A unified view of performance metrics: translating threshold choice into expected classification loss

José Hernández-Orallo; Flach, Peter; Ferri Ramírez, César (Microtome Publishing, 2012)

[EN] Many performance metrics have been introduced in the literature for the evaluation of classification performance, each of them with different origins and areas of application. These metrics include accuracy, unweighted ...
Analysis of diesel spray atomization by means of a near-nozzle field visualization technique

Payri Marín, Raúl; Salvador Rubio, Francisco Javier; Gimeno García, Jaime; De La Morena Borja, Joaquín (Begell House, 2011)

[EN] In this paper, a high-resolution visualization technique has been used in order to characterize Diesel spray structure in the near-nozzle field. For this purpose, three conical nozzles with different diameters have ...
Energetic evaluation of an internal heat exchanger in a CO2 transcritical refrigeration plant using experimental data

Torrella Alcaraz, Enrique; Sanchez, D.; Llopis, R.; Cabello, R. (ELSEVIER SCI LTD, 2011)

[EN] The performance of an Internal Heat Exchanger (IHX) operating in a CO 2 transcritical refrigeration plant is analysed, from an energetic point of view, in this work. The evaluation is based on experimental data by ...
Influence of operating conditions on ceramic ultrafiltration membrane performance when treating textile effluents

Barredo Damas, Sergio; Alcaina Miranda, María Isabel; GEMMA, MATTEO; Iborra Clar, María Isabel; Mendoza Roca, José Antonio (IWA Publishing, 2011)

[EN] This work studies the performance of three commercial ceramic ultrafiltration membranes (ZrO 2-TiO 2) treating raw effluent from a textile industry. The effect of crossflow velocity at 3, 4 and 5 m s -1 as well as ...
Oil type influence on the optimal charge and performance of a propane chiller

Martínez Galván, Israel; Gonzálvez-Maciá, José; Corberán, José M.; Royo, Rafael (Elsevier, 2011)

[EN] The paper presents the experimental results of a charge optimization study of a water-to-water chiller with two different oils: Mineral and POE. The employed chiller is a prototype which works with propane as refrigerant ...
Quality assurance applied to digital radiographic equipment by developed software for phantom images

Mayo Nogueira, Patricia; Ródenas Escribá, Francisco de Asís; Campayo, J. M.; Marin, B.; Verdú Martín, Gumersindo Jesús (American Nuclear Society, 2011)

[EN] The assessment and control of image quality is a fundamental task associated with good practice to guarantee a suitable diagnosis by the radiologist. The need for image quality assessments in radiography is well ...
ROC curves for regression

Hernández-Orallo, José (Elsevier, 2013-12)

Receiver Operating Characteristic (ROC) analysis is one of the most popular tools for the visual assessment and understanding of classifier performance. In this paper we present a new representation of regression models ...
ROC curves in cost space

Hernández Orallo, José; Flach ., Peter; Ferri Ramírez, César (Springer Verlag (Germany), 2013-10)

ROC curves and cost curves are two popular ways of visualising classifier performance, finding appropriate thresholds according to the operating condition, and deriving useful aggregated measures such as the area under the ...
Setting decision thresholds when operating conditions are uncertain

Ferri Ramírez, César; Hernández-Orallo, José; Flach, Peter (Springer-Verlag, 2019-07)

[EN] The quality of the decisions made by a machine learning model depends on the data and the operating conditions during deployment. Often, operating conditions such as class distribution and misclassification costs have ...
Transient tracking of low and high-order eccentricity-related components in induction motors via TFD tools

Climente Alarcón, Vicente; Antonino-Daviu, J.; Riera-Guasp, Martín; Pons Llinares, Joan; Roger-Folch, José; Jover-Rodriguez, P.; Arkkio, A. (Elsevier, 2011)

[EN] The present work is focused on the diagnosis of mixed eccentricity faults in induction motors via the study of currents demanded by the machine. Unlike traditional methods, based on the analysis of stationary currents ...
