Line search parameter
NettetWe also looked at Line Search, a once-popular method to finding the best learning rate at every step of the gradient update. In the next (final) part of the learning parameters series, we will closely look at gradient descent with adaptive learning rate, specifically the following optimizers — AdaGrad, RMSProp, and Adam. The line search approach first finds a descent direction along which the objective function will be reduced and then computes a step size that determines how far should move along that direction. The descent direction can be computed by various methods, such as gradient descent or quasi-Newton method . Se mer In optimization, the line search strategy is one of two basic iterative approaches to find a local minimum $${\displaystyle \mathbf {x} ^{*}}$$ of an objective function $${\displaystyle f:\mathbb {R} ^{n}\to \mathbb {R} }$$. … Se mer • Golden section search • Grid search • Learning rate • Pattern search (optimization) • Secant method Se mer Direct search methods In this method, the minimum must first be bracketed, so the algorithm must identify points x1 and x2 such that the sought minimum lies between them. The interval is then divided by computing $${\displaystyle f(x)}$$ at … Se mer • Dennis, J. E., Jr.; Schnabel, Robert B. (1983). "Globally Convergent Modifications of Newton's Method".
