Amazon SageMaker connects with the s3 bucket via Jupyter Notebook or Python with boto. It also offers its high-level Python API to create models. Interoperability with new deep learning frameworks like TensorFlow and PyTorch reduces the time it takes to create models.
SageMaker’s Advantages
It uses a debugger that has a predefined range hyperparameters for training.
This aids in the rapid deployment and maintenance of an end to end ML pipeline.
SageMaker Neo can also be used to deploy ML models at edge.
During the execution of the training, the ML computation instance displays the instance type.

Image Source – AWSWhat’s Machine Learning Pipeline?
A Machine Learning Pipeline is the execution mechanism for a machine-learning job. It assists with ML process optimization, management, and development. These are the characteristics of the machine-learning pipeline:
Fetch data to get real-time data from Kafka streams and data repositories. SageMaker must have the data in an AWS S3 bucket to enable it to set up the training task.
Pre-processing involves data wrangling and prepping data for training. Data wrangling can be one of the most tedious parts of a machine-learning project. Amazon SageMaker Processing can be used to run tasks to pre-process training data and post-process it for inference, feature engineering and model evaluation at scale.
Model Training — Data prepared for training and testing with the pre-processing pipeline. Amazon SageMaker already includes popular algorithms. You can import the library and then use it. The current Amazon SageMaker training pipeline looks like this:
Import the training data into the Amazon S3 bucket.
The training begins with the instruction of the ML to access compute instances stored within the EC2 registry.
The model artifacts s3 bucket is where the trained model artifacts are kept.
Why is Amazon SageMaker important?
Amazon SageMaker offers many useful tools that can be used to streamline the ML workflow. Here are some examples:
SageMaker Model Evaluation- SageMaker allows you to evaluate a trained model either offline or online. Requests can be made by using the Jupyter notebook endpoint on historical data (previously-separated data) or cross-validation during offline test. The model is tested online and a traffic threshold is set to handle requests. If everything is working well, the traffic threshold will be set to 100 percent.
Model Deployment – Now that the model has passed the baseline, it’s time for it to be deployed: the trained model artefacts pathway and the inferencecode Docker registry path. SageMaker can be used to create a model by using the CreateModel API. This API defines the HTTPS endpoint and then generates it.
Monitoring- The model’s performance can be tracked in real time, raw data in S3 is recorded and the deviation from the norm is calculated. This will show the instance in which the drift started. The model is then trained with subsequent data and saved in real time in a bucket.
Data Preparation using SageMaker
Data is the foundation of a machine learning model. The data should be of higher quality to make the model more efficient.
Amazon SageMaker makes data labelling easy. Amazon SageMaker allows users to choose between a vendor, public, or private workforce. The user can either do the labelling on its own or with third-party APIs. There are confidentiality agreements. An Amazon Mechanical Turk Workforce service creates a labelling task for the public workforce and reports on the success or failure. These are the steps:
Create a manifest file from the data in the s3 bucket that will be used for the labelling task.
To create a labelling workforce, select the type of workforce.
You can create a labelling task by choosing a job type such as Image Classification, Text Classification or Bounding Box.
If Bounding Box is your task, draw a box around it and label it. To visualise your results, you can view the confidence score and other data.
SageMaker offers Hyperparameter Tuning
Hyperparameters are parameters that determine the architecture of a model. This is also known as hyperparameter tuning. It includes the following methods:
Random Search- This is a random selection made of hyperparameter combinations and a training task executed on them. SageMaker allows parallel execution of tasks to find the optimal hyperparameter, without interfering in the current training job.
SageMaker’s Bayesian Search algorithm can also be used. The algorithm first checks the performance of hyperparameter combinations previously used in a task, and then it investigates the new combination using that list.
Steps to Hyperparameter Tuning
The measurements are used to evaluate a training task when creating a hyperparameter tuning job. A single operation can only have 20 criteria. Each parameter must be given a unique name and a regular formula to extract information from logs.
The declared hyperparameter ranges of the parameter type, i.e. a distinction between the ParameterRanges JSON objects.
Create a SageMaker Notebook and connect to SageMaker’s Boto3 client.
Next, create the bucket and the data output location and then execute the hyperparameter tuning task as described in steps 1 and 2.
You can monitor the progress of the hyperparameter tuning tasks running simultaneously and find the best model by clicking on the best job in SageMaker’s interface.
Best practices for Amazon Sagemaker
SageMaker allows you to specify the number of parameters. SageMaker allows you to use 20 parameters in a hyperparameter tune task to limit search space and find the best variables for a model.
