WebMay 14, 2016 · However, the implementations behave and perform in somewhat different ways. In this post I will explore some of these differences. Specifically, I will tune an SVC with a radial basis function kernel by performing a grid search over two parameters, C and gamma (called sigma in the R implementation). Each parameter will be tested using 5 … Web1. In order to find the optimum values of C and gamma parameters, you need to perform grid search.

WebJul 27, 2024 · The accuracy for a given C and gamma is the average accuracy during 3-fold cross-validation. The best parameters ( C = 1 and gamma = 0.01 ) of classifier shown in Figure 7 were found using GridSearchCV. Our intuition also confirms this shape of the decision boundary looks better than the one manually chosen. WebWe found that trying exponentially growing sequences of C and γ is a practical method to identify good parameters (for example, C = 2 − 5, 2 − 3, …, 2 15; γ = 2 − 15, 2 − 13, …, 2 3 ).
