Oct 01, 2019 Mini Batch Gradient Descent. We have seen the Batch Gradient Descent. We have also seen the Stochastic Gradient Descent. Batch Gradient Descent can be used for smoother curves. SGD can be used when the dataset is large. Batch Gradient Descent converges directly to minima. SGD converges faster for larger datasets.

Get PriceEmail InquiryThe result of the previous Example is indicative of a major computational advantage of stochastic/mini-batch gradient descent over the standard batch version for dealing with large datasets. When initialized far from a point of convergence the stochastic/mini-batch methods tend in practice to progress much faster towards a solution.
