Abstract

CORRALES, David Camilo et al. Early warning system for coffee rust disease based on error correcting output codes: a proposalSistema de alerta temprana para la roya en el café basado en códigos de salida de corrección de error: una propuesta. Rev. ing. univ. Medellín [online]. 2014, vol.13, n.25, pp.57-64. ISSN 1692-3324.

Colombian coffee producers have had to face the severe consequences of the coffee rust disease since it was first reported in the country in 1983. Recently, machine learning researchers have tried to predict infection through classifiers such as decision trees, regression Support Vector Machines (SVM), non-deterministic classifiers and Bayesian Networks, but it has been theoretically and empirically demonstrated that combining multiple classifiers can substantially improve the classification performance of the constituent members. An Early Warning System (EWS) for coffee rust disease was therefore proposed based on Error Correcting Output Codes (ECOC) and SVM to compute the binary functions of Plant Density, Shadow Level, Soil Acidity, Last Nighttime Rainfall Intensity and Last Days Relative Humidity.

Keywords : Coffee Rust Disease; Early Warning System; ECOC; SVM; Codeword.
