Amazon on Wednesday introduced a series of enhancements to SageMaker, its fully-managed machine learning service. SageMaker Workflows is a series of features that makes it easier to manage machine learning pipelines. Amazon is also introducing new built-in algorithms and new framework support, as well as new compliance standards and accreditation. Amazon rolled out SageMaker at last year's AWS re:Invent conference -- along with a slew of other new services, many powered by machine learning. Ahead of this year's conference, Amazon Web Services has announced several improvements to those services, including updates to Amazon Polly, Transcribe and Translate.
