  4. Train scikit SVM, customize score assessment

    I plan on using scikit svm for class prediction. I have a two-class dataset consisting of about 100 experiments. Each experiment encapsulates my data-points (vectors) + classification. Training of an SVM accord...Learn More

  5. Python OpenCV SVM implementation

    So I have a matrix with my sample images (all turned into vectors) which was run trough PCA/LDA, and a vector which denotes the class each images belongs to. Now I want to use the OpenCV SVM class to train my S...Learn More

  7. Weird SVM prediction performance in scikit-learn (SVMLIB)

    I am using SVC from scikit-learn on a large dataset of 10000x1000 (10000 objects with 1000 features). I already saw in other sources that SVMLIB doesn't scale well beyond ~10000 objects and I indeed observe thi...Learn More
