Svm global optima
Web14 apr 2024 · Stock market prediction is the process of determining the value of a company’s shares and other financial assets in the future. This paper proposes a new model where Altruistic Dragonfly Algorithm (ADA) is combined with Least Squares Support Vector Machine (LS-SVM) for stock market prediction. ADA is a meta-heuristic algorithm which … Web22 ago 2024 · Global optimization is a challenging problem of finding an input that results in the minimum or maximum cost of a given objective function. Typically, the form of the objective function is complex and intractable to analyze and is often non-convex, nonlinear, high dimension, noisy, and computationally expensive to evaluate.

Web30 mar 2015 · I'm afraid there is no binary answer to your question. If Linear regression is strictly convex (no constraints on coefficients, no regularizer etc.,) then gradient descent will have a unique solution and it will be global optimum. Gradient descent can and will return multiple solutions if you have a non-convex problem. Web23 feb 2024 · Non-linear SVM: Non-Linear SVM is used for non-linearly separated data, ... Owing to the nature of Convex Optimization, the solution will always be global minimum, not a local minimum.
