A comparison of machine learning models for the detection of metastatic tissue in axillary lymph nodes

Abad Martínez, Javier (Universitat Politècnica de València, 2020-07-30)

[EN] Breast cancer is currently the leading cause of death due to cancer in women, after lung cancer. For its diagnosis and staging, detection of metastatic tissue in axillary lymph nodes is occasionally used, since lymphatic ...
A Comparison of Nonparametric Methods in the Graduation of Mortality: Application to Data from the Valencia Region (Spain)

Debón Aucejo, Ana María; Montes-Suay, Francisco; Sala-Garrido, Ramón (Blackwell Publishing, 2006-08)

[EN] The nonparametric graduation of mortality data aims to estimate death rates by carrying out a smoothing of the crude rates obtained directly from original data. The main difference with regard to parametric models is ...
A comparison of parametric models for mortality graduation. Application to mortality data of the Valencia Region

Debón Aucejo, Ana María; Montes-Suay, Francisco; Sala-Garrido, Ramon (Institut d'Estadística de Catalunya (Idescat), 2005-12)

[EN] The parametric graduation of mortality data has as its objective the satisfactory estimation of the death rates based on mortality data but using an age-dependent function whose parameters are adjusted from the crude ...
A comprehensive review and evaluation of permutation flowshop heuristics to minimize flowtime

Pan, Quan-Ke; Ruiz García, Rubén (Elsevier, 2013-01)

[EN] In recent years, a large number of heuristics have been proposed for the minimization of the total or mean flowtime/completion time of the well-known permutation flowshop scheduling problem. Although some literature ...
A constraint programming approach for the premarshalling problem
