Let us try to code this optimization problem. The dataset is here n = length(myocarde[,"PRONO"]) myocarde0 = myocarde myocarde0$PRONO = myocarde$PRONO*2-1 C = .5 and we have to set a value for the cost CC. In the (linearly) constrained optimization function in R, we need ...

Load the data, then change the labels from 0 and 1 to -1 and 1. Use the StandardScaler to normalize the data, this is almost always recommended for SVM. Finally, initialize the LinearSVMUsingSoftMargin class and invoke the fit() function. The code for plot_decision_boundary() f...

s the state-of-the-art on six text classification tasks, reducing the error by 18-24% on the majority of datasets. Furthermore, with only 100 labeled examples, it matches the performance of training from scratch on 100 times more data. We open-source our pretrained models and code....
