Machine learning has been developed over the years and brings many discoveries and inventions to us. It is the ability to increase the strength and effectiveness of a business, so many companies today rely on machine learning. Amazon introduced the SageMaker solution for a build, train and machine learning model. Let’s learn more about AWS SageMaker in this article. Here we will discuss a basic framework to get started with AWS SageMaker.

What is Amazon Sagemaker?

Get some clarity on Amazon Machine Learning vs. Sagemaker before you start. Amazon Machine Learning uses several AWS resources such as identifying a pattern in a dataset and later using them for responsive application development. Whereas Amazon offers a fully managed solution called SageMaker that empowers data scientists and developers to quickly create, train and deploy machine learning models.

SageMaker comes with direct deployment of machine learning modal in a hosted environment ready for production.

SageMaker offers you an advance option to use pre-built algorithms that fit your business project needs or you can build and train your own ML model from scratch according to the requirements. Similar tools are available for model debugging or adding manual review procedures to model predictions.

Why Should You Use It?

The complexity of the machine learning project in any enterprise increases with the expansion of scale. This is because machine learning projects comprise of three key stages – build, train and deploy – each of which can continuously loop back into each other as the project progresses. And as the amount of data being dealt with increases, so does the complexity. And if you are planning to build a ML model that truly works, your training data sets will tend to be on the larger side.

Typically, different skill sets are required at different stages of a machine learning project. Data scientists are involved in researching and formulating the machine learning model, while developers are the ones taking the model and transforming it into a useful, scalable product or web-service API. But not every enterprise can put together a skilled team like that, or achieve the necessary coordination between data scientists and developers to roll out workable ML models at scale.

This is exactly where Amazon Sagemaker steps in. As a fully managed machine learning platform, SageMaker abstracts the software skills, enabling data engineers to build and train the machine learning models they want with an intuitive and easy-to-use set of tools. While they play to the core strengths of working with the data and crafting the ML models, the heavy lifting needed for developing these into a ready-to-roll web-service API is handled by Amazon Sagemaker.

How It Works?

With a 3-step model of Build-Train-Deploy, Amazon SageMaker simplifies and streamlines your machine learning modelling. Let’s take a quick look at how it works.

Amazon SageMaker offers you a completely integrated development environment for machine learning that lets you improve your productivity. With the help of its one-click Jupyter notebooks, you can build and collaborate with lightning speed. Sagemaker also offers you a one-click sharing facility for these notebooks. The entire coding structure is captured automatically, which allows you to collaborate with others without any hurdle.

Apart from this, the Amazon SageMaker Autopilot is the first automated machine learning capability of this industry. It allows you to have complete control as well as visibility into your respective machine learning models. The traditional approaches of automated machine learning do not allow you to peek in the data or logic used to create that model. However, the Amazon Sagemaker Autopilot is capable of integrating with Sagemaker Studio and provides you complete visibility into the raw data and information used in the creation.

One of the highlights of Amazon SageMaker is its Ground Truth feature that helps you in building as well as managing precise training datasets without facing any hurdle. The Ground Truth provides you complete access to the labelers via Amazon Mechanical Trunk along with pre-built workflows as well as interfaces for common labeling tasks. The Amazon Sagemaker comes with the support of various deep learning frameworks including PyTorch, TensorFlow, Apache MXNet, Chainer, Gluon, Keras, Scikit-learn, and Deep-Graph library.


Using Amazon SageMaker Experiments, you can easily organize, track, and evaluate every iteration to machine learning models. Training a machine learning model packs various iteration to measure and isolate the impact of changing algorithm versions, model parameters, and changing datasets. The Sagemaker Experiments help you in managing these iterations via capturing the configurations, parameters, and results automatically, and storing them as experiments.

SageMaker comes with a debugger functionality that is capable of analyzing, debugging, and fixing all the problems in your machine learning model. Debugger makes the training process entirely transparent by capturing real-time metrics during the process. The Sagemaker Debugger also comes with a facility of generating warnings as well as remediation advice if any common problems are detected during the training process.

Apart from this, AWS TensorFlow optimization offers you a scaling facility of up to 90% with the help of its gigantic 256 GPUs. Using this, you can experience precise, and sophisticated training models in very little time. Furthermore, the Amazon Sagemaker comes with a Managed Spot Training that helps reduce training costs up to 90%.


Amazon SageMaker offers you a one-click deployment facility so that you can easily generate predictions for batch or real-time data. You can easily deploy your model on auto-scaling Amazon machine learning instances across various availability zones for improved redundancy. You just need to specify the desired maximum and minimum numbers, and the type of instance, and then leave the rest to Amazon Sagemaker.

The major problem that can affect the accuracy of your entire operation is the difference between data used to generate predictions and the data used to train models. The SageMaker Model Monitor can help you in getting out of this puzzle by detecting and remediating concept drift. The Sagemaker Model Monitor detects the concept drift in all of your deployed models automatically and then provides alerts to identify the main source of the problem.

The Amazon Sagemaker also packs Augmented AI facility, with the help of which, you can easily allow human reviewers to step in if the model is unable to make high confidence precise predictions. Moreover, the Amazon Elastic Inference is capable of minimizing your machine learning inference costs by 75%. Lastly, Amazon also allows you to integrate Sagemaker with Kubernetes, by which you can easily automate the deployment, scale, and management of your applications.

So, there you have it, a look at how Amazon Sagemaker can help build, train and deploy machine learning models to suit your project requirements.

Machine Learning with AWS SageMaker

Data Pre-processing with SageMaker

The first thing we look at is exploring or prepossessing data using SageMaker. Data prepossessing involves methods. The first method involves using a Jupyter notebook on SageMaker notebook instance.

The notebook instance is ideal for writing code to create model training jobs and to deploy models to SageMaker hosting. The notebook instance also helps in testing and validating your models. Amazon SageMaker batch transform is also an ideal approach for using a model to transform data.

Training the ML Model with SageMaker

The comprehensiveness of each step in the use of SageMaker validates amazon SageMaker pricing. The second step in machine learning with SageMaker, after generating example data involves training a model. The first step in training a model involves the creation of a training job. The training job contains specific information such as the URL of Amazon S3, where the training data is stored. Also, training job contains information on the URL of the S3 bucket selected for storing the output.

The training job also contains compute resources ideal for model training. Generally, the compute resources are ML compute instances subject to management by Amazon SageMaker. Most important of all, the training job also includes the Amazon Elastic Container Registry path that stores the training code.

Training a model with Amazon SageMaker involves different options. The first option is to use Amazon SageMaker algorithms or using Apache Spark with SageMaker. You can also use custom algorithms or submit a custom code for training with deep learning frameworks. You could also use algorithms available for subscription on the AWS marketplace.

Deploying the Model Using SageMaker

The final stage in our discussion is here! Now, we can learn about deploying a machine learning model in Amazon SageMaker. After the model training process, the deployment can follow two ways. The first route involves establishing a persistent endpoint for obtaining one prediction at a time through SageMaker hosting services.

SageMaker batch transform is ideal for obtaining predictions from an entire dataset. Another important factor which we should not miss out in this introductory discussion for SageMaker is amazon SageMaker pricing. You should note that billing for training and hosting depends on minutes of usage without upfront commitments or minimum fees. It’s not free!
