10.5. Mini-batch Stochastic Gradient Descent¶ In each iteration, the gradient descent uses the entire training data set to compute the gradient, so it is sometimes referred to as batch gradient descent. Stochastic gradient descent (SGD) only randomly select one example in each iteration to compute the gradient.

In general, minibatch stochastic gradient descent is faster than stochastic gradient descent and gradient descent for convergence to a smaller risk, when measured in terms of clock time. Exercises ¶ Modify the batch size and learning rate and observe the rate of decline for the value of the objective function and the time consumed in each epoch.

If gradient descent is used, the computing cost for each independent variable iteration is \(\mathcal{O}(n)\), which grows linearly with \(n\). Therefore, when the model training data instance is large, the cost of gradient descent for each iteration will be very high. Stochastic gradient descent (SGD) reduces computational cost at each iteration.
