Introduction
At its most basic, machine learning (ML) is designed to provide
digital tools and services to learn from data, identify patterns,
make predictions, and then act on those predictions. Almost all
artificial intelligence (AI) systems today are created using ML. ML
uses large amounts of data to create and validate decision logic.
This decision logic forms the basis of the
AI model.
Scenarios where AWS machine learning services may be applied
include:
-
Specific use cases — AWS machine learning services
can support your AI powered use cases with a broad range of pre-built algorithms, models,
and solutions for common use cases and industries. You have a choice of 23 pre-trained
services, including Amazon Personalize, Amazon Kendra, and Amazon Monitron.
-
Customizing and scaling machine learning — Amazon SageMaker AI
is designed to help you build, train, and deploy ML models for any use case. You can build
your own or access open source foundational models on AWS through Amazon SageMaker AI and Amazon Bedrock.
-
Accessing specialized infrastructure — Use the ML
frameworks and infrastructure provided by AWS when you require even greater flexibility
and control over your machine learning workflows, and are willing to manage the underlying
infrastructure and resources yourself.
This decision guide will help you ask the right questions, evaluate
your criteria and business problem, and determine which services are
the best fit for your needs.
Understand
As organizations continue to adopt AI and ML technologies, the
importance of understanding and choosing among AWS ML services is an
on-going challenge.
AWS provides a range of ML services designed to help organizations
to build, train, and deploy ML models more quickly and easily. These
services can be used to solve a wide range of business problems such
as customer churn prediction, fraud detection, and image and speech
recognition.
Before diving deeper into AWS ML services, let's look at the
relationship between AI and ML.
-
At a high level, artificial intelligence is
a way to describe any system that can replicate tasks that
previously required human intelligence. Most AI use cases are
looking for a probabilistic outcome—making a prediction or
decision with a high degree of certainty, similar to human
judgement.
-
Almost all AI systems today are created using machine
learning. ML uses large amounts of data to create and
validate decision logic, which is known as a model.
-
Classification AI is a subset of ML that recognizes patterns to
identify something. Predictive AI is a subset of ML that
predicts future trends based on statistical patterns an
historical data.
-
Finally, generative AI is a subset of deep learning that can
create new content and ideas, like conversations, stories,
images, videos, and music. Generative AI is powered by very
large models that are pretrained on vast corpora of data, called
the Foundation Models or
FMs. Amazon Bedrock
is a fully managed service that offers
a choice of high-performing FMs for building and scaling
generative AI
applications. Amazon Q Developer and
Amazon Q Business are generative-AI powered
assistants for specific use cases.
This guide is designed primarily to cover services in
the Classification AI and Predictive
AI machine learning categories.
In addition, AWS offers specialized, accelerated hardware for high
performance ML training and inference.
-
Amazon EC2 P5 instances are equipped with NVIDIA H100
Tensor Core GPUs, which are well-suited for both training and
inference tasks in machine
learning. Amazon EC2 G5 instances feature up to 8 NVIDIA A10G
Tensor Core GPUs, and second generation AMD EPYC processors, for
a wide range of graphics-intensive and machine learning use
cases.
-
AWS Trainium is the second-generation ML
accelerator that AWS has purpose-built for deep learning (DL)
training of 100B+ parameter models.
-
AWS Inferentia2-based Amazon EC2 Inf2 instances are designed to deliver high
performance at the lowest cost in Amazon EC2 for your DL and
generative AI inference applications.
Consider
When solving a business problem with AWS ML services, consideration
of several key criteria can help ensure success. The following
section outlines some of the key criteria to consider when choosing
a ML service.
- Problem definition
-
Problem definition
The first step in the ML lifecycle is to frame the business problem.
Understanding the problem you are trying to solve is essential for
choosing the right AWS ML service, as different services are
designed to address different problems. It is also important to
determine whether ML is the best fit for your business problem.
Once you have determined that ML is the best fit, you can start by
choosing from a range of purpose-built AWS AI services (in areas
such as speech, vision and documents).
Amazon SageMaker AI provides fully managed infrastructure if you need
to build and train your own models. AWS offers an array of advanced
ML frameworks and infrastructure choices for the cases where you
require highly customized and specialized ML models. AWS also offers
a broad set of popular foundation models for building new
applications with generative AI.
- ML algorithm
-
ML algorithm
Choosing the ML algorithm for the business problem you are trying to
solve depends on the type of data you are working with, as well as
the desired outcomes. The following information outlines how each of
the major AWS AI/ML service categories empowers you to work with its
algorithms:
-
Specialized AI services: These services offer a limited ability
to customize the ML algorithm, as they are pre-trained models
optimized for specific tasks. You can typically customize the
input data and some parameters, but do not have access to the
underlying ML models or the ability to build your own models.
-
Amazon SageMaker AI: This service provides the most flexibility and
control over the ML algorithm. You can use SageMaker AI to build
custom models using your own algorithms and frameworks, or use
pre-built models and algorithms provided by AWS. This allows for
a high degree of customization and control over the ML process.
-
Lower-level ML frameworks and infrastructure: These services
offer the most flexibility and control over the ML algorithm.
You can use these services to build highly customized ML models
using their own algorithms and frameworks. However, using these
services requires significant ML expertise and may not be
feasible for all every use case.
- Security
-
Security
If you need a private endpoint in your VPC, your options will vary
based on the layer of AWS ML services you are using. These include:
-
Specialized AI services: Most specialized AI services do not
currently support private endpoints in VPCs. However, Amazon Rekognition Custom Labels and Amazon Comprehend
Custom can be accessed using VPC endpoints.
-
Core AI services: Amazon Translate, Amazon Transcribe, and
Amazon Comprehend all support VPC endpoints.
-
Amazon SageMaker AI: SageMaker AI provides built-in support for VPC
endpoints, allowing you to deploy their trained models as an
endpoint accessible only from within their VPC.
-
Lower-level ML frameworks and infrastructure: You can deploy
your models on Amazon EC2 instances or in containers within your
VPC, providing complete control over the networking
configuration.
- Latency
-
Latency
Higher-level AI services, such as Amazon Rekognition and Amazon Transcribe, are designed to
handle a wide variety of use cases and
offer high performance in terms of speed. However, they might not
meet certain latency requirements.
If you are using lower-level ML frameworks and infrastructure, we
recommended leveraging Amazon SageMaker AI. This option is generally
faster than building custom models due to its fully managed service
and optimized deployment options. While a highly optimized custom
model may outperform SageMaker AI, it will require significant
expertise and resources to build.
- Accuracy
-
Accuracy
The accuracy of AWS ML services varies based on the specific use
case and level of customization required. Higher-level AI services,
such as Amazon Rekognition, are built on pre-trained models that
have been optimized for specific tasks and offer high accuracy in
many use cases.
In some cases, you can choose to use Amazon SageMaker AI, which
provides a more flexible and customizable platform for building and
training custom ML models. By building your own models, you may be
able to achieve even higher accuracy than what is possible with
pre-trained models.
You can also choose to use ML frameworks and infrastructure, such as
TensorFlow and Apache MXNet, to build highly customized models that
offer the highest possible accuracy for your specific use case.
- AWS and responsible AI
-
AWS and responsible AI
AWS builds foundation models (FMs) with responsible AI in mind at
each stage of its development process. Throughout design,
development, deployment, and operations we consider a range of
factors including:
-
Accuracy (how closely a summary matches the underlying document;
whether a biography is factually correct)
-
Fairness, (whether outputs treat demographic groups similarly)
-
Intellectual property and copyright considerations
-
Appropriate usage (filtering out user requests for legal advice,
or medical diagnoses, or illegal activities)
-
Toxicity (hate speech, profanity, and insults)
-
Privacy (protecting personal information and customer prompts)
AWS builds solutions to address these issues into the processes used
for acquiring training data, into the FMs themselves, and into the
technology used to pre-process user prompts and post-process
outputs.
