LIBSVM -- A Library for Support Vector Machines

    https://www.csie.ntu.edu.tw/~cjlin/libsvm/
    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:

    In the model file, after parameters and other informations such as labels , each line represents a support vector. Support vectors are listed in the order of "labels" shown earlier. (i.e., those from the first class in the "labels" list are grouped first, and so on.)

Calculate equation of hyperplane using LIBSVM support ...

    https://stackoverflow.com/questions/51836870/calculate-equation-of-hyperplane-using-libsvm-support-vectors-and-coefficients-i
    I am using the LIBSVM library in python and am trying to reconstruct the equation (w'x + b) of the hyperplane from the calculated support vectors. The model appears to train correctly but I am unable to manually calculate prediction results that match the output of svm_predict for the test data.

machine learning - libsvm data format - Cross Validated
