Cocalc 05 Svm Conic Ipynb

In this notebook we come back to the concept of training support vector machines as we did in the first SVM notebook The difference is that we shall now be solving the dual problems related to training the SVM's using the conic quadratic optimization by explicitly calling the Mosek solver, which should yield more stable numerical... The first part of this notebook shall therefore consist of data imports and other things that need no further explanation. Please move directly to the cell entitled "Conic optimization model" if you already have the data loaded from there. Point of attention: An important difference with the first notebook will be the fact that we will eliminate the 'intercept' bbb of the SVM to keep our equations simple. This cell selects and verifies a global SOLVER for the notebook.

If run on Google Colab, the cell installs Pyomo and ipopt, then sets SOLVER to use the ipopt solver. If run elsewhere, it assumes Pyomo and the Mosek solver have been previously installed and sets SOLVER to use the Mosek solver via the Pyomo SolverFactory. It then verifies that SOLVER is available.

Still effective in cases where number of dimensions is greater than the number of samples. Uses a subset of training points in the decision function (called support vectors), so it is also memory efficient. Versatile: different Kernel functions can be specified for the decision function. Common kernels are provided, but it is also possible to specify custom kernels. If the number of features is much greater than the number of samples, avoid over-fitting in choosing Kernel functions and regularization term is crucial. There was an error while loading.

Support vector machines (SVMs) are a particularly powerful and flexible class of supervised algorithms for both classification and regression. In this section, we will develop the intuition behind support vector machines and their use in classification problems.
