Using AutoML to automate selection of machine learning models and hyperparameters

Francesca Lazzeri (Microsoft), Wee Hyong Tok (Microsoft)
1:00pm1:40pm Thursday, April 18, 2019
Machine Learning, Models and Methods
Location: Grand Ballroom West
Secondary topics:  AI case studies, Automation in machine learning and AI, Deep Learning and Machine Learning tools

Who is this presentation for?

Data Scientists, Data Engineers, AI Developers

Level

Intermediate

Prerequisite knowledge

• Experience coding in Python • A basic understanding of machine learning and deep learning topics and terminology • Familiarity with Time Series Forecast (useful but not required)

What you'll learn

The primary audiences for this talk will be data scientists and AI developers of intermediate to expert skill levels and researchers familiar with machine learning. We can assume that they know basic python and are familiar with the high-level concepts of model deployment. By the end of this session, the attendees should be able to understand the key concepts and principles of time series forecast, set up their own environment for performing AutoML, build different machine learning models using AutoML libraries, review training results, register the best model, deploy and test it.

Description

Automated machine learning (AutoML) enables both data scientists and domain experts (with limited machine learning training) to be productive and efficient. In recent years, AutoML is seen as a fundamental shift in which organizations can approach making machine learning more accessible to both experts and non-experts.

Most real-world data science projects are time-consuming, resource-intensive, and challenging.
Besides data preparation, data cleaning, and feature engineering, data scientists often spend significant amount of time on model selection and tuning of hyper-parameters. Automated machine learning changes that, making it easier to build and use machine learning models in the real world.

This talk is a gentle introduction into how AutoML works, and the state-of-art AutoML capabilities that are available. In this talk, you’ll learn how to use auto ML to automate selection of machine learning models and automate tuning of hyper-parameters.

During this talk, Francesca and Wee Hyong will focus on the following topics:
• Introduction to AutoML
a. Understand how AutoML works
b. Learn about the libraries and cloud services that support AutoML

• Use Case – Energy Demand Forecasting
c. Introduction to the use case
d. Data set exploration
e. Feature engineering
f. Data pre-processing

• Getting started with Automated Machine Learning
a. How to generate a forecast machine learning model using Automated machine learning
b. Perform data pre-processing with Automated machine learning
c. Perform algorithm selection with Automated machine learning
d. Perform hyperparameter selection with Automated machine learning
e. Train multiple models on a remote cluster
f. Review training results and register the best model
g. Deploy your model as web service
