You can view the details for the CREATE MODEL command in the Amazon Redshift documentation. IAM_ROLE 'arn:aws:iam:::role/Redshift-ML' You can import that model into Amazon Redshift using the CREATE MODEL command as below: CREATE MODEL demo_ml.xgboost_predict_ageįUNCTION predict_age (float,float,float, float,float,float, float) Let us assume that you have an XGBoost model that you trained with Amazon SageMaker, and you want to bring that model to Amazon Redshift for local inference. Creating Your Model in Amazon Redshift by importing your pre-trained model ![]() If you already a cluster in the SQL_PREVIEW maintenance track, then upgrade the cluster to 9 release or later. You have to create your Amazon Redshift cluster with the SQL_PREVIEW maintenance track. Create Amazon Redshift cluster with Amazon Redshift ML preview We updated the Amazon Redshift ML preview, and now you can bring your pre-trained XGBoost model in Amazon SageMaker to Amazon Redshift for in-database/local inference. You can these models for inference using SQL. You can view the Amazon Redshift documentation for details. You can also choose your pre-processors or hyperparameters for training. As an advanced user, you can either select problem type objective or XGBoost as your algorithm. Amazon Redshift ML leverages SageMaker Autopilot to automatically pre-process the data, select the algorithm and problem types such as binary classification, multi-class classification, or regression, and then trains and tunes your model. Amazon Redshift ML allows you to use your data in Amazon Redshift with Amazon SageMaker, a fully managed ML service, without requiring you to become experts in ML. "These are all just pieces of the puzzle scattered around different silos, but when combined, we can get a much clearer picture," said Wood.Amazon Redshift ML (preview) makes it easy for SQL users to create, train, and deploy ML models using familiar SQL commands. HealthLake can automatically load structured data but also extract information such as patient names from physician notes and added that to a data lake. "We can bring it all together in minutes," said Wood. "It is a Herculean effort," he said, to analyze all that data. ![]() ![]() For early diagnosis of diabetes, doctors have to go through hundreds of thousands of data points from donor notes and prescriptions and the rest. Wood gave an example of HealthLake used in the detection of diabetes. To ameliorate all that, Wood unveiled Amazon HealthLake, a way to "store, transform, and analyze health and life science data in the cloud at petabyte scale," as the company puts it. The work in that field is hampered by the way data is spread throughout numerous repositories in different formats, requiring weeks or months to prepare data, he said. Wood discussed another vertical market application, healthcare, and life sciences. ![]()
