Easily train models using datasets labeled by Amazon SageMaker Ground Truth
Data scientists and developers can now easily train machine learning models on datasets labeled by Amazon SageMaker Ground Truth. Amazon SageMaker Training now accepts the labeled datasets produced in augmented manifest format as input through both AWS Management Console and Amazon SageMaker Python SDK APIs. Last month during AWS re:Invent, we launched Amazon SageMaker Ground […]
Read MoreAnalyzing contact center calls—Part 1: Use Amazon Transcribe and Amazon Comprehend to analyze customer sentiment
Contact centers aiming to improve overall operational efficiency have an imperative to understand caller-agent dynamics. In part one of this two-part blog post series we’ll show you how you can use Amazon Transcribe and Amazon Comprehend to transform call recordings from audio to text and then run sentiment analysis on the transcripts. We will demonstrate how […]
Read MoreScalable multi-node training with TensorFlow
We’ve heard from customers that scaling TensorFlow training jobs to multiple nodes and GPUs successfully is hard. TensorFlow has distributed training built-in, but it can be difficult to use. Recently, we made optimizations to TensorFlow and Horovod to help AWS customers scale TensorFlow training jobs to multiple nodes and GPUs. With these improvements, any AWS customer […]
Read MoreAmazon SageMaker Automatic Model Tuning now supports early stopping of training jobs
In June 2018, we launched Amazon SageMaker Automatic Model Tuning, a feature that automatically finds well-performing hyperparameters to train a machine learning model with. Unlike model parameters learned during training, hyperparameters are set before the learning process begins. A typical example of the use of hyperparameters is the learning rate of stochastic gradient procedures. Using […]
Read MoreAnomaly detection on Amazon DynamoDB Streams using the Amazon SageMaker Random Cut Forest algorithm
Have you considered introducing anomaly detection technology to your business? Anomaly detection is a technique used to identify rare items, events, or observations which raise suspicion by differing significantly from the majority of the data you are analyzing. The applications of anomaly detection are wide-ranging including the detection of abnormal purchases or cyber intrusions in […]
Read MoreAnnouncing the Winners of the 2018 AWS AI Hackathon
We’re excited to announce the winners of the 2018 AWS AI Hackathon. Horacio Canales has won first place with his “Second Alert” project. This project enables users from around the world to identify missing persons, including human trafficking victims, children too young to remember their family members’ names, and mentally handicapped individuals. Horacio built the […]
Read MoreAmazon SageMaker now comes with new capabilities for accelerating machine learning experimentation
Data scientists and developers can now quickly and easily organize, track, and evaluate their machine learning (ML) model training experiments on Amazon SageMaker. We are introducing a new Amazon SageMaker Search capability that lets you find and evaluate the most relevant model training runs from the hundreds and thousands of your Amazon SageMaker model training […]
Read MoreAmazon SageMaker notebooks now support Git integration for increased persistence, collaboration, and reproducibility
It’s now possible to associate GitHub, AWS CodeCommit, and any self-hosted Git repository with Amazon SageMaker notebook instances to easily and securely collaborate and ensure version-control with Jupyter Notebooks. In this blog post, I’ll elaborate on the benefits of using Git-based version-control systems and how to set up your notebook instances to work with Git repositories. Data […]
Read MoreSemantic Segmentation algorithm is now available in Amazon SageMaker
Amazon SageMaker is a managed and infinitely scalable machine learning (ML) platform. With this platform, it is easy to build, train, and deploy machine learning models. Amazon SageMaker already has two popular built-in computer vision algorithms for image classification and object detection. The Amazon SageMaker image classification algorithm learns to categorize images into a set of […]
Read MoreIntroducing Amazon Translate Custom Terminology
Amazon Translate is a neural machine translation service that delivers fast, high-quality, and affordable language translation. Today, we are introducing Custom Terminology, a feature that customers can use to customize Amazon Translate output to use company- and domain-specific vocabulary. By uploading and invoking Custom Terminology with translation requests, customers have the ability to ensure that their […]
