4.12Gradient descent method ThisMPPTalgorithm is suitable for fast changing environmental conditions; it also improves the efficiency during tracking as compare to other conventional methods. The method is based on numerical calculation which is used to solvenonlinear problemsto optimize some objective func...
3.1.3Subgradient descent method Differentiability of the objective functionfis critical for the validity of gradient methods to solve problems(3.4)and(3.9). However, there are plenty of nondifferentiable functions (e.g.,ℓ1minimization and nuclear norm minimization). This will result in expensive ...

An improved gradient descent method with multiple variable step sizes for identifying nonlinear parameters of moving-coil loudspeakers is proposed. This method monitors parameters trends during identification and adaptively multiplies or attenuates corresponding step sizes, eliminating the need for manual adjust...
In particular (1) we perform extensive experiments on three datasets, MNIST, USPS and Spambase, in order to analyse the effectiveness of the gradient-descent method against non-linear support vector machines, and conclude that carefully reduced kernel smoothness can significantly increase robustness to...
