SVM MNIST digit classification in python using GitHub

This code takes a classifier and its set of grid-search parameters, as well as training data and judgements. The result is a triple representing the best configuration, the quality score (measure using accuracy) and the classifier object with the best configuration. The parameters we have used in the GridSearch call are 5-fold cross-validation, with model selection based on accuracy, verbose

Credit scoring using support vector machines with direct

Use Grid Search along with Cross Validation to optimize the parameters for the best model. For a K-Fold cross validation your entire training set will be divided into K equal parts.

How does SVMTRAIN determine Polynomial and RBF Kernel

The Optimize Parameters (Evolutionary) Operator finds the optimal values for a set of parameters using an evolutionary approach which is often more appropriate than a grid search (as in the Optimize Parameters (Grid) Operator) or a greedy search (as in the Optimize Parameters (Quadratic) Operator) and leads to better results. The Optimize Parameters (Evolutionary) Operator might be useful if

scikit learn GridSearchCV with SVM estimator AUC score

Hi all. Would anyone know how SVMTRAIN works when CROSS_VALIDATION is flagged ? I was wondering if by setting this option the algorithm would adjust parameters SVM_C and RBF_GAMMA (for Kernel Type 2 [RBF]) using grid search on them.

python Using GridSearchCV for custom kernel SVM in

Using GridSearchCV for custom kernel SVM in scikit-learn. Ask Question 1. 0. I would like to use scikit-learn's GridSearchCV() to do a grid search on custom parameters in a kernel I have specified. Specifically, the kernel is of the form. SeqKernel(x, y, orig_kernel, cut_off, order) Here, orig_kernel is a kernel typically used in SVM learning (such as linear, polynomial, RBF, or sigmoid). I
