This guide is the second part of three guides about Support Vector Machines (SVMs). In this guide, we will keep working on the forged bank notes use case, understand what SVM parameters are already being set by Scikit-Learn, what are C and Gamma hyperparameters, and how to tune them usi...

Tuning the hyperparameters in SVM during the training process is challenging, and normally the hyperparameters are tuned by solving an optimization problem. This paper analyses the possible objectives of the optimization for tuning hyperparameters. Through experiments on one synthetic dataset and two ...

Error in svm.default(x, y, scale = scale, ..., na.action = na.action) : NA/NaN/Inf in foreign function call (arg 10) if I do traceback() I see that the parameters (gamma and cost) are passed as NA_real_: what am I doing wrong? how should I use random...
I am running into the problem that the hyperparameters of my svm.SVC() are too wide such that the GridSearchCV() never gets completed! One idea is to use RandomizedSearchCV() instead. But again, my dataset is relative big such that 500 iterations take about 1 hour! ...
Generally speaking, the majority of the hyperparameters are bounded to take integer values (e.g., the number of neurons in a neural network), even if some can vary with continuity within a given interval (e.g., the kernel coefficient𝛾γin a support vector machine), and some are catego...
