Author: Rafael G. Mantovani, Edesio Alcobaça, André L. D. Rossi, Joaquin Vanschoren, André C. P. L. F. de Carvalho Source: "A meta-learning recommender system for hyperparameter tuning: predicting when tuning improves SVM classifiers" - Information Sciences, volume 501, 2019. Please cite: 10.1016/j.ins.2019.06.005 This is a meta-dataset which describes the SVM hyperparameter tuning problem. The target attribute indicates whether tuning is required or default hyperparameter values are enough to each dataset (row). Targets were defined using a statistical labelling rule comparing the predictive performance of models induced with defaults values and tuned ones. In this version of the dataset, the labelling rule was set with 99% confidence.
