A Shape Comparison Reinforcement Method Based on Feature Extractors and F1-Score
2019 IEEE International Conference on Systems, Man and Cybernetics (SMC), 2019Evaluating object segmentation is a topic of great interest for shape comparison techniques. In this work, ad-hoc metrics for a detailed segmentation analysis and a novel keypoint based method for comparing pairs of shapes are presented. As references, two different segmentation approaches were used: a handmade segmentation and an automatic one based ...

Maximum F1-Score Discriminative Training Criterion for Automatic Mispronunciation Detection
IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2015We carry out an in-depth investigation on a newly proposed Maximum F1-score Criterion (MFC) discriminative training objective function for Goodness of Pronunciation (GOP) based automatic mispronunciation detection that makes use of Gaussian Mixture Model-hidden Markov model (GMM-HMM) as acoustic models. The formulation of MFC seeks to directly optimize

F1 Score Assesment of Gaussian Mixture Background Subtraction Algorithms Using the MuHAVi Dataset
6th International Conference on Imaging for Crime Prevention and Detection (ICDP-15), 2015Background subtraction algorithms are mainly used to segment some specific moving objects in an image sequences. Within of the action recognition context, these methods may be proper to generate automatically silhouettes of the human actions. In this way, MuHAVi is a human action dataset which provides a small set of manually annotated silhouettes and ...

An intruder from another world: F1-score.
Revista Electrónica AnestesiaREl F1-score, también llamado F-score o medida F, es un estimador de la capacidad de clasificación de una prueba que se usa con frecuencia en la ciencia de datos y en los algoritmos de inteligencia artificial y que puede ser de utilidad para la valoración de las pruebas diagnósticas.
