Information Theoretic Measures for Clusterings Comparison: Variants, Properties, Normalization and Correction for Chance
TL;DR: An organized study of information theoretic measures for clustering comparison, including several existing popular measures in the literature, as well as some newly proposed ones, and advocates the normalized information distance (NID) as a general measure of choice.
Journal ArticleDOI
The Geneva Minimalistic Acoustic Parameter Set (GeMAPS) for Voice Research and Affective Computing
Florian Eyben,Klaus R. Scherer,Björn Schuller,Johan Sundberg,Elisabeth André,Carlos Busso,Laurence Devillers,Julien Epps,Petri Laukka,Shrikanth S. Narayanan,Khiet P. Truong +10 more
TL;DR: A basic standard acoustic parameter set for various areas of automatic voice analysis, such as paralinguistic or clinical speech analysis, is proposed and intended to provide a common baseline for evaluation of future research and eliminate differences caused by varying parameter sets or even different implementations of the same parameters.
Proceedings ArticleDOI
Information theoretic measures for clusterings comparison: is a correction for chance necessary?
TL;DR: This paper derives the analytical formula for the expected mutual information value between a pair of clusterings, and proposes the adjusted version for several popular information theoretic based measures.
Journal ArticleDOI
A review of depression and suicide risk assessment using speech analysis
Nicholas Cummins,Stefan Scherer,Jarek Krajewski,Sebastian Schnieder,Julien Epps,Thomas F. Quatieri +5 more
TL;DR: How common paralinguistic speech characteristics are affected by depression and suicidality and the application of this information in classification and prediction systems is reviewed.
Journal ArticleDOI
Signal Processing in Sequence Analysis: Advances in Eukaryotic Gene Prediction
TL;DR: A new technique for the recognition of acceptor splice sites is proposed, which combines signal processing-based gene and exon prediction methods with an existing data-driven statistical method, and reveals a consistent reduction in false positives at different levels of sensitivity.
