on Audio, Speech, and Language Processing  
In this paper, we propose a method that can identify challenging music samples for beat tracking without ground truth.  ...  Our method, motivated by the machine learning method "selective sampling", is based on the measurement of mutual agreement between beat sequences.  ...  ACKNOWLEDGEMENTS We thank the authors of the beat tracking algorithms for making their code available.  ...

A Hybrid Graphical Model For Aligning Polyphonic Audio With Musical Scores

Christopher Raphael
2004 Zenodo  
For each of these examples we created ground truth by playing the audio file from the computer and tapping along on the keyboard while recording the times of each key press.  ...  In interpreting these results, one should keep in mind that the tapping ground truth is not especially accurate, thereby making the measured performance of the algorithm appear worse than they are in truth  ...

Towards a Class-Based Representation of Perceptual Tempo for Music Retrieval

Ching-Wei Chen, Kyogu Lee, Ho-Hsiang Wu
2009 2009 International Conference on Machine Learning and Applications  
Tempo is a common criterion by which humans describe and categorize music, and this has spawned a large amount of research in the field of automatic tempo estimation.  ...  In this paper, the problem of tempo estimation is presented as a statistical classification problem.  ...  The ground truth tempo was given as a single BPM value, derived from the ``foot-tapping rate'' of the annotator, and was intended to represent the most salient tempo within the music, as perceived by a  ...

2017 arXiv   pre-print
Given a video segment containing an object interaction, we model the probability for a verb, out of a list of possible verbs, to be used to annotate that interaction.  ...  The proba- bility is learnt from crowdsourced annotations, and is tested on two public datasets, comprising 1405 video sequences for which we provide annotations on 90 verbs.  ...  Error of Predicted Verb Probabilities has been able to fit well to the ground truth.  ...
