A data set with 1000 rows is input to a neural network in Weka. The test option is set to 10-fold cross validation and the neural network option validationSetSize = 20%. How many rows of data are used in a validation set in a fold?
A support vector machine in Weka uses a Gaussian (radial basis function) kernel with parameter gamma. Gamma should be selected less than or equal to one. Circle True or False.
A support vector machine in Weka uses a Gaussian (radial basis function) kernel with parameter gamma = 0.2. This corresponds to the parameter σ2 equal to what value?
