In this workshop, we build a natural language processing (NLP) model to classify sample Twitter comments and customer-support emails using the state-of-the-art BERT model for language representation.

To build our BERT-based NLP model, we use the Amazon Customer Reviews Dataset which contains 150+ million customer reviews from Amazon.com for the 20 year period between 1995 and 2015. In particular, we train a classifier to predict the star_rating (1 is bad, 5 is good) from the review_body (free-form review text).

This workshop is FREE, but would otherwise cost <25 USD.

Open the AWS Management Console

In the AWS Console search bar, type SageMaker and select Amazon SageMaker to open the service console.

In the Notebook instance name text box, enter workshop.

Choose ml.t3.medium (or alternatively ml.t2.medium). We'll only be using this instance to launch jobs. The training job themselves will run either on a SageMaker managed cluster or an Amazon EKS cluster.

Volume size 250 - this is needed to explore datasets, build docker containers, and more. During training data is copied directly from Amazon S3 to the training cluster when using SageMaker. When using Amazon EKS, we'll setup a distributed file system that worker nodes will use to get access to training data.

In the IAM role box, select the default TeamRole.

You must select the default VPC, Subnet, and Security group as shown in the screenshow. Your values will likely be different. This is OK.

Keep the default settings for the other options not highlighted in red, and click Create notebook instance. On the Notebook instances section you should see the status change from Pending -> InService

While the notebook spins up, continue to work on the next section. We'll come back to the notebook when it's ready.

Click on the notebook instance to see the instance details.

Click on the IAM role link and navigate to the IAM Management Console.

Click Attach Policies.

Select IAMFullAccess and click on Attach Policy.

Note: Reminder that you should allow access only to the resources that you need.

Confirm the Policies

Note: Proceed when the status of the notebook instance changes from Pending to InService.
