    Modified support vector machines in financial time series forecasting The financial market is a complex, evolutionary, and nonlinear dynamical system. The financial time series are inherently noisy, non-stationary, and deterministically chaotic. This means that the distribution of financial time series is changing over the time.Cited by: 525

    This paper proposes a modified version of support vector machines, called C-ascending support vector machine, to model non-stationary financial time series. The C -ascending support vector machines are obtained by a simple modification of the regularized risk function in support vector machines, whereby the recent ε -insensitive errors are penalized more heavily than the distant ε …Cited by: 525

Support-vector machine - Wikipedia

    https://en.wikipedia.org/wiki/Support-vector_machine
    In machine learning, support-vector machines are supervised learning models with associated learning algorithms that analyze data used for classification and regression analysis. Given a set of training examples, each marked as belonging to one or the other of two categories, an SVM training algorithm builds a model that assigns new examples to one category or the other, making it a non-probabilistic binary linear classifier. An SVM model …

    Support Vector Machines (Kernels) The SVM algorithm is implemented in practice using a kernel. The learning of the hyperplane in linear SVM is done by transforming the problem using some linear algebra, which is out of the scope of this introduction to SVM.

    Sep 12, 2019 · The two main advantages of support vector machines are that: 1. They’re accurate in high dimensional spaces; 2. and, they use a subset of training points in the decision function (called support vectors), so it’s also memory efficient. The disadva...
