This document summarizes the evolution of machine learning tools in the cloud from 2015 to 2017. It describes how in 2015, major cloud providers like Azure, Amazon, and Google launched early machine learning services. From 2015 to 2016, these providers also released popular deep learning frameworks like TensorFlow as open source. During this time period, the providers began offering deep learning models and GPU computing as cloud services. The document argues that these developments have helped democratize artificial intelligence and machine learning.
