Calculate number of support vectors in SVM - Cross Validated

WebKernel method. In machine learning, kernel machines are a class of algorithms for pattern analysis, whose best known member is the support-vector machine (SVM). The general task of pattern analysis is to find and study general types of relations (for example clusters, rankings, principal components, correlations, classifications) in datasets. WebKernel models are exactly the same as linear ones, except they first transform the data. Now, the math shows that we're transforming into an even bigger space, so if you're inputs have 1,000...
