Amazon AppStream 2.0 adds support for fully managed image updates

By

Starting today, you can use managed Amazon AppStream 2.0 image updates to keep your AppStream 2.0 images up-to-date with the latest Windows operating system updates, driver updates, and AppStream 2.0 agent software. Previously, AppStream 2.0 images were kept up to date by installing your applications on the latest base image each time a new image was released, or by installing updates for the Windows operating system, your applications, and their dependencies on a new or existing image using the AppStream 2.0 image builder. With this launch, you can select the image that you want to update, and with a single action, AppStream 2.0 creates an image builder in the same AWS account and Region to install the updates and create the new image. After the new image is created, you can test it before updating your production fleets or sharing the image with other AWS accounts. To get started, see Keep Your AppStream 2.0 Image Up-to-Date in the Amazon AppStream 2.0 Administration Guide .

Amazon Fraud Detector automates sampling for imbalanced model training datasets

By

Amazon Fraud Detector is a fully managed service that makes it easy to identify potentially fraudulent online activities, such as the creation of fake accounts or online payment fraud, using customized machine learning (ML) models. To train an ML model, customers provide a dataset that contains examples of legitimate and fraudulent events related to the business activity they want to evaluate for fraud risk. These fraud datasets are often highly imbalanced. For example, a dataset containing one million past transactions may only include 5,000 fraudulent ones, corresponding to a fraud rate of 0.5%. This imbalance in the training data can lead to lower model performance, which results in the customer capturing less fraud. There are a number of common techniques used to treat imbalanced datasets, but applying them requires ML expertise and the best technique often depends on the characteristics of the particular dataset.
