A couple of days ago I wrote a post with some additional options to Azure Machine Learning to start in the world of Machine Learning. Not long ago, and following the footsteps of AzureML, Amazon has now presented its ML service called Amazon Machine Learning.
Did not put the Credit Card to still view the internal services that possesses, though the video presentation leaves read an idea starts total integration with AWS.
