13.04.2021 · >>> m = libsvm.svm_train(prob, param) # m is a ctype pointer to an svm_model # Convert a tuple of ndarray (index, data) to feature_nodearray, a ctypes structure # Note that index starts from 0, though the following example will be changed to 1:1, 3:1 internally

20.05.2021 · libsvm instances during the unit tests are influenced by other coexisting instances and cause test failures. While trying to cover tests for WASM loaded SVM's predict, I've encountered an issue of incorrect prediction results between running …

The value at index 1 of the first vector is the value of the kernel function of the first vector from the first example with itself (i.e. (1x1)+(1x1)+(1x1)+(1x1) = 4), the second is the value of the kernel function of the first vector with the second (i.e. (1x3)+(1x3)=6). It follows on like that for the rest of the example.

Introduction. LIBSVM is an integrated software for support vector classification, (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM).It supports multi-class classification. Since version 2.8, it implements an SMO-type algorithm proposed in this paper: R.-E. Fan, P.-H. Chen, and C.-J. Lin. Working set selection using second order …

In the libsvm documentation, it is stated that: For precomputed kernels, the first element of each instance must be the ID. For example, samples = [ [1, 0, 0, 0, 0], [2, 0, 1, 0, 1], [3, 0, 0, 1, 1], [4, 0, 1, 1, 2]] problem = svm_problem (labels, samples) param = svm_parameter (kernel_type=PRECOMPUTED) What is a ID?
