WebStochastic gradient descent (SGD).Basic idea: in gradient descent, just replace the full gradient (which is a sum) with a single gradient example. Initialize the parameters at … WebStochastic gradient descent (often abbreviated SGD) is an iterative method for optimizing an objective function with suitable smoothness properties (e.g. differentiable or subdifferentiable).It can be regarded as a stochastic approximation of gradient descent optimization, since it replaces the actual gradient (calculated from the entire data set) by …
