Hyper-parameter optimization for support vector machines using stochastic gradient descent and dual coordinate descent
We developed a gradient-based method to optimize the regularization hyper-parameter, C, for support vector machines in a bilevel optimization framework. On the upper level, we optimized the hyper-parameter C to minimize the prediction loss on validation data using stochastic gradient descent. On the...
