However, with the abundance of compute resources and the demand for business-driven use cases, the roles have shifted. Business objectives now drive the adoption of machine learning, such as fraud detection or natural language processing.

Despite the growing popularity of machine learning, there are still challenges to overcome. The skills gap is a significant hurdle, with a shortage of professionals who possess the necessary expertise. Additionally, machine learning is a time-consuming and complex process that requires time and skill to achieve successful results. Finally, finding the right business use case and selecting the appropriate algorithm or model can be a challenge, leading to project failures.

AWS Mission in Machine Learning

AWS aims to make it easier for developers to build, scale, and Apply machine learning in their applications. Our mission is to put machine learning in the hands of all developers and organizations. To achieve this, we provide a wide range of machine learning services and frameworks, catering to developers with different levels of experience and expertise.

AWS Machine Learning Services

At AWS, our machine learning services can be categorized into three layers: AI services, machine learning developer tools, and machine learning frameworks and infrastructure.

AI Services

The top layer of our machine learning services is AI services. These services use pre-trained or custom-trained models and provide high-level APIs for tasks such as image recognition, translation, transcription, etc. These services can be easily integrated into applications using simple API calls.

Machine Learning Developer Tools

The middle layer of our machine learning services consists of developer tools for machine learning. These tools provide an integrated development environment (IDE) for running common activities in machine learning, such as debugging, experimenting, and hyperparameter tuning. With these tools, developers and data scientists can build, train, and deploy models efficiently.

Machine Learning Frameworks and Infrastructure

The bottom layer of our machine learning services is dedicated to machine learning frameworks and infrastructure. These services are aimed at experts who require full control over their application logic and infrastructure. AWS supports popular machine learning frameworks like TensorFlow, MXNet, and PyTorch. Additionally, we have developed an open-source library called DGL (Deep Learning Java Library), which abstracts away the complexities of these frameworks and provides a scalable and supported solution.

Introducing DGL (Deep Learning Java Library)

DGL is a machine learning framework developed specifically for Java. It provides most of the machine learning features, including training and inference, and has built-in support for multi-threading and memory control.
