OML feature highlight: Deploy a Python XGBoost Model using OML Services OML Office Hours Sherry LaMonica Principal Member of Technical Staff, Oracle Machine Learning Supported by Marcos Arancibia and Mark Hornick Product Management, Oracle Machine Learning Move the Algorithms; Not the Data! Copyright © 2021, Oracle and/or its affiliates. This Session will be Recorded

• Motivation • Overview of OML Services • Overview of ONNX • Demo • Train a Python XGBoost model • Materialize the model to ONNX format • Deploy the ONNX model using OML Services on Autonomous Database • Q&A Topics for today Copyright © 2021, Oracle and/or its affiliates 2

Motivation 3 Copyright © 2021, Oracle and/or its affiliates

• Simplifies the task of putting models into production • Algorithm not available in-database • Very fast scoring • Cost effective • Requirement to separate development and deployment environments, for example, web applications • OML Services contains ONNX support for classification and regression models Motivation 4 Why deploy an ONNX model using OML Services?

ONNX 10 Copyright © 2021, Oracle and/or its affiliates

ONNX is an open standard format for representing and storing machine learning models. It is the basis of an open ecosystem with interchangeable ML models. Benefits include: • Promoting interoperability, portability, and efficiency • Integration into different machine learning frameworks and tools - XGBoost, SciKit-Learn, PyTorch, TensorFlow, and others • ONNX models run on a variety of ONNX compliant tools and frameworks for scoring 11 Copyright © 2021, Oracle and/or its affiliates ONNX
