Amazon's expertise and the gradient descent algorithm

Amazon has been using machine learning for the retail side of its business and has build a serious expertise in predictive analytics. This expertise translates into the choice of algorithm powering the Amazon ML service.

The Stochastic Gradient Descent (SGD) algorithm is the algorithm powering Amazon ML linear models and is ultimately responsible for the accuracy of the predictions generated by the service. The SGD algorithm is one of the most robust, resilient, and optimized algorithms. It has been used in many diverse environments, from signal processing to deep learning and for a wide variety of problems, since the 1960s with great success. The SGD has also given rise to many highly ...
