The AWS Machine Learning Stack

The AWS machine learning stack offers a range of services and platforms for developers of all skill levels. From pre-built application services to customizable platform services, Amazon provides a variety of options. Some popular services include Amazon Rekognition for image recognition and analysis, Amazon Translate for language translation, and Amazon Lex, which powers the voice assistant Alexa. The stack also includes frameworks such as TensorFlow and MXNet, as well as the ability to deploy custom instances in a Virtual Private Cloud (VPC).

Understanding Amazon SageMaker

Amazon SageMaker is a powerful tool within the AWS machine learning stack. It streamlines the process of building, training, and deploying machine learning models. With pre-built Jupyter notebooks and a library of algorithms, SageMaker offers developers a convenient way to experiment and analyze their data. It also provides one-click training, hyperparameter tuning, and deployment features. SageMaker's modular infrastructure allows for easy scalability and automated model deployment.

The Digital Globe and its Use of Amazon SageMaker

The Digital Globe is a prominent player in the field of satellite imagery and has integrated Amazon SageMaker into its GBDx platform. This platform uses SageMaker as the underlying technology to allow customers to analyze and incorporate machine learning with the available satellite imagery. By leveraging the power of SageMaker, the Digital Globe has been able to enhance its image analytics and provide more advanced capabilities to its customers.

Accessing Data with Raster Data Access (RDA)

The Digital Globe has also developed a service called Raster Data Access (RDA) to enable real-time, random access to their vast Archive of satellite imagery. RDA provides developers with a seamless method to access and process the pixels in Digital Globe's 18-year archive. It utilizes a server-side, graph-Based processing chain to efficiently retrieve and manipulate the desired data. RDA has opened up new possibilities for AI developers and data scientists to extract valuable insights from satellite imagery.

Enabling the AI Ecosystem with SageMaker and RDA

The integration of Amazon SageMaker with RDA has further enhanced the capabilities of both platforms. Developers can now easily access the pixel data from the RDA service and utilize SageMaker's extensive library of algorithms for analysis and machine learning. SageMaker's flexibility allows for the development and deployment of custom models, as well as the use of pre-built algorithms for quick experimentation. With this combination, the Digital Globe and AWS are enabling the AI ecosystem to advance machine learning on satellite imagery.

Training Models with Amazon SageMaker

Amazon SageMaker provides a seamless experience for training machine learning models. Developers can choose the instance Type for training, ranging from GPU instances to more cost-effective options. SageMaker also offers one-click training, which streamlines the process by deploying a training instance, conducting the training, and saving the model artifacts. The recent addition of the hyperparameter tuning feature further optimizes the model training process. Overall, SageMaker simplifies the training workflow and provides cost-saving benefits.

Using SageMaker for Various Applications

SageMaker is a versatile platform that can be applied to various applications beyond image processing.
